Last week while attending the 50th Anniversary celebrations of Aquasystems in Belgium and France I was honoured to accept a surprise award on behalf of the entire Aeris Global team in New Zealand and Australia.

The award recognised Aeris Global as achieving the highest total volume of aquaturbo® surface aerator sales in the world.

I was proud and humbled to accept the award and completely taken by surprise considering I was attending the event solely as a celebration of the Aquasystems milestone.

The amazing gala event was a logistical achievement, staged over three days in two countries at multiple venues and attended by representatives from partner organisations in every corner of the globe.

I would like to personally thank the entire Aquasystems team for their friendship, hospitality, generosity, and for recognising the achievements of our team in such an unexpected and gracious manner. We accept the award with heartfelt gratitude.

Special thanks and acknowledgment are given to all end-users, consultants and contractors throughout Australasia who have purchased or specified the world-leading aquaturbo® surface aerator and have therefore contributed to this accolade.

Water is a hazard – wastewater is a greater hazard.

Gaining access to floating equipment on wastewater has the potential for harm so Aeris Global has developed a range of products to mitigate risk.

OTTERJETTY® – Safe Access Jetty
otterjetty® is a floating jetty purpose-designed to suit specific access requirements. A version is available to berth the otterpontoon® and an unlimited range of size options are available with work platforms. Otterjetty® is available as 3, 4, 6, 8, 9 & 12m long walkways to suit the water level variation or required reach.

OTTERDOCK® – Safe Docking Platform
otterdock® is a floating platform designed to reach out to deeper water, allowing aerators and mixers to be retrieved, and docked, without hitting the side-slope. Personnel can access equipment for inspection, preventive maintenance or crane connection without leaving the safety of the platform.

OTTERPONTOON® – Safe Access Pontoon
otterpontoon® is a self-propelled work platform providing personnel with a highly stable means of direct access to floating equipment. otterpontoon® is purpose designed for safe, efficient and hygienic operation with many features including 4-way access handrails, rescue rails, non-skid floor, bench seat, tool holders, 24V brushless drive, propeller guard and 240V battery management system.

OTTERBUOY® – Safe Access Sensor Float
otterbuoy® provides a safe and efficient means of mounting and accessing sensors in wastewater treatment ponds. otterbuoy® features a 6.5m swing-arm designed to extend over the side-slope to deeper water. otterbuoy® incorporates a trolley base and uses the side-slope as a ramp for launching and retrieving. Two stability cables double as draws lines for launch and retrieval.

Commencing 29 September, this year’s annual Water New Zealand Conference & Exhibition, will be hosted in Christchurch.

The event will be held at the world-class Te Pae Convention Centre located in the very heart of Christchurch city.

Te Pae is a replacement for the previous Convention Centre, demolished after the 2011 Christchurch earthquake.

The inner-city buss and seemingly endless choice of bars and restaurants surrounding Te Pae will make this conference a pleasure to attend as an exhibitor, delegate or visitor.

I will be joined on the stand by experienced team members Holly Byrne and Darrel Clark. Holly leads the project team and Darrel manages Field Services.

The latest addition to the Aeris Global Field Service fleet has just landed in NZ.

The hashtag#Scania G 500 B6x6 HZ was custom-built in Sweden to Aeris Global specifications. It features a 500hp Euro 6 engine coupled to a G33CM automatic gearbox and numerous options engineered at the factory specifically for off-road crane operation.

The rig will be fitted with a hashtag#Palfinger PK 370 TEC Knuckle Boom Crane with a lifting moment of 343.3kNm (35mt) and includes front and rear outriggers.

The crane features continuous slew and an impressive array of options including the proprietary HPSC (High Performance Stability) system developed by Palfinger. The system uses a “real data algorithm” to calculate the maximum lifting capacity at each point of the fully variable working range.

The truck and crane will be delivered to the highly experienced and capable hands of T. L. MacLean Limited in Mosgiel to couple the crane and construct the purpose-built deck.

The rig is expected to be complete by the end of November and will operate throughout NZ.

Its primary role is to deliver, assemble, install and service aerators, mixers, and decanters and safe access equipment; deliver and collect export and import consignments to and from port; transport portable site offices to worksites; backload materials from suppliers and perform miscellaneous logistics duties.

The latest product development from the Wanaka based Aeris Global design team is a 2nd generation version of the popular otterpontoon-Safe Access Platform.

Gen-2 is a “clean sheet” development with only the 24V drive and battery management system retained from Gen-1.

Gen-2 has a wide range of new features including 4-way access handrails, fore-and-aft shunting fenders, foldaway workbenches, tool and parts storage, deployable rescue rails, mooring cleats, closed cell polyurethane foam filled floats, increased payload and an integrated IP67 rated power connection port.

The first Gen-2 is destined for Fonterra Edendale and includes a tip-able, all terrain trailer, allowing it to be deployed in all four wastewater treatment ponds.

Proven performance at one site is often the catalyst for installation at others.

This has repeatedly proven to be the case with aerdisc® as one installation routinely leads to another.

All process industries are constantly in search of efficiency gains and none-more-so than wastewater treatment.

aerdisc® is achieving ground-breaking gains in terms of oxygen transfer efficiency, prevention of short-circuiting, rag-free operation and ease of access.

aerdisc® performance speaks for itself!

Quality is a choice. Leading organisations choose aerdisc®

At risk of stating the patently obvious, this message must be restated and
emphasised because hundreds of WWTP’s across Australasia are collectively burning millions of dollars of energy running low-efficiency aerators.

