Recently membrane bioreactors (MBRs) have been applied to municipal wastewater treatment plants. They have many advantages and the reuse of the treated water is expected for various purposes. In this study the applicability for treatment of a kitchen wastewater was examined through a MBR pilot scale experiment. In addition the MBR operational condition for the low water temperature period was also studied. The MBR experiment using the kitchen wastewater was carried out throughout the year. We prepared a newly developed flat sheet membrane made from chlorinated polyvinyl chloride hydrophilized with hydroxy-propyl cellulose, which plays a role to prevent membrane surfaces from the fouling. In the treatment of a kitchen wastewater newly developed membrane maintained the performance for one year only by performing physical cleaning. In addition it confirmed newly developed membrane after one year use kept the hydrophilicity by measuring contact angles and flux. It was observed that our developed membrane was applicable to treatment of a kitchen wastewater including the winter period.
