Abstract:
A device for treating polluted and recycling water to oxygenize the water and to separate polluting particles contained therein, said device comprising a tank for holding said water with air overhead, and having located therein vertically oriented conically tapered open-ended elongate cyclone chamber having an open top end located in the air above the level of the water being treated, and having an open bottom end submerged below the surface of the water being treated, said cyclone tapering from a narrow top end to a wider bottom end, said cyclone having an inlet arranged tangentially adjacent the lower end of the cyclone wherein water to be treated is tangentially introduced into the cyclone whereupon to cause water introduced into the cyclone to rotationally move in a spiral upwards along the inside wall surface of the cyclone, said cyclone including an outlet in the bottom end thereof, whereupon a portion of the water introduced in the cyclone exits the cyclone from the upper end thereof, carrying separated polluting particles, while the majority of the water introduced into the cyclone exits the cyclone from the bottom end with air being entrapped therein, said tank having (a) an outlet adjacent an upper end thereof, wherein particles carried upwards in the cyclone and exiting from the upper end thereof may be removed by skimming, (b) an outlet adjacent the lower end of the tank, wherein treated water may be withdrawn and recycled, and (c) an inlet for maintaining the level of water in the tank.
