Abstract

PURPOSE: To effectively sterilize and maintain the operation-stopped module free from drying by a method wherein the membrane type separation module is filled with sterillizer solution supplied from high-position tank with pressure of sufficiently high head.
CONSTITUTION: A sterilizer tank 12 is installed above a membrane type separation module 1, and both are connected with pipes 13, 15, 6, valves 16, 14, 17, and pump 5. When the module 1 is out of operation, the valves 4, 14, 9 are closed, and the liquid supply pump 5 is run, so that sterilizer liquid is supplied from the tank 12 to the module 1, and solution within the module 1 is discharged from the drain pipe 18 and replaced with the sterilizer liquid. Then, the valves 16, 17, 8 are closed, the valve 14 is opened, so that the sterilizer liquid in the module 1 is pressurized with the head of the tank 12. This causes the sterilizer liquid to exude on the surface of the module 1 so as to prevent microbes from growing. By supplying water to the tank 12 in amount corresponding to the water transmitted from the module 1, sterilizer liquid concentration in the module is maintained at a substantially constant value.
