CONSTITUTION:An air-siphon chamber 17 is formed below a membrane 15, and an air feed pipe 35 is connected to the chamber 17. When compressed air is sent into a first chamber 23 under pressure through the pipe 35, air is accumulated at the upper part in the first chamber 23 and second chamber 25, the liq. surface in both chambers 23 and 25 is lowered as the accumulated air increases, the liq. surface in the second chamber 25 is lowered below the lower end of an upper partition wall 39, and hence the accumulated air flows into a third chamber 28 and is blown off from an air blowoff port 27 in an instant. The air is intermittently blown off, and the formed air bubbles are lumped and ascends in a passage between the membrane elements 12. Accordingly, the membrane surface is efficiently cleaned even with a small amt. of air, and a cake layer on the membrane surface is strongly released.
