PURPOSE:To remove the harmful materials, malodor generating materials, polluting materials, etc., contained in the hot spring water in a bath tub and to improve the quality of the hot spring water by interposing a microorganism septic tank for propagating microorganisms, metal ion generating bodies and nonmetal ion generating bodies in a route for circulating the hot spring water. CONSTITUTION:The circulation route of the hot spring water purifying system for purifying and reusing the hot spring water 2 in the bath tub 1 while circulating the hot spring water is provided with the microorganism septic tank 9 for propagating the microorganisms (e.g. aerobic and anaerobic microorganisms) and >=1 kinds of the metal ion generating bodies 6 and >=1 kinds of the nonmetal ion generating bodies 7 are interposed in the downstream side of the microorganism septic tank 9. Consequently, the hot spring water is purified to get rid of the harmful materials and malodor generating materials contained therein; in addition, the hot water is subjected to an ion exchange and ion adsorption by utilizing an ionization phenomenon, by which the polluting materials and malodors are removed and the quality of the hot water is improved. |
