A food company in Victoria has gone safety first by installing a Venturi aerator instead of surface mounted aerators. Because of this, operators can maintain the equipment quickly, easily and safely instead of having aerators floating in the lagoon [requiring boats, cranes or floating walkways to access].
They did not have to sacrifice efficiency either, as Venturi aerators can produce as much as 1.86kg/kWh of dissolved oxygen.
Venturi aerators are “powered” by Gorman-Rupp “bank mounted” pumps that accelerate pumped fluid through the Venturi aerator [V-A]. The V-A creates a venturi effect, drawing in atmospheric air. Air and pumped fluid are mixed together under pressure. The turbulent mixing facilitates the removal of soluble CO2 gas and reduces the size of volatile solids. Discharged water is saturated with dissolved oxygen.
