<p>21 A system for treating water includes an aerator or degasifier that is fluidly connected to a blower that moves gases released from the water cascading down in the aerator over slat trays or plastic packing media. The release gases enter a gas scrubber and are treated with an iron salt solution that removes undesirable gases and that form a sludge that is removed from the scrubber. The residual gases, mostly nitrogen, argon, and other minor gases found in ambient air, flow into the aerator. In some instances, the gas scrubber also includes, in addition to the iron salt solution treating equipment, equipment for treating the released gases with caustic soda solution.</p> |
