Biological Treatment of Milk Factory Wastewater by Sequencing Batch Reactor

Aerobic Sequencing Batch Reactor (SBR) experiments in the bench scale was investigated to study the treatability of wastewater from milk factory. The reactor was fed with milk factory and synthetic wastewater under different operation conditions. The COD removal efficiency was achieved more than 90%. The optimum oxygen in the reactor was found to be 2 to 3 mg/l. The study demonstrates that the capability of aeration SBR for removed of COD from industrial wastewater.
