Water sterilization systems with chlorine injection

Chlorination is the most common disinfection method in drinking water treatment projects worldwide. Chlorine kills pathogens and oxidizes iron, manganese, and taste and odor compounds in water. Chlorine may be added to water as a primary disinfectant, as a pre-chlorination, between the sedimentation and filtration process, or as a final treatment step prior to distribution. It can also be added as a secondary disinfectant to the water leaving the treatment project or within the distribution network to prevent re-contamination of the water, and to ensure the safety of drinking water. Despite its effectiveness in improving water quality and killing pathogens, chlorine may lead to the formation of by-products that may be toxic, or may cause problems with the taste and smell of drinking water, so great care should be taken to prevent the formation of these compounds.

Advantages of sterilizing water with chlorine injection

• Cheap
• Effective in purifying water from pathogens and some inorganic compounds (iron, manganese, hydrogen sulfide) non-toxic (in the form of free chlorine)
• Reduces taste and smell problems due to algae and some chemical compounds
