Chlorine /Free Chlorine

...

Chlorine is the most widely used oxidizing biocide today for disinfection of domestic water supplies as also for the removal of tastes and odours from water. The amount of chlorine required to be added in a water system is determined by chlorine demand, contact time, pH and temperature of the water. A Chlorine residual in drinking water indicates that:
1) Disinfection has been achieved by chlorine and bacteria and viruses that cause diarrheal disease have been eliminated; and,
2) the water is protected from recontamination during storage. Free residual chlorine in drinking water is a measure of potability of water.
