Sodium Hypochlorite is made up of the sodium chloride and is a chlorine containing compound that can be used as a disinfectant. It is produced when chlorine gas is dissolved in sodium hydroxide solution. It is reasonably stable due to its high alkalinity.
This process is based on electrolysis of seawater as it flows through an unseparated electrolytic cell. The resulting solution exiting the cell is a mixture of seawater, sodium hypochlorite, hydrogen gas and hypochlorous acid.
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 which makes it possible to eliminate the constraints imposed by considerations of safety when large amounts of liquid chlorine have to be stored. There is no need to provide large reagent storage tanks since production of sodium hypochlorite proceeds continuously to meet the demand as it occurs.