We visit many plants suffering from low DO and yet paying huge energy bills.
Aeration is central to aerobic wastewater treatment and is often the highest consumer of energy, therefore, efficient aeration is fundamental to reducing operational costs.

Aeration efficiency is measured in kgO2/kWh therefore every percentage INCREASE in efficiency is a percentage DECREASE in energy consumption.

An aerator with DOUBLE the efficiency of another will HALVE energy consumption. Alternatively, it can double the capacity of a plant for the same energy consumption.

Replacing out-moded aerators with modern, high-ef­ficiency aerators can dramatically reduce energy consumption and boost plant capacity.

Contact Aeris Global to discover how efficient aerators can reduce energy, increase plant capacity and extend plant life.

After only one month into a six-month aerdisc® trial at Forest Hill STP, Wagga Wagga City Council decided there was no reason to wait a further five-months and decided to buy two!

Aeris Global installed one aerdisc® in the Pasveer Ditch at Forest Hill and council observed immediate results in terms of improvements in ditch velocity and exceptionally low levels of spray.

After one month of operation the process improvements were so significant council decided to progress towards procurement of two aerdisc® aerators without further delay.

Beautiful and wastewater may not be words we use together in everyday conversation but for our Field Service Team it’s commonplace.

Some of the sites our team get to visit are simply stunning!

Interestingly, wastewater treatment plants are often located in the most picturesque settings. The images show some picture-perfect examples.

Western Bay of Plenty District Council and Aeris Global have completed contractual formalities for the Waihi Beach SBR Works Package.
The PDP designed Sequential Batch Reactor project incorporates aeration, mixing, decanting and safe access.

Aeris Global will provide the complete package of supply and services incorporating design, manufacture, and installation of the entire SBR Works Package.

The system includes 450kW of aquaturbo® Model AER-AS Floating Surface Aerators, 111kW of Model MIX-AS Floating Downdraft Mixers, one 1,500m3/h Floating Decanter and four otterdock®- Safe Docking Platforms.

The project is a perfect fit for the Aeris Global scope of supply and services. The Aeris Global Field Service Team will deliver, assemble, install and commission the entire package of equipment.

In keeping with the Aeris Global philosophy of providing the complete package, all proprietary installation accessories from the aercable® and aerisanchor® product ranges are also included.

Following a rigorous tender process Aeris Global is proud to have been awarded the contract to provide aeration upgrades to North East Water wastewater treatment plants.

The comprehensive project involves various sites across North-East Victoria and will incorporate a combination of aerdisc Directional Aerators and aquaturbo Surface Aerators.

North East Water serves an area of roughly 20,000 km2 with approximately 120,000 people in 39 towns with 22 wastewater treatment plants.

The first aerdisc® Directional Aerator was installed three years ago at Cromwell WWTP for Central Otago District Council.

As a fitting tribute to them, today the 100th aerdisc® was installed at their Roxburgh plant.

Five aerdisc® aerators are in operation at Cromwell and have proven to be a resounding success with exceptional oxygen transfer, elimination of short-circuiting, zero downtime, and not a fibre of rag on the discs.

aerdisc® is now operating in most NZ councils as well as multiple industrial sites.

The market uptake rate across the Tasman has been equally remarkable with over 30 units in operation across five states with many more in production, transit or pending.

Interestingly, the range of aerdisc® applications in Australia has been more diverse than NZ with installations including stormwater lagoons, Pasveer ditches and even IDEA basins.

The first quarter of 2025 has been a hectic time for the Aeris Global Field
Services Team with two major oxidation ditch projects occurring simultaneously.

The first two of four 132kW aquaturbo® AER-GD Low-speed Surface Aerators were installed at Mandurah, at the same time as the first two of six 160kW units were installed at Alkimos.

All aerators include the exceptional Hansen P4 Industrial Gearbox and WEG W22 Electric Motor.

Both projects feature the proprietary Aeris Global Aerator Mounting System. The Insertable Yoke proved invaluable for installing the impeller and Mounting Frame in combination.

Images show the process of lifting the impeller and Mounting Frame together followed by connection of the drive and removal of the Yoke.

Considering the total assembly weights over 6-tonnes, the Yoke made lightwork of an otherwise fiddly task.

The Insertable Yoke also allows disconnection and removal of the drive while the impeller remains in position but above the flow of water in the ditch.

The removable Mounting Frame allows installation and removal of the entire aerator while the plant remains online. The Mounting Frame creates a square opening in the endcap of sufficient size to allow the aerator impeller to pass through.

Wingecarribee Shire Council is currently upgrading the Mossvale wastewater treatment plant due to overloading.

They were struggling to maintain compliance during the upgrade process. Not surprising considering the existing plant was designed for 9,000EP (Equivalent Population) but is currently treating 16,000EP!

The two IDEA (Intermittently Decanted Extended Aeration) basins with a water level of less than 2.5m are installed with membrane diffusers, which were failing to meet the oxygen demand.

Ian Freere, Wastewater Treatment Supervisor for Wingecarribee Shire Council
investigated options for supplemental aeration during the upgrade process and recalled seeing the aerdisc® Directional Aerator at Ozwater’23 in Sydney so contacted Aeris Global Australia.

This was a unique application because it required an aeration technology able to operate above the existing membrane diffusers but without dislodging or damaging them and certainly not reducing their efficiency.

Aeris Global theorised the introduction of horizontal velocity using aerdisc® would not only provide supplemental aeration but would also improve the efficiency of the diffused air system.

aerdisc® is a directional aerator and typically operates in shallow water (<2.5m) so a strong discharge velocity is necessary to maximise the bubble dwell time.

