Boiler Feedwater Treatment (Part I): Why Water Treatment

Chemical composition of water. Pure water, H2O, is a simple combination of hydrogen and oxygen. There are, however, several hybrids forms of water in all supplies. Water often contains about 300 ppm of deuterium oxide, D2O, or 'heavy water'. It has no use as drinking water or in making plants grow, but in pure form has found use in nuclear
