This involves manufacturing sodium hypochlorite and electro chlorination on the spot by the electrolysis of sodium chloride solution. The application of this method is particularly attractive when the salt solution is available in the form of sea-water chlorination makes it possible to eliminate the constraints imposed by considerations of safety when large amounts of liquid chlorine have to be stores. There is no need to provide large reagent storage tanks since the manufacture of sodium hypochlorite proceeds continuously to meet the demand as it occurs. Where the starting solution is an artificially prepared sodium chloride solution, the problems of handling and transport are greatly simplified by the fact that the reagent is harmless.

It is highly effective oxidizing agent with powerful deodorizing and bleaching properties. Its action on pathogenic substances is at least equal to that of chlorine. Capital Controls India as Chlorination Manufacturers Middle East is a leading provider of comprehensive water treatments products. It should be used in reference to chlorine whenever the water to be treated contains traces of phenol which are able to combine with the chlorine giving the water the unpleasant taste of chlorophenol. It quickly oxidizes iron salts, which it converts into insoluble ferric hydroxide. Similarly, when used in excess of a concentration which varies with the pH of the water, it precipitates manganese salts in the form of manganese dioxide. Used at the pre chlorination stage, it therefore enables these metals to be eliminated. Chlorine dioxide is invariably produced oh the spot by reacting chlorine or hydrochloric acid in solution with sodium chlorite.
