PURPOSE: Filtration, sterilization/disinfection, and heat recovery apparatus is provided to reduce water and energy consumption and to maintain the cleanness of a warm water bath and a cool water bath through filtration, sterilization/disinfection, and heat recovery processes. CONSTITUTION: The evaporating conduit of coolant is arranged at the center part of a cool water bath side filtration unit(420). The condensing conduit of coolant is arranged at the outer circumference of a first filter in a warm water bath side filtration unit(410). The warm water bath side filtration unit emits condensing heat from the condensing conduit of the coolant in order to heat circulating water. The cool water bath side filtration unit absorbs evaporating heat from the evaporating conduit of the coolant and cools the circulating water. The warm water bath filtering unit includes a first filter(411) and a second filter. An electric heater(412) is installed between the first filter and the second filter. If the filters are used for a long period of time, the circulating water is stopped. The temperature of electric heater is raised to a sterilization/disinfection temperature. |
