Surface aerators – Dairy wastewater – New Zealand
Biological process dairy effluent aeration.
Lagoon 24.7 m x 17.2 m
Liquid level 1.75 m
SOTR 76 KgO2/h
The lagoon has a geomembrane lining.
Two AGV 400 – 30 kW high-speed surface aerators, with anti-erosion kits, offer the optimal solution given the shallow depth of the lagoon. The anti-erosion kit makes it possible to prevent vertical flow, which could disturb the geomembrane.
The aerators are controlled by way of an inverter, to modulate electricity consumption and oxygen yield.
