advantages of chlorine dioxide over chlorine

Besides these practical advantages there are also considerable economic advantages for the usage of chlorine gas disinfection Chlorination of water supplies can be achieved using three different chemical mediums chlorine gas calcium hypochlorite (available as a solid in granular form) or sodium hypochlorite (the equivalent to liquid bleach)
