Abstract

PURPOSE: To wash filter media for purifying bath water in a bath tank at adequate timing by providing a circulating flow passage with a turbidity detector for detecting the turbidity of the bath water at its proper point. CONSTITUTION: The bath water 3 in a bath tank 2 is lifted up by a circulating pump 4 and the turbidity detector 8 is connected to the downstream of the circulating pump 4 in the circulating flow passage 7 which gushes water from a discharge pipe 6 into the bath tank 2. First and second three-way valves 14, 15 are changed over to pass the bath water lifted by the circulating pump 4 through a flow passage 13 for backwashing, a filter case 9 and a drain path when the preset or higher turbidity is detected by the turbidity detector 8. The bath water is thus passed backward for the prescribed time within the filter case 9 to wash filter media 12. The degree of contamination of the bath water is monitored at all times in such a manner and the bath water is automatically washed.
