Sequential Batch Reactor (SBR)

SBR, if compared to the conventional activated sludge system, is capable to handle higher loading fluctuation, easy operation, compact layout, and most importantly, its capability to consistently producing high quality effluent. SBR is a cost effective, space saving biological treatment alternative in both Municipal and Industrial Waste Water Treatment

The Sequential Batch Reactor (SBR) is a modification of the conventional activated sludge process. In the SBR process all steps of biological treatment and solid/liquid separation are performed in a single reactor during a defined process cycle.

SBR is used generally in secondary waste water treatment when the biological reaction is required to reduce the BOD and COD parameters. In biological waste water treatment design, Dissolved air flotation (DAF) system is normally selected as primary treatment unit in oleo-chemical industry and pulp and paper industry. While DAF system reduces suspended solids and oil and grease to a minimum level, SBR acts as polishing unit to ensure the effluent meeting authority's preset standard.
