Those who are looking for an answer to the question «Why chlorine is used for water purification using?» often ask the following questions:

❔ Why is chlorine used in water purification?

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.

❔ 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.

❔ Why is chlorine used in water purification device?

Chlorination involves adding a measured amount of chlorine to water to produce a residual sufficient to kill bacteria, viruses, and cysts. The killing effect of chlorine depends on the pH of the water, temperature, chlorine level and contact time (i.e., the time the chlorine is in the water before consumption).

Chlorine has been used for over a century as a primary water disinfectant and is largely responsible for elimination of water-borne diseases such as typhoid and dysentery in developed countries. Unfortunately, chlorine reacts with many organic compounds to form chlorine disinfection by-products that are recognized as potent carcinogens at low levels of concentrations.

Chlorine has now been a major part of municipal water treatment for nearly 100 years. About 98% of municipal water treatment facilities now use chlorine disinfectant as their disinfectant of choice, and about 200 million U.S. residents receive chlorinated drinking water through their home faucets (Christman, 1998).

Chlorine has been used for applications, such as the deactivation of pathogens in drinking water, swimming pool water and wastewater, for the disinfection of household areas and for textile bleaching, for more than two hundred years.

Chlorine was the gas of choice earlier for water purification treatments, due to its water-solubility and germicidal properties. Chlorine dioxide is ten times more soluble in cold water than chlorine making it more effective in any chlorine-related applications. 👉 An effective Biocide

The most common use of chlorine in water treatment is to disinfect water. As a disinfectant, it has drawbacks, but it also has advantages. Other methods of disinfection such as ultraviolet and ozonation are effective disinfectants but they do not provide a residual to prevent pathogen regrowth as chlorination does.

Chlorine was used to disinfect the water supply. It was John Snow that successfully used it. Later in 1879 that William Soper used chlorinated lime to take care of typhoid patients. Because of too many outbreaks and casualties (from the outbreak), permanent water chlorination was implemented.

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.

Importantly, waste water treatment facilities use chlorine disinfectants to destroy oxygen-robbing contaminants in wastewater, helping to preserve the quality of our nation’s rivers and streams into which the treated wastewater is discharged.

Water chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill bacteria, viruses and other microbes in water. In particular, chlorination is used to prevent the spread of waterborne diseases such as cholera, dysentery, and typhoid .

However, chlorine in water is over three times more effective as a disinfectant against Escherichia coli than an equivalent concentration of bromine, and over six times more effective than an equivalent concentration of iodine. Iodine is commonly used for portable water purification, and bromine is common as a swimming pool disinfectant.
