Abstract: The well water removal and treatment system of the present invention includes a pumping and well water withdrawl loop consisting of an above ground pump, a pressurized water drive line from the pump outlet to a well water ejector, a water return line from the well water ejector to an aeration and precipitation tank, an inlet line from the aeration and precipitation tank to the pump and a venturi nozzle air mixing manifold fluidically connected between the high pressure drive water line and the lower pressure water delivery line to mix air into the water during the entire pump cycle. The water delivery line from the pumping and withdrawal loop has a flow control regulator therein that controls the water flow therethrough in proportion to the water pressure in the pumping and withdrawal loop above a preselected minimum control level.

Abstract: A system to remove contaminants from water includes, in the pressurized water flow lines, a venturi nozzle assembly to entrain air in the water, a pressure tank to store and deliver the air laden water, an aerator/precipitator tank assembly to remove the excess air and any residual gases from the water in the pressurized system and to remove contaminants from the water and a filter tank having a filtration bed therein to remove the remaining precipitated contaminants from the water and to deliver the water to service.
Abstract: A water filter adapted for installation in the hot and cold water supply lines leading to a faucet, appliance or the like includes a housing containing a granular activated carbon filtration bed and a two position valve with three ports for controlling water flow through the filtration bed. The valve has a first service position for normal flow of cold water through the filtration bed to the effluent line from the water filter and a second backwash position for flow of hot water through the filtration bed in an opposite direction to then drain through the same effluent line.
