Review Paper on Treatment of Food Industry Wastewater by Sequencing Batch Reactor
Abstract: Food industries have an important place in the Indian economic development. However, the wastewater generated from these industries bear a high degree of pollution load. A membrane separation process was coupled to a sequencing batch reactor (SBR) for biological nutrient removal (BNR) processes and a combined system was named a membrane sequencing batch reactor (MSBR). MSBR was used for the treatment of dairy industry wastewater and optimized to increase the treatment efficiency. Since a diffuser-attached module design, subcritical flux operation, and intermittent suction method were adapted to the system, long-term operation was possible, i. e. the system could be operated for more than 110 days with only one membrane washing. BOD removal was high (9798 %) and stable. SS (suspended solid) -free effluent was obtained by membrane separation. Since nitrogen was mainly consumed as nutrient for synthesis of new cells due to the low influent concentration, the removal rate reached 96 %. Phosphorus removal was relatively low because of the limit of the biological process, i. e. removal efficiency ultimately depends on the amount of excess sludge wasting. A removal rate of 80 % was reached after system optimization.
