This study was carried out to verify the applicability of membrane separation bioreactor (MSB) system to municipal wastewater treatment plant in Japan. Five series of pilot plants with two types of flat sheet membrane, two types of hollow fiber membrane, and a ceramic membrane were operated. Each plant consisted of an aerobic tank, an anoxic tank, and membrane units immersed in the aerobic tank. The capacity of the plants was 40 - 70 m^3/day. Raw wastewater was supplied to the plants as the influent. The objective of this study is to investigate ; treatment performance throughout a year and behavior of micropollutant in MSB. The results are summarized as followed ; continuous operation for about two years, temperature ranging from 15 to 33℃ and the concentrations of five kinds of exogenous endocrine disrupting chemicals were measured for the influent, the effluent, and mixed liquor in MSB.
