Description

A 12% solution is widely used in waterworks for the chlorination of water and a 15% solution is more commonly used for disinfection of waste water in treatment plants. High-test hypochlorite (HTH) is sold for chlorination of swimming pools and contains approximately 30% calcium hypochlorite. The crystalline salt is also sold for the same use; this salt usually contains less than 50% of calcium hypochlorite. However, the level of active chlorine may be much higher.

Chlorine Stabilization

Chlorine gas in water form HOCL which reacts with stabilizer and form N-Chloro-Sulphamic Acid to N-ChloroSufamic Acid more stable and yet has active chlorine,
