❔ Water purification methods chlorine?

Chlorine is typically added to water using chemical feed systems to inject liquid sodium hypochlorite (bleach) solution or added as gaseous chlorine (typical of larger public water treatment plants). Chlorine cannot be used in most high purity water loops without contaminating the process or interfering with the end use of the water. These systems often rely on ultraviolet disinfection as an alternative to water chlorination.

Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses. Different processes can be used to achieve safe levels of chlorine in drinking water. Using or drinking water with small amounts of chlorine does not cause harmful health effects and provides protection against waterborne disease outbreaks.

Any type of chlorine that is added to water during the treatment process will result in the formation of hypochlorous acid (HOCl) and hypochlorite ions (OCl-), which are the main disinfecting compounds in chlorinated water. More detail is provided later on in this fact sheet.

Chlorine and chlorine-based compounds are the only disinfectants that can efficiently kill microorganisms during water treatment, and maintain the quality of the water as it flows from the ...

The filter beds are cleaned periodically by pumping clean water backwards through the filter. Chlorination – chlorine gas is injected into the water to sterilise it. The chlorine is poisonous and...

The mixture will produce a chlorine solution of approximately 500 milligrams per liter. To disinfect water, add one part of the chlorine solution to each 100 parts of water you are treating. This is about the same as adding 1 pint (16 ounces) of the chlorine solution to 12.5 gallons of water.

As a halogen, chlorine is a highly efficient disinfectant, and is added to public water supplies to kill disease-causing pathogens, such as bacteria, viruses, and protozoans, that commonly grow in water supply reservoirs, on the walls of water mains and in storage tanks.

Chlorine readily combines with chemicals dissolved in water, microorganisms, small animals, plant material, tastes, odors, and colors. These components "use up" chlorine and comprise the chlorine demand of the treatment system. It is important to add sufficient chlorine to the water to meet the chlorine demand and provide residual disinfection.

Water may contain microorganisms that can cause diarrhea, vomiting and even death. Water purification systems kill these microorganisms to make the water safe to drink. There are a number of ways water is purified to make it safe, such as boiling, chemical treatment with chlorine or iodine, and filtration systems. Removal of Toxic Metals

Chlorine is an effective water purification method that kills germs, parasites and other disease-causing organisms found in ground or tap water. Water can be purified using chlorine tablets or liquid chlorine. As an off-the-shelf water purification product, chlorine is cheap and effective.

Chlorine is added to water to make it safer to store and transport. Once the chlorine has been removed, the water should be used as soon as possible, or kept refrigerated, capped or covered, because it no longer has the defense, or disinfecting, mechanism to fight off stray bacteria or viruses, some of which are in the air we breathe.

In addition to providing a residual, adding chlorine to water will also: oxidize iron, manganese, taste and odour compounds, remove colour in the water, destroy hydrogen sulphide, and aid other water treatment processes, such as sedimentation and filtration.

Many municipalities add chlorine to their water to help kill harmful organisms such as viruses and bacteria that could make us sick if we ingested them. This disinfecting ability is also why swimming pool facilities add chlorine to their water.

In addition to disinfection, chlorine can be effectively used to oxidize iron, manganese and hydrogen sulfide to facilitate their removal, to reduce color in water, and to aid in such treatment processes as sedimentation and filtration.

While chlorine is often associated with swimming pools, when used in moderate amounts, it can make water potable by eliminating bacteria and viruses. Chlorine is widely used in purifying water at municipal levels, making water safe for drinking for a city’s population.
