Abstract
PURPOSE: To perform washing efficiently with a small amount of a washing liquid by dividing many membrane module pressure-tight pipes into a plurality of blocks and by supplying the washing liquid to each block successively while permitting the liquid after washing to recirculate to said pressure-tight pipes.
CONSTITUTION: Among membrane module block groups 4, 5 and 6, group 4 has permeating liquid discharge valve 20 closed firstly and charge change-over valve 9 and discharge valve 12 opened to feed a washing liquid through pump 7. Further, compressed air is supplied to pressure-tight pipes via air injection valve 16 for air- bubble washing and bubbles are exhausted via open valve 23. The washing liquid having washed membrane module pressure-tight pipes returns to washing-liquid tank 8 for circulatory use. The perferable washing time of membrane module block groups is about 10min. After the washing, valves are changed over and module block groups 5 and 6 are washed successively as well.
