Water chlorination is the process of adding chlorine or hypochlorite to water. This method is used to kill certain bacteria and other microbes in tap water as chlorine is highly toxic. Many small public water systems use chlorine to protect against bacteriological contamination. Typical treatment systems use diaphragm or peristaltic pumps to inject sodium hypochlorite solution into the water supply. These systems must provide consistent, minimum free chlorine residual whenever the water system is operating to inactivate pathogenic organisms such as viruses and bacteria effectively. If the water flow rate is relatively constant, adding chlorine at a fixed injection rate may be adequate. If the water flow fluctuates significantly, adding chlorine at a variable injection rate is more appropriate. In either case, operators adjust the chlorine residual by changing the injection rate of the chlorine feed pump, and by changing the strength of the chlorine solution.
