<p>PURPOSE:To attain the purification of hot water for a bathtub from the beginning of utilization by disposing microorganism filtering device providing a carrier of a ceramic granules sticking forcedly microorganism to the surface in advance to a circulating path. CONSTITUTION:Hot water for the bathtub is introduced into the purifying device main body through a suction pipe 5 in a state hairs are removed by a hair catcher 8. Hot water for the bathtub is filtered by the physical filtration device 10 and also in the bio-filtration device 11, further smaller organic matters are removed and sterilized by an ultraviolet sterilization device 12 and become a completely purified state. At this time, since a part of the ceramic granules 15 in the filtration tank are previously stuck with the microorganism in advance, the beginning of utilization of the purifying device, hot water for the bathtub is purified by the action of this microorganism and thereafter the microorganism suitable to the state of hot water for the bathtub is proliferated gradually. Accordingly, the purification of hot water for the bathtub is attained from the beginning of utilization and the unsufficient purification condition until the microorganism is stuck on the surface of the ceramic particles 15 is avoided.</p> |
