Abstract

Background and aims: In the present study, the performance of membrane bioreactor (MBR) advanced treatment system of Semnan Industry Park was evaluated for industrial effluent reusing. Methods: To determine the performance efficiency of full-scale MBR with submerged polyether sulfone flat sheet modules (MA04-150, pore size of 0.05 μm) 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. Results: 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. Conclusion: According to the results and to compare it with existing standards, it can be stated that the advanced wastewater treatment system of Semnan Industrial Park meets its founding objectives and can be used in agricultural and industrial operation.
