摘要 |
Water clarifying apparatus has a cylindrical tank where particulate contaminants suspended in raw water are separated using flotation techniques. A set of concentric mutually spaced, conical plates are positioned in the flotation tank. The plates rotate about the tank, preferably in unison with a (i) header that distributes equal quantities of raw water to each annular zone in the tank defined by the conical plates and (ii) a scoop for removing the contaminants which form a floated sludge layer. A screw conveyor is located in a discharge pipe of the floated sludge scoop. A infrared sludge detection array in a window in the side wall of the tank senses the sludge-water interface. Air dissolving tubes operating in parallel have common feeds and discharges coupled through three way valves operated to pressurize a closed volume of water with high pressure air in one tube while reloading and discharging the other tube. |
