The removal of chlorine from water supplies is a process that aims to eliminate or neutralize the chemical element added as a disinfectant. This procedure improves the taste and odor of water, making it more palatable for consumption and other uses. Methods employed to achieve this range from simple techniques applicable at home to complex industrial processes used in municipal water treatment.
Chlorine is widely used because of its effectiveness in killing bacteria and viruses, ensuring safer potable water. However, its presence can result in unpleasant tastes and odors, and it may react with organic matter to form potentially harmful byproducts. Eliminating it enhances the sensory qualities of water and reduces concerns about the formation of these disinfection byproducts. Historically, various methods have been developed and refined to achieve efficient and cost-effective removal, reflecting ongoing advancements in water treatment technology.
