| Outline of Final Research Achievements |
A pilot plant study of the buffled MBR with PTFE membranes of 3 m long ,which can achieve simultaneous removal of BOD, T-N and T-P in a single reacto, was carried out. As the results, stabler removal of BOD, T-N and T-P was observed, and the electric power consumption rate of 0.35 kWh/m3 was obtained. It is very low compared with the existing MBR.We developted a nove PTFE hollow fiber MF membrane module with intensive air diffuser. A series of small pilot plant experiment showed a quite low electric power consumption is possible in the MBR with the novel module. P recovery from the MBR exess sludge was possible when the effluent from the MBR was treated through the column filled with zirconia mezo-structured paricles. Anaerobic MBR with a MF hollowfiber membrane incoorated with zirukonium mes- structured particles has a high potential for the phosphate recovery from the excess sludge.
