ABSTRACT:
This invention presents a system and a method for the removal of unwanted contaminates such as hydrogen sulfate, nitrites, manganese and iron from potable water by the process of oxidization. The invention employs a common water softening system utilizing a specialized piston within the piston valve assembly to direct the flow of water throughout the system during normal use and during an air regeneration cycle and check on the water intake line and air intake line to prevent the escape of pressurized air trapped within the tank.
