WebOct 1, 2024 · A membrane bioreactor is an adaptation of the conventional or classical activated sludge (CAS) process. The CAS process comprises a biological tank, in which aerobic treatment takes place to bio-degrade the organic carbon and amino compounds, followed by a sedimentation tank (secondary clarifier). WebAn oxidation ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Oxidation ditches are typically complete mix systems, but they can be modified to approach plug flow conditions. (Note: as conditions approach plug flow, diffused air must be used to ...
WebThe activated sludge process will often remove 85 to 95% of the BOD from the aeration influent. Activated sludge processes may or may not follow primary treatment. The need for primary treatment is determined by the process modification selected for use. All activated sludge systems include a settling tank following the aeration tank.
