Abstract

PURPOSE:To drastically diminish the replacement frequency of a filter and to enable use in a long period by providing both a microorganism filter tank wherein a film is formed of microorganisms and a sterilizing tank in which a photocatalyst receiving light of a lamp has sterilizing force in the flow direction of water in this order. CONSTITUTION:When a pump 16 is started, hot water in a bathtub 15 flows in the direction shown by an arrow through a flow path 2. Microorganisms stuck on a human body and microorganisms in the air are mixed into hot water and stuck to a filter medium 5 in a microorganism filter tank 3. These microorganisms absorb organic substance such as scale and various bacteria. While decomposing it into CO2 and water, the microorganisms perform self- multiplication and the surface of the filter medium 5 is covered with the shape of a film. The organic substance such as scale is adsorbed by the filter medium 5 of the microorganism filter tank 3. Thereafter, hot water is advanced through the flow path 2 and introduced into the next sterilizing tank 10. Thereby, since a photocatalyst receives irradiation of a lamp 13 and has large sterilizing force and is present in the sterilizing tank 10, various bacteria in hot water is killed and decomposed in the tank 10.
