Gas chlorination is a process used primarily for water disinfection. Most people are familiar with the use of chlorine in swimming pools to eliminate bacteria and algae buildup. While this is a well-known application for gas chlorination, there are numerous industrial and water treatment purposes that benefit from chlorine water cleansing as well.

For industrial and commercial purposes, gas chlorination systems are used to effectively monitor and disperse chlorine into water systems on a continuous basis. Through sensitive machinery, chlorine gas is added to the water to maintain a specified residual at all times.
