MEDIUM AND MEMBRANE FILTRATION-COMBINED FILTRATION FACILITY, AND OPERATION METHOD THEREFOR

摘要

<P>PROBLEM TO BE SOLVED: To provide a filtration facility and an operation method therefor with little risk and with extremely excellent water treatment efficiency, the facility achieved by combining filtration technologies of a conventional media filter basin and a membrane filtration apparatus to solve problems of both the technologies and made compact by reducing a installation space, and exactly and flexibly coping with the increase or fluctuation of water to be treated and variation of water quality. Ž<P>SOLUTION: The medium and membrane filtration-combined filtration facility includes a media filter basin M and a membrane filtration apparatus S formed by disposing a plurality of membrane modules 16 in a filtration tank 11 of the media filter basin at a position lower than the water level L of the water to be treated at the filtration time. The water H to be treated fed to the filtration tank 11 is simultaneously filtered in both the media filter basin and membrane filtration apparatus, to simultaneously obtain treated water from both the media filter basin and membrane filtration apparatus.
