Abstract

PURPOSE: To prevent breaking of membranes by a method wherein a gas-liquid separation pipe having an air release valve to discharge cleaning air is installed downstream a membeane module, and air inlet and release valves are associatedly opened and closed so that no back-pressure is applied to the membrane.
CONSTITUTION: To clean the membrace support pipe in the membrane module 1, the cleaning liquid inlet valve 7 is first opened so that a cleaning liquid is injected into the module 1 via pipe 5. At this stage, the cleaning air inlet valve 6 and the air release valve 10 are closed. To perform the following bubble cleaning, a control signal fromthe control panel 12 opens the inlet valve 6 installed on the pipe 4 through which cleaning air is forced to pass at a specified pressure, and at the same time, the air release valve 10 is opened. The air passed through the pipe 5 is distributed in the membrane module 1 and performs bubble cleaning, then goes to the gas-liquid separation pipe 9 where the air and cleaning liquid are separated and the separated air is discharged from the release valve 10.
