Method for purifying a fluid

摘要

A photocatalytic oxidation purification system includes an ultra violet light source and a filter that comprises a pleated wire mesh substrate with a nanophase metal oxide oxidation catalyst suspended on the substrate, wherein the catalyst is applied without an adhesive using an electromechanical plating process. As a fluid containing organic contaminants is directed through the filter in the presence of ultra violet light from the light source, the catalyst oxidizes and decomposes the organic contaminants into environmentally harmless components. Methods of making the purification system including preparing a solution of catalyst and applying the catalyst without adhesive binding material to the filter substrate electromagnetically.
