Industrial effluents and Sewage wastewater are generated in colossal proportions near industrial towns and densely populated cities. If left untreated, it contaminates the groundwater source, lakes, rivers and aquifers with high heavy metal content, organic and inorganic impurities. So it is imperative that all effluents be treated and neutralized at effluent treatment plants before it is disposed of. Sodium permanganate plays a major role in the treatment of effluents by oxidizing soluble metal and heavy metal impurities into insoluble forms. Sodium permanganate also oxidizes odor causing sulphides and mercaptans from Industrial wastes to simple elements. Sodium permanganate neutralizes organic hydrocarbons and phenolic compounds to carbon dioxide and water, thus rendering effluent safe for disposal.