In the absence of a horizontal velocity, bubbles exiting membrane diffusers will take a beeline to the surface so, correspondingly, bubble dwell time will be low and oxygen transfer efficiency poor.

Bubbles coalesce almost immediately without horizontal velocity and each doubling of bubble size results in a 400% increase in bubble rise rate!

Once again aerdisc® delivered the results by dramatically improving the performance of the plant within days.

aerdisc® is 100% rag-free!

Ragging is a bane in the life of every wastewater treatment plant operator.

When developing aerdisc®, we prepared a design brief and No.1 on the list was “Resistance to ragging”.

It was a lofty goal considering ANYTHING immersed in wastewater, or intercepting the flow of wastewater, is susceptible to ragging; more-so if moving and, worse-still if rotating.

aerdisc® is immersed 300mm, rotating at 69rpm and often installed in unscreened plants so should be highly vulnerable to ragging.

However, the unique disc design has no capacity to capture rag and in-fact repels rag and other debris due to the formation of a boundary layer at the periphery of each disc.

At Central Otago District Council’s Cromwell plant, five aerdisc® aerators have been operating continuously for almost 3-years in ponds, heavily laden with rag and settled deposits and yet there is not a fibre of rag on the discs.

We originally aimed for resistance to ragging but can now state, ELIMINATION of ragging.

Once again WIOA Bendigo has lived up to its reputation as the friendly show.

A constant stream of relaxed delegates, visitors and fellow exhibitors called in for a chat with the Aeris Global Australia Team.

We were proud to display the world-leading aquaturbo Surface Aerator, which celebrates its 50th anniversary this year.

Also on display was the groundbreaking aerdisc Directional Aerator including two full-size aerdisc rotors on the Aeris Global truck parked at the show entrance.

Thanks to everyone who visited us on the stand; past, present and future clients; old friends and new, we enjoyed your company.

The Victoria Water Industry Operations Conference & Exhibition will be held next week!

The relaxed vibe is a hallmark of all WIOA events, making them a pleasure to attend as an exhibitor, delegate or visitor.

Aeris Global is proud to be an exhibitor again at this years’ event.

I will be joined on the stand by experienced team members Holly Byrne and Darrel Clark. Holly leads the project team and Darrel manages Field Services.

If attending, please drop in for a chat at Stand 134.

The ability to deliver and install aerators at short-notice has been well received by municipal and industrial clients alike, and in some cases has proven a lifesaver.

Aeris Global currently has over 1,000kW of aquaturbo® Model AER-AS Floating Surface Aerators and 30 aerdisc® Directional Aerators in stock.

Many aeration projects also incorporate mixers, so the two fastest moving model variants have been added to the Aeris Global stock range; these being aquaturbo® MIX-AS 11kW and 22kW.

If your need is IMMEDIATE, we can delivery.

Yesterday, I was delighted to speak as part of the WIOG (Water Industry Operators Group) tour of Christchurch City Councils, Bromley Wastewater Treatment.

Last week Aeris Global installed its FIRST aerator in the Oxidation Ponds at Bromley. After less than a week of operation the aerdisc Directional Aerator is already impressing many observers including the WIOG visitors.

Aeris Global was not involved with the supply or installation of any other aerators in the Oxidation Ponds.

However, we were intimately involved with other aspects of the plant following the tragic fire in 2021, which destroyed two trickling filters.

I was asked to speak about our contract to convert two of the plants 49m diameter clarifiers into high-energy aerobic reactors by installing 600kW of aquaturbo surface aerators.

In technical terms, this was not a particularly challenging project but logistically, it was near impossible!

The fire occurred on 1 Nov 2021, and we were awarded the contract on Christmas Eve, but only on the condition the plant was fully operational by 31 Mar 2022.

Multiple key suppliers were asked to slash normal lead-times in the interest of supporting a council in crisis.

14-tonne of equipment was airfreighted from various locations in the world at a total cost of over $600,000!

True to our word, the plant was commissioned on 31 Mar 2022.

This week the Aeris Global Field Services Team installed an aerdisc® Directional Aerator at Bluff for Invercargill City Council. Bluff is the Southernmost wastewater treatment plant in mainland New Zealand.

As well as being world famous for its oysters, Bluff, or Stirling Point to be exact, marks the Southern end of State Highway 1.

The Bluff Hill Climb is one of the most gruelling stages on the Tour of Southand and to win it is regarded as a huge achievement and a highlight in the career of any cyclist.

The aerdisc® installation pic shows Bluff Hill in the background and the landscape pic shows the view from Bluff Hill lookout.

aerdisc® has proven its diversity in terms of process applications but is also delighting end-users with a seemingly endless array of mooring options.

The unique multi-directional, A-Frame swing-arm can be attached to any one of three positions on the pontoon to suit to the required vector-of-thrust: Inline, Lefthand or Righthand.

After selecting the desired configuration, the exact vector-of-thrust can be adjusted over a wide range of angles.

If requirements change, an alternative configuration can be selected at any time.

The aerdisc® swing-arm is designed to allow the aerator to swivel to the berm for inspection, housekeeping or crane connection.

Lifting the aerator does not require swing-arm or electrical disconnection.

Tension Cables are used when a remote installation or extreme water level variation does not allow use of the preferred swing-arm mounting system.

Linkage Arms are used for installation in a Pasveer Ditch or other narrow channel applications. The Linkage Arms pivot to suit water level variations.

Please enquire about our trial units for lagoon, ditch, IDEA or any other application you can think of.

