PURPOSE:To obtain mineral-contg. active water by providing vertically and freely attachably and detachably a primary filter cylinder in which a filter medium is packed, an active cylinder in which water quality improving stone such as 'BAKUHANSEKI' (siliceous stone) is packed and secondary filter cylinder in which the filter medium is packed into a tank and providing a conductive sensing part. CONSTITUTION:Water to be treated passes through a supply pipe 1 and rises in the primary filter cylinder 2 from the bottom of said cylinder 2. Harmful org. materials such as turbidity and odor and heavy metals in the inflow water are adsorbed to the filter medium during this time. The filtered water is then admitted through release holes 2a in the upper part into the tank 3 in which a liquid level control means 4 is vertically provided to the bottom. A solenoid valve turns off and the water feed is stopped at the point of the time when the water level arrives at the position W and all the upper, middle and lower leads are conducted. The water stored in the tank 3 is circulated through the tank 3 the active cylinder 8 the release holes 8a of the active cylinder the tank 3 during the time set by a timer 7. The water is cleaned up by contacting with the 'BAKUHANSEKI' in the cylinder 8 during this time. |
