Performance Evaluation of Semnan Industry Park's Advanced Wastewater Treatment Plant system (MBR) in Industrial Effluent recovery

In the present study, the performance of Semnan Industry Park’s MBR/RO advanced treatment system for industrial effluent reusing was investigated.
To determine the performance efficiency of full-scale membrane bioreactor (MBR) with submerged polyether sulfone flat sheet modules (MA04-150, pore size of 0.05 &mum) into an aeration tank, the potential removal of nitrogen, phosphorous, BOD ,COD and TSS for industrial effluent reuse were investigated by seasonal sampling from MBR influent and effluent.
The results showed that the obtained removal efficiency of system for BOD, COD and TSS were more than 98 %, which increased in Summer. Furthermore, MBR reactor efficiency for the removal of nitrate, ammonia and TKN were 35%, more than 90% and 79% percent, respectively. The MBR removal efficiency for phosphorus was determined by an average of 52% . Low efficiency is due to low levels of phosphorous in the reactor.
According to the results and to compare it with existing standards , it can be stated that the Semnan Industrial Park advanced treatment system meets its founding objectives and namely can be used agricultural and industrial operation.