If you have a site where low DO, odour, ragging, or short-circuiting is a problem, please consider trialling an aerdisc® and evaluating the results on a try-before-you-buy basis.

Aeris Global Field Services will mechanically install the trial aerator. At the conclusion of the 6-month trial the host will have the right to purchase, but not the obligation.

Last week I joined the team to travel around Northland as part of the aerdisc® nationwide roadshow and we were blown away by the place.

Not only by the breathtaking sunsets and scenery but also by the amazing hospitality we were shown along the way.

Grassroots New Zealand is truly a special place. Made me proud to be a kiwi!

The sunset pics show the view from our hotel in Ōmāpere. Absolutely awe-inspiring!

It was a balmy night, so we sat on the beach till well after dark.

aerdisc® is only one product but is proving to have the diversity of many.

Regardless of where aerdisc® is installed, it has the uncanny ability of getting the job done.

Lagoon installations on both sides of the Tasman are plentiful with applications many and varied.

More recent additions to the growing range of applications are Pasveer Ditch and IDEA basins.

Last year Shoalhaven Water installed the first two aerdisc® aerators in a Pasveer Ditch at their Vincentia plant.

Earlier this year South Burnett Regional Council in Queensland installed an aerdisc® at their Nanango WWTP.

Both installations have been a great success.

The latest example of aerdisc® diversity is at Wingecarribee Shire Council, where one unit was installed in an IDEA (Intermittently Decanted Extended Aeration) basin at Mossvale STP.

The unique application involved the aerdisc® operating above the existing membrane diffusers, which were failing to meet the oxygen demand.

One again aerdisc® delivered the results by dramatically improving the performance of the plant within days.

Please enquire about our trial units for lagoon, ditch, IDEA or any other application you can think of.

Countries such as New Zealand and Australia have land, so we tend to construct horizontally, because it’s less expensive. Shallow, multi-hectare lagoons are commonplace for us. More densely populated countries prefer a smaller footprint so tend to construct vertically.

New Zealand has 330 council operated wastewater treatment plants and Australia has 720, giving a total of 1,050 plants.

Industrial wastewater treatment plants throughout the region greatly increase this number.

Many of these plants include lagoons, in some form, and many of those have an oxygen demand. This demand is met by natural and/or mechanical aeration. As flow and loadings increase, oxidation, stabilisation, and facultative lagoons are often converted from natural to mechanical aeration.

Most lagoons in New Zealand and Australia are earthen constructed with clay liners. However, an increasing number are constructed with membrane liners or retrofitted with membrane.

Often, the lagoons are unscreened, and many are laden with settled deposits. This is slowly changing in accordance with availability of funding for new headworks and regular sludge dredging.

To function and perform effectively in this environment an aerator must have high oxygen transfer efficiency; a strong horizontal discharge with a high pump rate to prevent short-circuiting, but with no risk of damaging fragile clay liners; the ability to operate in totally unscreened lagoons without ragging, even when overloaded with settled deposits.

aerdisc® was specifically developed by Aeris Global to fill the need for an efficient, shallow water directional aerator because little work had been done in this design space for decades.

Last week, Aeris Global was delighted to host senior executives from SFA-Enviro companies in France, Belgium and the USA.

SFA-Enviro incorporates Aquasystems International in Belgium and Aquaturbo Systems in the USA; manufacturers of the world-leading aquaturbo product range. SFA-Enviro forms part of the giant, Paris based SFA Group.

The attached picture, taken at Lake Pukaki shows, from right to left, Aurélien Goyeau, CEO of SFA-Enviro; Elke Lemmens, COO of Aquasystems International; Miguel Perez, COO of Aquaturbo Systems and Bruce Henley, MD of Aeris Global.

The remarkable, glacial fed, Lake Pukaki turns a beautiful turquoise colour as sunlight is absorbed and scattered by the glacial silts. The silt, known as glacial flour, is so fine it remains in suspension and therefore exposed to the sun’s rays.

Last Wednesday was a perfect opportunity to showcase this phenomenon as the Mackenzie Country turned on a glorious day. Lake Pukaki is one of the top three clearest waters in the world.

Thanks, from all the team at Aeris Global Limited in Wanaka and Aeris Global Australia Pty Limited in Melbourne for a sensational 2024!

The two companies have completed a record volume of projects and have been awarded a record volume of new contracts for the 2024 calendar year.

2025 has kicked off the same way 2024 ended, so looks set to eclipse all past years.

aquaturbo remains the world’s leading mechanical aeration brand and the Aeris Global designed and manufactured aerdisc Directional Aerator is taking the world by storm.

We wish all clients, consultants, contractors, partners and colleagues a successful 2025.

Last week, Aeris Global installed another aerdisc® Directional Aerator in a Pasveer Ditch. This time at Nanango WWTP for South Burnett Regional Council in Queensland.

aerdisc® was developed primarily for pond-based treatment processes but has proven equally adept for Pasveer Ditch applications.

Last year Shoalhaven Water installed the first two aerdisc® aerators in a Pasveer Ditch at their Vincentia plant and were impressed by the performance.

Upon startup the results were virtually immediate with a dramatic increase in ditch velocity.

In the following days operators determined the aeration time could be halved in accordance with the superior oxygen transfer efficiency of aerdisc®.

Judging by the Nanango video shared with this post, aerdisc® seems certain to impress again.

Please enquire about our trial units for pond and ditch applications.

If you have a site where low DO, odour, ragging, or short-circuiting is a problem, please consider trailing an aerdisc® and evaluating the results on a try-before-you-buy basis.

