ABSTRACT:
A water treatment apparatus provides treatment of water to remove, for example, hydrogen sulfide and iron, dissolved or dispersed in ground water. The system is provided with water from a conventional well and pump and includes a venturi-type aerating device which may be supplied air by a compressor. The air and water mixture are supplied to a first aerating tank through a spray nozzle which reduces the aerated water flow to a mist of fine droplets. A draw tube adjacent the bottom of the first tank provides the water to a treatment tank which is partially filled with a chemically active filtration media. The treatment tank is also equipped with a draw tube which draws off the treated water at the bottom of the tank and provides it to a third, deaerating tank wherein the air separates from the water and is purged to the atmosphere. Reduction of hydrogen sulfide content from 30 ppm to less than 5 ppm has been achieved.
