WEST AUSTRALIAN LOW-SPEED AERATOR PROJECTS PROGRESS AT PACE

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.
