摘要：Rotating Biological Contactors (RBC) is the only aerobic treatment process that has both moving film of attached-growth biomass and suspended growth microbial systems. The laboratory model of 10.125 liters effective volume has three stages; each having 5 numbers of discs with plastic modular exterior finish on both sides. The treatment performance was studied for treating sugar and dairy effluent streams under varying influent flow rates (m3/day), COD (mg/L) and rotational speed of discs (rpm). It is found that 6 rpm of rotational disc speed is enabled the model to offer the maximum COD removal at 91.66% in the case of sugar effluent and 87.57% for dairy effluent streams.
