APPARATUS AND METHOD FOR TREATING WATER |
摘要 |
<p>There is here disclosed a water treatment apparatus in which a membrane separation device is disposed above a gas diffuser device arranged in a treating tank, wherein diameters of gas discharge holes formed in the gas diffuser device are within a range of 1 to 10 mm, and a relational expression of 20<X/Y<300 is satisfied wherein X is a sectional area (cm<2>) of the membrane separation device in a horizontal direction, and Y is the number of the gas discharge holes of the gas diffuser device. According to this water treatment apparatus, the clogging of the pores in the surface of a separation membrane with a suspended substance can be inhibited, so that a stable filtration is possible for a long period of time. <IMAGE></p> |
