Performance Analysis of Wastewater Treatment System - A Review

The work aims to study performance of a various combination of technique for effective domestic wastewater treatment. Effort was made to developed treatment option to treat the domestic waste by using attached growth system and combined attached & suspended growth system. For attached growth system constructed wetland, modified multimedia filtration process are used & for CSAG system RDR technology is used , RDR adopts rotation pattern to enhance the efficiency of domestic wastewater treatment. To study the performance of the reactor, laboratory models were fabricated with GI sheet having appropriate dimension. The model were provided with appropriate arrangements of inlet, outlet. The lab scale model was operated for different operating conditions at different detention time. The studies were carried out to analyze the performance of reactor for removal of various parameters such as BOD, COD and TS. It is found out that constructed wetland gives best % BOD removal of 81 %, % COD removal of 77% and % TS removal of 86
