ABSTRACT:
A rotary filtering apparatus basically comprises a tank having inner surfaces comprising an upper part which is cylindrical and a lower part which is conical, wherein a diameter thereof decreases toward the lower part of the tank. A sintered metallic filter is centrally disposed in the tank, and a filter rotating mechanism is provided for rotating the sintered metallic filter in one direction. A fluid supply unit supplies polluted water (W1) to the inside of the tank, and a nozzle unit supplies high-pressure water (H) to the tank. A fluid suction unit draws clean water (W2) out of the central portion of the sintered metallic filter. A storage tank is mounted to the lower part of the tank, for storing therein particles separated from the polluted water (W1).
