Title: Water treatment apparatus
Inventor: SAWADA SHIGEKI
IPC: C02F1/70
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To prevent the contamination of a filter membrane by installing an ozone-oxidation apparatus for ozone-oxidizing raw water in the pre-stage of a membrane filter. SOLUTION: An ozone contact column which injects ozone into raw water to oxidize it is installed in the pre-stage of a precision filter membrane for membrane filtration. A reverse osmosis membrane is provided in the post-stage of the filter membrane to constitute a water treatment apparatus. When ozone oxidation treatment is implemented in the pre-stage of a membrane filter which is used for the pre-treatment of a reverse osmosis apparatus, polymeric humic acid and fulvonic acid which are TOC components in the raw water are reduced, and organic components are also decomposed into low molecular weight components. In this way, these acids are adsorbed/adhered on/to the membrane surface of the membrane filter so that the increase of membrane filtration resistance is prevented and the organic substance contamination of the membrane filter can be controlled.
