Wastewater and Water Aeration Systems- CLEAN-FLO

Our wastewater aerators have a unique design that allows us to achieve high-capacity water movement with aeration, even in the winter. In designing our first wastewater aeration system, we tackled all of the toughest problems. Because of the energy crisis, the wastewater aerator had to be the finest bubble bottom diffuser available.

Wastewater Technology Fact Sheet: Sequencing Batch Reactors

Cycle Extended Aeration System (ICEAS). In the ICE AS system, influent wastewater flows into the reactor on a continuous basis. As such, this is not a true batch reactor, as is the conventional SBR. A baffle wall may be used in the ICEAS to buffer this continuous inflow. The design configurations of the ICEAS and the SBR are otherwise very similar.

Why is Aeration Important for Wastewater Treatment?

A well designed aeration system has a direct impact on the level of wastewater treatment it achieves. An ample and evenly distributed oxygen supply in an aeration system is the key to rapid, economically-viable, and effective wastewater treatment. The Membrane Aerated Biofilm Reactor is a game changer for wastewater treatment.

Activated Sludge Treatment Process Concept and System

Kraus process The Kraus process is a variation of the step aeration process used to treat waste-water with low nitrogen levels. Digester supernatant is added as a nutrient source to a portion of the return sludge in a separate aeration tank designed to nitrify. The resulting mixed liquor is then added to the main plug-flow aeration system. 85 -95
