What are the benefits and risks of water chlorination? Chlorination is the process of adding chlorine to drinking water to disinfect it and kill germs. Different processes can be used to achieve safe levels of chlorine in drinking water.

Purification of drinking water containing pathogenic microorganisms requires specific treatment called disinfection.

Although several methods eliminate disease-causing microorganisms in water , chlorination is the most commonly used. To use the chlorination metho families add one full bottle cap of the sodium hypochlorite solution to clear water (or caps to turbid water) in a standard sized container, agitate, and wait minutes before drinking. During the treatment process, chlorine is added to drinking water as elemental chlorine ( chlorine gas ), sodium hypochlorite solution or dry calcium hypochlorite. When applied to water, each of these forms “free chlorine ,” which destroys pathogenic (disease-causing) organisms. In air, chlorine has a pungent and disagreeable odour (2).

Major uses Large amounts of chlorine are produced for use as disinfectants and bleach for both domestic and industrial purposes, and it is also widely used to disinfect drinking-water and swimming-pool water and to control bacteria and odours in the food industry (4). Disinfection of drinking water , especially when the supply originates from a surface source, is needed to maintain water quality and protect public health. The challenge is to maintain the level of microbial protection while minimizing the exposure of the consumers to DBPs.

If the chlorine liquid is released from its container it will quickly return back to its gas state. Drinking water chlorination is the addition of chlorine to drinking water systems. Chlorine gas is the least expensive form of chlorine to use. It is the most common type of drinking water disinfection. Disinfection kills bacteria, viruses, and other microorganisms that cause disease and immediate illness.

Q: How common is chlorine disinfection of drinking water ? Today, about percent of U. Please refer to the refe renced papers below for more details.

Enjoy cleaner, spring-like water from every tap in the house. Emergency Disinfection of Drinking Water. Locate a fresh liquid chlorine bleach or liquid chlorine bleach that is stored at room temperatures for less than one year. Use the table below as a guide to decide the amount of bleach you should add to the water , for example, drops of bleach, or drops of 8. During the conventional treatment process, chlorine is added to drink- ing water as elemental chlorine (chlorine gas), sodium hypochlorite solution (bleach), or dry calcium hypochlorite.

As a general guideline, drinking water should contain 2- to 3-ppm free-chlorine throughout an automated watering system. But chlorine treatment of drinking water causes disinfection byproducts (DBPs). When sodium hypochlorite (also known as “bleach” or simply referred to as “chlorine”) is added to the water, it forms trihalomethanes (THMs) with organic material present in the water. Procedure for Shock Chlorination of Wells (Adapted from NYSDOH, Don’t be Left in the Dark and Georgia’s Cooperative extension Disinfecting Your Well Water Shock Chlorination ) 1. Run water until clear, using an outdoor faucet closest to the well or pressure tank 2.