Aeris Global Field Services will mechanically install the trial aerator. At the conclusion of the 6-month trial the host will have the right to purchase, but not the obligation.

The West Coast turned on a picture perfect, bluebird day for the Aeris Global Field Service Team to install an aerdisc® for Buller DC at their Reefton WWTP.

In December 2023, the ADC’s Oxidation Pond faced a critical need for aeration improvement. The pond was experiencing short-circuiting, stagnant zones, low oxygen levels, and a high risk of the pond flipping.

Aeris Global responded quickly by installing three aerdisc® directional aerators. Before installation, DO levels were critically low at 0.3 to 0.5 mg/L. Within days DO levels rose to 2 to 5 mg/L, pond circulation and health were transformed.

Following the success of the Oxidation Pond, council made the decision to replace all ten 7.8kW aerators (78kW) in the lifeless Aeration Pond, which ran 24/7 and struggled to achieve a DO above 0.1 mg/L.

After the installation of four aerdisc® aerators with a total energy of only 30kW the change was significant within days. The Dissolved Oxygen increased from 0.1 to 2.55 mg/L, complete mix conditions were restored, and short-circuiting was eliminated.

“aerdisc brought our ponds back to life. We’ve seen a major improvement in DO levels, no short-circuiting, better sludge distribution, and the removal of noxious odours – results that exceeded our expectations.”

Nathan Harvey, Projects and Compliance Engineer, Ashburton District Council

In past years’ we have received mayday calls in November and sometimes even December from Local Government Authorities looking for aerators to allow their plants to cope with increased seasonal loadings.

Aeris Global currently has over 1,000kW of aquaturbo® Model AER-AS Floating Surface Aerators and 30 aerdisc® Directional Aerators in stock.

All equipment is available on short lead-time for emergency requirements.

If your need is urgent, our team can deliver!

Why do Aeris Global safe access product names start with otter?

OTTERDOCK® – Safe Docking Platform

OTTERPONTOON® – Safe Access Pontoon

OTTERJETTY® – Safe Access Jetty

OTTERBUOY® – Safe Access Sensor Float

The Otter is one of only few creatures in the animal world to use tools, but they go one step further than any other.

Otters float on their back using their body as a workbench. They are notable for their ability to use stones as tools to break open shellfish and sea urchins on their stomachs.

The Otter is one of mother natures’ great innovators and one of the toughest.

We are very proud for our safe access products to bear the Otter name.

Tradeshows certainly do require a big effort but they’re also a great opportunity for the team to have some fun.

The Water New Zealand Conference & Expo in Hamilton last week was no exception.

Just because they could, the engineering team in Wanaka built a half-scale aquaturbo® Model AER-AS aerator out of MDF and multiple 1/10th scale giveaway models. Both versions attracted a constant stream of interest.

The beer tasted good after the stand was complete and the aerdisc® aerator assembled on the front lawn.

This image shows an aerdisc® operating at Ruapehu District Council’s Ohakune WWTP. It has not missed a beat since installation in 2022.

It clearly illustrates aerdisc® in a nutshell.
–     Outstanding oxygen dispersion
–     Negligible spray
–     Zero ragging
–     No backflow

The Lateral Spar spanning between the floats is a key design feature of aerdisc® because it performs multiple functions. It literally is the backbone of the pontoon structure because it allows a completely open discharge, while countering the thrust generated by the aerator in operation. The Lateral Spar also allows each float to move independently of the other, during startup and operation, while remaining perfectly parallel.

The countdown has begun for this years’ Water New Zealand Conference & Expo commencing 25 September at Claudelands, Kirikiriroa Hamilton.

The removable Mounting Frame allows installation and removal of the aerator while the plant remains online. The Mounting Frame creates a square opening in the endcap of sufficient size to allow the aerator impeller to pass through.

Enclosed endcaps on oxidation ditches are intended to contain aerosols and prevent odour migration but in-doing-so they can limit the supply of atmospheric gases, particularly if lane curtains are installed in the opening between the endcap and the water level. Surface aerators require a continuous supply of air to function effectively.

The Aeris Global Mounting System includes four lamella plate cassettes allowing unrestricted supply of air to feed the aerator impeller but prevent splash from escaping.

Upon removal, the entire assembly is placed on a Support Platform, purpose-designed to accept the Mounting Frame. Following placement, unrestricted access to the aerator is available for personnel to perform tasks such as disassembly, inspection, adjustment and maintenance.

An insertable Yoke allows the drive to be disconnected and removed while the impeller remains in position but above the flow of water in the ditch.

Aeris Global® has manufactured the Aerator Mounting System for aquaturbo® AER-GD aerators in multiple sizes from 22kW to 160kW. 220kW and 300kW versions have been recently developed for a project in West Australia.

Aeris Global use and recommend Hansen Industrial Gearboxes and WEG Electric Motors.

So far, 13 Utilities in the North Island have 28 aerdisc® Directional Aerators either in operation, or in progress

8 of the 28 units were provided as part of the 2022 Nationwide Local Government Pilot Study; 4 others were provided for subsequent trials; 16 units were purchased outright.

So far, 12 of 19 District Councils in the South Island have aerdisc® Directional Aerators either in operation, or in progress.

Just 26-months after the first aerdisc® installation for Central Otago District Council at their Cromwell WWTP, South Island local government projects have grown to 27 with many others pending.

4 of the 27 units were provided as part of the Nationwide Local Government Pilot Study; 6 others were provided for subsequent trials. 17 units were purchased outright.

Many wastewater treatment plants suffer from the same issues: high-energy, low-effi­ciency aerators, poor mixing, and short-circuiting.

