  • Cleaning By Liquid Or Steam (AREA)
  • Separation Using Semi-Permeable Membranes (AREA)

Abstract

PURPOSE: To effect sufficient cleaning of very dirty membrane through increased cleaning cycle using balls by a method wherein plural trap/project devices for membrane-cleaning balls are installed in circulation route of a membrane separation unit, and these devices are synchronized with in-route valve operation.
CONSTITUTION: Balls are used to clean membrane, pass through route 14, reach the first trapper 100A, and are stopped if the valve 23 is open. If the valve 23 is closed, the balls pass through route 25, 26, enter the second trapper 100B, and are stopped when the recoverer 17 contains balls, then, after the recoverer 17 has discharged the previous balls, enter the recoverer 17. The balls in the recoverer are discharged, at valves 23, 19, 20 open, valves 21, 22, 18 closed, into cleaning route together with raw water. Even if module route is long so that ball circulation time is long, this device allows continuous ball flow for cleaning by switching valves.
