tablets/filters. It is more efficient than the formerly used
halazone water disinfectant. In these applications, it is a slow-release source of chlorine in low concentrations at a relatively constant rate. As a disinfectant, it is used to sterilize drinking water, swimming pools, tableware and air, and to fight against infectious diseases as a routine disinfection agent.
It can be used for disinfection and environmental
sterilization, for example in livestock, poultry, fish and
silkworm raising, for
bleaching textiles, for cleaning industrial circulating water, and to prevent wool from shrinking.