Replacement of out-moded aerators with modern, high-ef­ficiency aerators can dramatically reduce energy consumption and boost plant capacity.

Prevention of short-circuiting can provide the greatest improvement in process performance.

Together, ef­ficient aerators and short-circuit prevention can increase plant capacity and extend plant life, delaying or even avoiding the need for new construction.

Contact Aeris Global to discover how advanced aerators can extend the life of your WWTP.

Just 2-years after the first Pilot Study aerdisc® was installed at the Cromwell Wastewater Treatment Plant, New Zealand installations, currently, exceed 70 with new projects being added at an increasingly rapid rate.

Aeris Global allocated 14 units for the nationwide local government Pilot Study and all 14 units were purchased by the host site.

The Pilot Study concept has proven to be a very effective means of trialing a new technology because the Pilot Study partner had the right to purchase, but not the obligation.

The Pilot Study provided the host with the opportunity to prove the effectiveness of the product and its suitability for their application during the 6-month Pilot Study period, so it effectively removed all forms of risk.

As we visit pond-based wastewater treatment plants throughout Australasia, we see the same issues at multiple sites:
–     High-energy, low-efficiency aerators
–     Poor mixing and short-circuiting

Many plants are suffering from low DO and yet paying huge energy bills.

Retiring end-of-life or outmoded aerators and replacing with modern high-efficiency aerators can dramatically reduce energy consumption and boost plant capacity.

Short-circuiting can also have a huge impact on the performance of any flow-through pond system because it equates to a reduction in process volume. Prevention of short-circuiting can provide the single greatest jump in process performance.

The combined effect of efficient aerators and prevention of short-circuiting will increase plant capacity and can extend plant life.

Increased capacity can delay and, in some cases, avoid construction of new plants.

Seven aerdisc® Directional Aerators have been installed at Ashburton District Councils, Wilkins Road Wastewater Treatment Plant over the last three months. Three in the oxidation pond and four in the aeration basin.

Previously, the aeration basin had Qty 10 x 7.5kW incline-shaft aerators, each including a side-channel blower, for a total energy of over 80kW, but even so the plant continually suffered from low DO and major short-circuiting issues.

Upon installation of only four 7.5kW aerdisc® aerators with a total energy of only 30kW, the DO jumped and short-circuiting was eliminated.

Two-years on from installation in June 2022 aerdisc® continues to impress with zero downtime.

aerdisc® replaced equipment with extremely low oxygen transfer efficiency and exceptionally high-power consumption. It also proved unreliable, expensive to maintain and prone to ragging.

The original system consisted of fifteen diffused air bubblers, arrayed around the edge of the two ponds. Each unit was fitted with two side-channel blowers. The total energy consumed by the thirty blowers was 93kW!

The bubblers were unable to lift the DO above 0.2mg/L, even with all 93kW in operation.

By comparison, five 7.5kW aerdisc® aerators, with a total energy of only 37.5kW, easily meet the oxygen demand with capacity to spare.

Within 24-hours of the first aerdisc® starting in Pond 1, the DO climbed to 2.5mg/L. After the second unit came online the DO jumped to 5mg/L and continued to rise until control was introduced.

Disaster struck Christchurch City Council’s Bromley WWTP in November of 2021 when fire destroyed two trickling filters.

As an interim emergency response council elected to convert two of their 49m diameter clarifiers to high-energy, aerobic reactors and awarded the contract to Aeris Global.

Aeris Global installed 600kW of aquaturbo® AER-AS Floating Surface Aerators consisting of four 75kW units in each clarifier.

The system was commissioned in March 2022 and has not missed a beat since, with the ultra-reliable aquaturbo® aerators achieving the distinction of 100% availability for duty.

We often describe aquaturbo® Model AER-AS as the world’s leading direct-drive surface aerator and this project is proof-positive the claim is justified.

To this day, nothing aerates like aquaturbo®

The latest offering from the Aeris Global design team is otterbuoy®, a pond-friendly sensor float.

The product development is in response to enquiry from clients seeking a safe and efficient means of mounting and accessing sensors in wastewater treatment ponds.

Sensors are easy to mount and access in tanks with vertical walls but less so in earthen constructed ponds with side slope, where water is shallow at the edge.

otterbuoy® features a 6.5m swing-arm designed to extend into the pond and therefore reach out to deeper water. The swing-arm is positioned using two stability cables.

Rather than seeing the side slope as an obstacle Aeris Global engineers elected to use it as a ramp for launching and retrieving otterbuoy®.

otterbuoy® incorporates a trolley base with three-wheels orientated to match the arc scribed by the swing-arm when traversing up or down the side slope. The two stability cables double as draws lines for launch and retrieval.

Last week, Aeris Global Field Services installed two aerdisc® Directional Aerators in a Pasveer Ditch at Vincentia STP for Shoalhaven Water.

The journey started when Shoalhaven Water personnel visited Aeris Global at the WIOA Conference in Canberra last November.

aerdisc® was developed primarily for pond-based treatment processes but when approached by Shoalhaven Water about the potential for utilisation in a Pasveer Ditch it warranted investigation.

Aeris Global engineers determined aerdisc® would physically fit in the Vincentia ditch and only minor modifications would be required to replace the standard swingarm with a cable mooring system.

Upon startup the results were virtually immediate with a dramatic increase in ditch velocity compared to the three adjacent ditches.

In the following days operators determined the aeration time could be halved due to the superior oxygen transfer efficiency of aerdisc®.

