Sulfate in water (SO4) naturally in our environment. Generally, sulfate in water originate from the oxidation of sulfite ores, the presence of shales, and the existence of industrial wastes. Sulfate is one of the major dissolved constituents in rain water. High concentrations of sulfate in drinking water causes a laxative effect when combined with calcium and magnesium, the two most common components of water hardness. Bacteria which attack and reduce sulfates, causes hydrogen sulfide gas (H2S) to form. The EPA has suggested sulfate water levels of 250 mg/l published in the Secondary Drinking Water Standards. Furthermore, the EPA has calculated that about 3% of the public drinking water systems may have sulfate water levels of 250 mg/L or greater in there water supply.
Sulfate Water Treatment - There are several sulfate water treatment options available. Reverse Osmosis Systems will reduce the sulfate content in water by 97 - 98%. Sulfates in drinking water can also be reduced with a strong base anion exchanger, which is normally the last half of a two-column deionizer. If you have any questions about the effects of sulfate in water, and or sulfate water filtration and treatment options please give us a call.
