There are various ways to deliver air to a secondary wastewater treatment process. Some involve blowers feeding diffusers on the bottom of a basin. Others are mechanical, introducing air through a stirring action.
Now Aqua-Aerobic Systems offers OxyStar aspirating aerators for municipal and industrial wastewater applications. Rated at 3 to 30 hp, they can be used to deliver oxygen and mixing to oxidation ditches and also to lagoons, aerobic digesters and equalization basins.
The units provide efficient fine-bubble aeration by circulating and mixing basin or tank contents. They are well suited for retrofit in process upgrades or to supplement or replace aeration systems
