Alexandra’s Wastewater Treatment Plant: Aeration and Mixing Upgrade

Central Otago DC, Alexandra Wastewater Treatment Plant, Aeration and Mixing Upgrade project is up and running.

Aeris Global designed and manufactured the system incorporating five Aquaturbo Model AER-AS Floating Surface Aerators with fully-articulated swing-arms and two bridge-mounted Wilo Submersible Mixers. The swing-arms allow each aerator to rotate to the wall for ease of access. Each aerator and mixer operates through a variable frequency drive to provide infinitely variable tapered aeration around the annulus.

The upgrade was carried out in association with the exceptional team at Fulton Hogan Central.
