Title:
WATER PURIFIER
Document Type and Number:
WIPO Patent Application WO/2005/113449
Kind Code:
A1
Abstract:
A small and easy-to-handle water purifier capable of accelerating production of a flock of impurities and removing impurities in waste water in one pass. An inner tubular cathode (12) made of stainless steel or carbon is disposed through a gap (13) of a specified size on the inner side of an outer tubular anode (11) made of aluminium, and aluminium hydroxide is produced by electrolysis. Using the aluminium hydroxide thus produced as a medium, impurities in waste water ascending through the gap (13) are aggregated. When the waste water containing aggregated impurities is filtered through a filter (18) arranged in a sedimentation/filtration tank (17), impurities in the waste water are removed thoroughly.
