Conventional Activated Sludge System

by Biothane - Veolia Water Solutions & Technologies

The conventional activated sludge system comprises an aeration tank and a clarifier. Aerobic biomass degrades COD in the aeration tank. The mixed liquor (ML) in the clarifier is separated into a water phase and a concentrated ML by sedimentation. The clarified water overflows weirs at the top of the clarifier whereas the sludge (biomass) is ...

Aqua - Activated Sludge-Water Separation System

by Aqua Industrial Watertreatment B.V.

For the final step in the biological treatment of wastewater, the separation of bacteria from the purified water, AQUA Industrial Watertreatment disposes of three different systems.

Sludge Centrifuge

by Morselt Borne Ltd