Please enquire about trial units for pond and ditch applications. If you have a site where low DO, odour, ragging, or short-circuiting is a problem, please consider trialing an aerdisc® and evaluating the results on a try-before-you-buy basis.

Aeris Global Field Services will mechanically install the trial aerator. At the conclusion of the 6-month trial the host will have the right to purchase, but not the obligation.

To secure an aerdisc® for your wastewater facility please reach out to Holly Byrne, our aerdisc® Trial Program Coordinator, at holly@aeris.global

The latest stock order of aquaturbo® surface aerators and downdraft mixers will arrive this month.

The trial, last year, involving increased stock levels of aquaturbo® surface aerators has been extremely well received by the industry and, in some cases, has proven to be a lifesaver.

The initiative to carry more stock is intended to ease the impact of long manufacturing and shipping lead-times.

The aquaturbo® AER-AS surface aerator stock range includes 22, 30, 37, 45, 55 and 75kW model variants.

Many aeration projects also incorporate mixers, so the two fastest moving downdraft mixer model variants have been included in the latest stock order; these being aquaturbo® MIX-AS 11 and 22kW.

Aeration energy often accounts for the greatest consumption of electricity in a wastewater treatment plant.

Aeration equipment with poor efficiency accounts for the greatest waste of electricity in a wastewater treatment plant.

Inefficient aerators can commit end users to decades of excessive power consumption because often there is a reluctance to retire equipment whilst it remains serviceable.

Enormous power savings are achievable when modern, high-efficiency aeration technologies are introduced.

aerdisc is often three or four times more efficient than the outmoded equipment it replaces.

Oxygen transfer efficiency is measured in kgO2/kWh, so every percentage gain in efficiency equates to the same percentage reduction in electricity consumption.

Two recent posts describe energy savings of 72% at Waitaki DC and 68% at Central Otago DC. Even more remarkable is the dramatic increase in DO and overall plant performance, whilst achieving the energy savings.

Aeris Global Australia Pty Ltd will celebrate opening of the Melbourne office by exhibiting at Ozwater’23 in Sydney.

The exhibition will include the Australian launch of aerdisc® Directional Aerator and will feature the aquaturbo® AER-AS Floating Surface Aerator.

The nationwide aerdisc® Pilot Study in New Zealand has been a resounding success with 100% of completed trials resulting in the partners purchasing the trial aerators, and many purchasing in multiples.

The unique capabilities of aerdisc® make it a gamechanger for lagoon aeration. aerdisc® sets new standards of oxygen transfer, resulting in massive energy savings; has no capacity to rag, nor scour the floor of earthen lagoons, and is purpose-designed to prevent short-circuiting.

aquaturbo® AER-AS Floating Surface Aerator is undoubtedly the world’s leading direct-drive surface aerator and has been since it was designed 48-years ago by Belgium based, Aquasystems International NV. The unique and easily identifiable horizontal discharge is as relevant today as it was at the time of its creation. To this day, nothing aerates like aquaturbo®!

In 2017 Central Otago District Council upgraded their Cromwell oxidation ponds. This included installation of fifteen aerators. Over the years these proved ineffective and resulted in low dissolved oxygen being recorded in the ponds almost all year round.

The equipment had extremely low oxygen transfer efficiency and exceptionally high-power consumption. It also proved unreliable, expensive to maintain and prone to ragging.

The system consisted of fifteen diffused air bubblers, arrayed around edge of the two ponds. Each unit was fitted with two side-channel blowers. The total energy consumed by the thirty blowers was 93kW!

Upon takeover by Fulton Hogan, CODC’s operations contractor, it was apparent the bubblers were unable to lift the DO above 0.2mg/L, even with all 93kW in operation.

Considering the situation, Aeris Global offered to provide CODC with two 7.5kW aerdisc® Directional Aerators as part of a nationwide Pilot Study, which was about to commence, even though all other plants were provided only one aerdisc®.
CODC duly accepted the offer and during June 2022 the units were installed, and the 6-month Pilot Study commenced.

Within 24-hours of the first aerator starting, the DO climbed to 2.5mg/L. After the second unit came online the DO jumped to 5mg/L and continued to rise until automated control was applied.

Ian Evans, Water Services Manager, Central Otago DC comments as follows:

“We have had two 7.5kW aerdiscs running in our primary pond at Cromwell for seven months. Dissolved oxygen levels have increased significantly, and we have seen no evidence of ragging on the discs even though the plant has been running without an efficient inlet screen for some time. At the end of the trial, we purchased the two aerators and ordered an additional three: four duty and one standby. We are confident these will provide us with all aeration requirements moving forward”.

 February has been a busy month for the Aeris Global Field Services Team with three combo projects reaching commissioning phase.
 
All three projects feature aquaturbo® equipment along with proprietary otterdock® Safe Docking Platforms. otterdock® allows personnel to retrieve, and access, equipment from the safety of the platform, rather than going on the water.

Thomas Prins, the Operations Supervisor, at Waitaki District Council is impressed with the performance of aerdisc® Directional Aerators; the first installed as part of the nationwide Pilot Study, and the second as an outright purchase:
 
“The aerdisc® aerator installed at Palmerston WWTP has significantly increased the DO even when operating only at night. Our old cage aerators were running 24/7. The plant is unscreened, but the aerator does not rag up at all, on any moving parts.
 
The bearings are sealed and do not require any maintenance. The swivel mounting bracket makes it very easy to pull the aerator to the side of the pond for access.
 
The second 7.5kW aerdisc® purchased for one of our larger oxidation ponds at Oamaru WWTP has allowed us to remove one of our old 27kW aspirator aerators.”
 
