Recently, the introduction of separation membranes is progressing in the field of sewage and industrial wastewater treatment. The treatment methods with membrane separation have many advantages. Firstly, the sedimentation tank has not been required for the sake of gravity sedimentation. It is possible that the reaction tank become compact. Secondly, suspended solids (SS) can be almost completely removed, and it is possible to produce clarified treated water for which even bacteria and viruses can be almost completely removed. For this research, a new and novel separation polytetrafluoroethylene (PTFE) membrane has been produced, and the membrane has been applied to membrane bioreactor and membrane separation coagulation sedimentation treatments on an actual sludge treatment center. The experiment data was obtained through continuous operation during over approximately one year, and did show the similar good performance to a chlorinated polyethylene (CPE) membrane. As a result, the fouling resistance was considerably improved when using the flat PTFE membrane compared to the flat CPE membrane.
