DEACTIVATING METHOD OF PATHOGENIC MICROORGANISM

摘要

PROBLEM TO BE SOLVED: To provide a deactivating method of pathogenic microorganism by which waste of power consumption and shortening of lamp lifetime can be prevented as much as possible even when applied to a liquid to be processed largely varying in UV ray transmitivity. SOLUTION: In the deactivating method of pathogenic microorganism in a liquid to be processed by UV ray irradiation, a pulse UV ray is used as the UV ray. COPYRIGHT: (C)2004,JPO
