Treatment of Wastewater Using an Integrated Submerged Attached Growth System

Abstract:

The performance of a single sludge integrated attached growth system comprising of an aerobic and anoxic tanks in biological nutrient removal was evaluated in treating synthetic wastewater simulating medium strength domestic wastewater. An aero-packer and bio-balls were installed in the aeration and anoxic tank occupying about 40% and 25% of both tanks respectively. The efficiency of the integrated attached growth system was evaluated on the removal of chemical oxygen demand (COD), ammonia removal (NH₃), nitrate removal (NO³), total suspended solids removal (TSS) and biochemical oxygen demand removal (BOD₅). Effluent results show that the integrated attached growth system had a removal efficiency of 97.8% (COD), 97.5% (NH₃), 87.5% (NO3), 97% (TSS) and 97.1% (BOD). These results support the viability of an integrated system in mitigating the enormous challenges of a conventional wastewater treatment.
