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. The aerator/precipitator tank assembly includes a top manifold sealed on the tank having an inlet operative to spray air laden water into the tank and an outlet selectively operative to vent excess air from the tank while maintaining system pressure, a float valve assembly carried by the manifold selectively operative to open when excess air builds up in the tank to vent the excess air through the manifold outlet and a layer of calcium carbonate rocks in the bottom of said tank to continue removing iron contaminants from the water moving downwardly therethrough.
