Diffused Air Aeration

Diffused Air Aeration

Aerobic micro-organisms in the Activated sludge process require air for the digestion of organic matter. Depending on the application specifics either fine bubble or coarse bubble diffusers are used to discharge the required air below the water surface. Next to conventual activated sludge plants aeration diffusers are also used in SBR (sequencing batch reactor), CSR (Continuously sequencing reactors) and BNR (Biological nutrient removal) systems.

AET provides consulting and product solutions
for diffused air aeration systems.

Retrievable diffuser systems

The Jaeger-aeration retrievable strip diffuser rack systems provide a multi-level system redundancy and a fast and easy way to maintain diffusers without basin dewatering. The diffuser racks can be designed for any tank geometry (rectangular, round, toroidal) and mounted to basin walls as well as bridges or catwalks. Better oxygen transfer of fine bubble strip diffusers and DO load dependent air supply decrease overall power costs by up to 25%.
