The SBR process consists of two reactor tanks with a common inlet system. The bio-selector at the influent section contains baffles to mix the reactor content and enhances digestion. The treatment step is followed by a settling phase, which runs parallel with the filling and aeration of the second tank. The treated water is discharged and the solids are extracted at the reactor bottom. ...

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 removed at the bottom. The major part of the biomass is ...

In membrane bioreactors ultrafiltration (UF) or microfiltration (MF) membranes are used for separation of the treated water from the mixed liquor (ML). The UF/MF membranes guarantee a constant and very high effluent quality as particulate matter (SS, microorganisms) cannot pass through the membranes. Furthermore, MBR installations require less space than conventional activated sludge systems ...
