Gas Chlorination Systems

Gas chlorination systems are still the most common disinfection technology used in water and wastewater treatment. Although gaseous chlorine has long been considered unsafe, the development of effective safety products, such as automatic shut-off systems, chlorine emergency scrubbers, and vent exhaust gas arrestors, has made chlorine gas systems safer than ever.
