Document Type and Number:

WIPO Patent Application WO/2007/043592

Kind Code:

A1

Abstract:

[PROBLEMS] To provide an apparatus for production of water through a photocatalytic reaction, which can produce water containing a satisfactory amount of an active oxygen species, can eliminate microorganisms, parasites or protozoa, shows a high oxidizing ability for a prolonged period of time, can reduce the power requirements, is small in size, and is applicable to various devices. [MEANS FOR SOLVING PROBLEMS] A photocatalyst is irradiated with light emitted from a light source to produce an active oxygen species, and the active oxygen species is diffused in water, whereby the water is provided with the functions of the active oxygen species. An oxidation reaction with the water is utilized to perform at least one selected from the elimination of microorganisms, the elimination of parasites and the elimination of protozoa.
