<p>PROBLEM TO BE SOLVED: To provide a membrane separation type cleaning tank capable of easily performing the maintenance/inspection work of a membrane separator. SOLUTION: In a membrane separation type cleaning tank having a membrane separation tank E2 housing a membrane separator and the upstream tank E1 adjacent to the membrane separation tank E2 through a diaphragm and constituted so that the water to be treated in the upstream tank E1 is transferred to the membrane separation tank E even in such a state that the water level of the upstream tank E1 is lowered to the position lower than the upper end position of the membrane separator, the opening part 34 opened at the position lower than the upper end position of the membrane separator of the diaphragm W is formed and an on - off mechanism 3 capable of closing the opening part 34 in a liquidtight manner is provided.</p> |
