Abstract
PURPOSE: To clean the semipermeable membrane in a module safely and easily by moving elements for membrane cleaning back and forth through the simple operation of a 4-way valve.
CONSTITUTION: When a 4-way change-over valve 1 is communicated with the forward direction shown by an arrow (a) in the flow direction of raw liquid from a raw liquid supply pipe 21, sliding elements 5 are put into the chamber 4b of a concd. liquid outflow pipe 23. If the valve 1 is so communicated that the flow of the raw liquid goes backward (b), the elements 5 in the chamber 4b are moved into a chamber 4a through the tubular semipermeable membrane in a module M, and at the time when the elements 5 pass through the inside of the tubular semipermeable membrane, the scale on the inside surface of the membrane is rubbed off. The elements 5 are moved back and forth within the module M by operating the valve 1 to the forward communication and backeard communication by way of an intermediate state that helps prevent the elevation of pressure, whereby the scale on the inside surface of the semipermeable membrane is removed perfectly.
