Potable water is required to be free of color, odor, disease causing organisms, microbes, organic and inorganic impurities, metal and heavy metal impurities. So depending on the source, water undergoes a series of purification processes till it is fit to be consumed and dispensed for daily needs. Sodium permanganate is an important water treatment chemical which is used at the pre- oxidation stage to eliminate odor caused by sulphides, phenolic and other decaying organic wastes and impurities. Sodium permanganate is also very effective in removing soluble Ferrous, Manganese, Arsenic and other metal impurities by oxidizing it in to insoluble form thus enabling its removal by filteration. The high oxidizing power of Sodium permanganate also contributes in destroying disease causing bacteria, viruses, fungi and other microbes in potable water.
