ABSTRACT
Water available for domestic and industrial applications is not pure and normally contains many impurities. These impurities are generally categorized in ve broad classes: (1) dissolved inorganic compounds (i.e., bicarbonates, carbonates, uorides, sulfate, phosphates of calcium, magnesium, strontium and barium, and small amounts of aluminum, copper, iron, manganese, zinc, and other substances), (2) dissolved gases (i.e., carbon dioxide, hydrogen sulde, oxygen, nitrogen, sulfur dioxide, and
