Abstract

PURPOSE: To decrease the amount of production of secondary waste by providing a concentration filtration means within the system of a pool liquid filter device and passing the pool liquid emerging from said means through a cartridge filter when the clod concn. in said liquid increases more than a predetermined concn.
CONSTITUTION: The pool water in a skimmer surge tank 2 is circulated continuously by a pump 3 within a concentration filtration device consisting of the circulation system of the pump 3, concentration filtration device (tubular porous filter body) 7, valve 8, and skimmer surge tank 2. The pool water (permeated water) having been purified by passing the device 7 is stored in a purified water tank 9 and is returned into a solid waste storage pool 1. On the other hand, the clod concn. in the system is measured with a turbidity switch 13, and when it reaches a predetermined concn., a valve 14 is opened to flow the liquid to a cartridge filter 5, whereby the clod is captured with the filter 5. When the concn. lowers down to the predetermined concn. or lower, the valve 14 is closed and the concentration process is started again.
