JPH10230280A - Sanitary control method of circulation type bath water - Google Patents

Abstract

PROBLEM TO BE SOLVED: To perform effective purification and sterilization by allowing a chemical containing a chlorinated isocyanuric acid based compound or halogenated hydantoin based compound as an effective component to contact with a circulation type bath watt. SOLUTION: The sanitary control of the circulation type bath water is performed by allowing the solid chemical containing the chlorinated isocyanuric acid based compound or the halogenated hydantoin compound as the effective component to contact with the circulation type bath water. Any method by continuously or intermittently charging can be used for the contact of the chemical with the circulation type bath water and if necessary, the chemical is automatically charged with a timer set. The bath water is treated at the bath temp. for several seconds to several hours. Where, to prevent the rapid increase of the concentration of activated chlorine, a chemical cylinder holding the solid chemical can be arranged in the circulation line of the bath water to dissolve and supply the chemical by a prescribed quantity for a fixed time.

Description of the Related Art A circulating bath is a bath in which a bath is kept at about 40 ° C. while removing various germs in a purification device so that the bath can be taken at any time. Conventionally known circulating bath water purification methods include a microorganism purification method, an ozone purification method, an ultraviolet purification method, and the like.However, these purification methods do not provide a sufficient purification / sterilization effect, and general bacteria grow. Hygiene problems have arisen, in particular, the presence of Legionella spp. Has been detected at a high rate, and there is an urgent need to take preventive measures against Legionella infections such as fulminant pneumonia and systemic infections. In addition, JP-B-62-380
No. 3 discloses a rapidly dissolving tablet having a bactericidal performance using an alkali metal salt of dichloroisocyanuric acid as an active ingredient, but does not describe a case relating to infectious diseases such as Legionella.
