生物ろ過槽３内の濾材５に付着する。The operation of the circulation filtration device having the above construction will be described below. In FIG. 1, when the pump 16 is started, the hot water in the bathtub 15 flows in the flow path 2 in the arrow direction. After the microorganisms attached to the human body and the microorganisms in the air are mixed in the hot water, they are attached to the filter medium 5 in the microorganism filtration tank 3.
【００１５】この微生物は湯垢雑菌等の有機物を吸収

Also, if the microbial film is thickened more than a certain amount, the deep part may die due to lack of enzymes and nutrients, and hydrogen sulfide and ammonia may be generated.
The water supply valve 6b and the drain valve 6d are sometimes opened and the flow path valves 17, 17 are closed to backwash the filter medium 5.
【００１７】上記微生物ろ過槽３の濾材５で湯垢等の有
