The high performance submerged membrane module using flat sheet membrane was introduced and employed in the waste water treatment by MBR. The flat sheet membrane has the characteristics of ultrafiltration with the pore size of 0.04 µ m and thin thickness of 2 mm so as to obtain the high quality of treated water and to save the space of the module installation. In order to reduce the energy consumption of MBR, we introduced the effective membrane cleaning process, the so–called mechanical cleaning process, MCP. The effectiveness of MCP is examined and verified by using the pilot–scale testing equipment. We estimated that the energy consumption per treated water of MBR can achieve the value of less than 0.4 kWh/m3 by using MCP with the high performance submerged flat sheet membrane module.