Both aerdisc® aerators are performing above expectations”.

2023 is a huge Year for Aeris Global on both sides of the Tasman.

Aeris Global commissioned the 600kW system last week as an emergency response following a tragic fire at the plant last November, which destroyed two trickling filters.

As an interim solution Christchurch City Council elected to convert two of their 49m diameter clarifiers to high-energy, aerobic reactors and awarded this contract to Aeris Global.

Aeris Global has previously acknowledged the tremendous support provided by Aquaturbo Systems, WEG, and TR Industries, which made this project possible in the extraordinarily tight time-frame but in this post, we would like to acknowledge the client.

The commitment by council and their advisors to fast-track this project was outstanding. The decision-making and expedited approval process is a credit to all involved.

Following the devastating fire at Bromley WWTP last November, council elected to convert two of their 49m diameter clarifiers to high-energy, aerobic reactors.

Aeris Global was awarded the contract in December on the proviso the system was operational by the end of March.

The contract includes design, supply, and installation of a 600kW emergency aeration system consisting of eight 75kW aquaturbo® Model AER-AS Floating Surface Aerators along with a proprietary aercable® Safe Access, Cable Management System.

With exceptional support from Aquaturbo Systems, WEG, and TR Industries, Aeris Global successfully delivered the equipment to site in February!

The logistical challenge involved airfreighting 14-tonnes of equipment from USA, Brazil and Australia with numerous ancillary components coming from NZ suppliers or manufactured by Aeris Global in Wanaka.

Aeris Global Field Services installed the system this week.

The latest product development from Aeris Global commenced full-scale field trials yesterday on a picture-perfect Wanaka day.
 
The Field Services crew tested the pre-production aerdisc® in perpendicular and inline configurations and it performed without a hitch.
 
Production of 15 x 7.5kW aerdisc® aerators for the nationwide local government Pilot Study can now commence.
 
The 15 units will be installed at 13 host sites throughout New Zealand and will run for 6-months.

Stage One of the response involves the conversion of two 49m diameter clarifiers into high-energy reactors.

600kW of 75kW aquaturbo Model AER-AS Floating Surface Aerators will be installed with two coming from Aeris Global stock in NZ and the other six being manufactured by Aquaturbo Systems Inc. USA.

When made aware of the crisis, the Arkansas based aeration specialist kindly agreed to come to the aid of Christchurch City. They jumped production of the aerators to the front of the cue and agreed to continue work through the festive period with completion scheduled for mid-January.

Brazil based WEG, and local partners TR Industries, also leapt to support the city by expediting the production of electric motors for the aerators.

14-tonnes of equipment will be airfreighted to NZ during January in readiness for installation and commissioning in February by the Aeris Global Field Services team.

Injection mould tooling for the 60-degree disc segment is on schedule for commencement of mould trials next month. The tool, weighing over 1,800kg, is through the preliminary stages of the build and is due to start bench core and bench cavity stages this week.

Six interconnected segments form a 1,000mm diameter disc and key to a tubular shaft via laser cut penetrations to control the disc spacing and pattern.

The unique disc shape is engineered to maximise the potential to collect and release air as well as generate horizontal velocity.

The operating principle involves a continuous cycle of harvesting atmospheric gases and dissolving oxygen as the partially immersed disc rotates.

aerdisc^® is designed for connection to a swing-arm using any one of three configurations to control the vector of thrust.

2021 marks 18-years of continuous partnership between Belgium based Aqua Turbo Systems Group and Aeris Global. Aeris Global represents the interests of Aqua Turbo Systems Group for Australasia, in association with Australia based Green Process.

The relationship spans from sole ownership by founder, Johny Haegeman, through to his sale of the company to Paris headquartered SFA Group in 2019.

Mr Haegeman designed the flagship aquaturbo AER-AS Surface Aerator over 40-years ago. The product is now in operation throughout the world and is internationally regarded as the market leader; an accolade he remains very proud of.

Aeris Global has developed many friendships within the worldwide team of Aqua Turbo branches and partners and looks forward to continuing the relationship for many years to come.

Does it suffer from oxygen deficiency; poor oxygen dispersion and mixing; odour and noise problems?

There are many reasons why an aeration upgrade may be necessary, but typically involve one or more of the following:

– Oxygen shortfall may be a result of existing aerators being outmoded or inoperable.

– Perhaps the flow and loading’s have increased and now exceed the design capacity of the plant.

– Or maybe seasonal or diurnal peaks have changed.

An aeration upgrade can provide multiple benefits:
1. Increase aeration capacity often without increasing energy
2. Extend plant life or delay expansion
3. Reduce maintenance and downtime
4. Reduce noise and odour

Aeration upgrades can almost always be installed whilst the plant remains online.

Aeris Global will work with your preferred consultant, operations contractor or directly with the end-user.

Aeris Global provides a full range of field services.

The latest product development project by the Aeris Global design team is a hand winch for retrieval and repositioning of floating aerators and mixers.

The project is driven by an ongoing desire to mitigate risk of personal harm by reducing the physical effort required to move equipment.

The product features an injection moulded reel with integral ring gears on each side. One side provides a 3:1 ratio and the other side allows further reduction to drive an auto-spooling device to evenly lay cable on the reel. Both planetary drives incorporate injection moulded planet gears but operating in different planetary configurations: static carrier on one side and rotating carrier on the other.

It is designed for attachment to the aerisanchor- Multi function Mooring System and to davits mounted on the otterdock – Safe Docking Platform.

The product is currently undergoing load and destruction tests at the Aeris Global test facility at Wanaka.
