Abstract

PURPOSE: To prolong the life of a hollow yarn membrane by incorporating a scrubbing stage in succession to backwashing by compressed air, and effectively removing the suspended matter deposited on the hollow yarn membrane and which is difficult to release.
CONSTITUTION: When the hollow yarn membrane filter for filtering radio-active waste liq. or condensate is backwashed, a dome drain valve 3 and a compressed air valve 2 are opened to discharge the liq. in the dome. Then only the valve 3 is closed, a backwashing discharge valve 9 is opened, and the liq. is discharged at a stretch to the height of a tube plate 11. The valve 9 is then closed, water is supplied and filled to a height under the tube plate by opening the valve 3, a tube plate vent valve 5, and a water inlet valve 7, the valve 5 is closed to fill the water to a dome drain port, the valves 3 and 7 are closed and an air scrubbing valve 8 and the valves 5 and 2 are opened to carry out air scrubbing, the valve 2 is closed, and air scrubbing is continued. The valve 5 is closed and the valve 9 is opened to discharge the liq. contg. suspended matter, and the valve 8 is closed and the valve 3 is opened to resume the filtration.
