What is the mechanism of action of chlorine?
What is chlorine’s mechanism of action? The health effects of chlorine are primarily due to its corrosive properties. The strong oxidizing effects of chlorine cause hydrogen to split from water in moist tissue, resulting in the release of nascent oxygen and hydrogen chloride which produce corrosive tissue damage.
What are the methods of chlorination?
The different types of chlorine disinfection are batch disinfection, simple chlorination, super-chlorination followed by dechlorination, and shock chlorination. They vary in the amount of chlorine used.
What is the process of chlorination of water?
What is chlorination? Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and viruses. Using or drinking water with small amounts of chlorine does not cause harmful health effects and provides protection against waterborne disease outbreaks.
What is chlorination short answer?
chlorination is the process of adding chlorine or chlorine compounds such as sodium hypochlorite to water. This method is used to kill certain bacteria and other microbes in tap water as chlorine is highly toxic.
What is the bleaching action of chlorine?
Chlorine bleaches by the process of oxidation as it needs moisture for its bleaching action. When chlorine reacts with water to form hydrochloric acid, which is unstable and quickly dissociates to form nascent oxygen. Nascent oxygen is a more powerful oxidising agent.
How does chlorine disinfection work?
Chlorine is currently employed by over 98 percent of all U.S. water utilities that disinfect drinking water. Researchers postulated that chlorine, which exists in water as hypochlorite and hypochlorous acid, reacts with biomolecules in the bacterial cell to destroy the organism.
What is chlorination explain the various stages of chlorination?
Chlorination is the application of chlorine to the water for the purpose of disinfection. During pre-chlorination, chlorine is usually added to raw water after screening and before flash mixing. Post-chlorination, in contrast, is often the last stage in the treatment process.
What is the pH of chlorine?
When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH.
What is sterilization of water?
The process of killing, inactivating, or removing microorganisms (bacteria, viruses, etc.) from a quantity of water. The normal methods of sterilization involve agents such as heat, chemicals, or radiation.
What is meant by chlorination and aeration?
Chlorine and aeration combined into one powerful unit will treat iron, iron bacteria, sulfur, sulfate reducing bacteria, manganese, algae, tannins, arsenic, and low pH. It can greatly add to your water flow rate and and gives you a constant flow in your home much like city water.
What is break point chlorination?
Breakpoint chlorination is a technique used to remove combined chlorine by adding free available chlorine. To reach breakpoint, sufficient chlorine must be added to the pool to raise the free available chlorine level to 10 times the amount of combined chlorine.
Why does chlorine act as a bleaching agent?
Hint: Chlorine can act as a bleaching agent due to the nascent oxygen it can produce in the reaction with water. Basically, one Cl atom gets oxidised and the other gets reduced when chlorine gas reacts with water. Complete answer: Thus, it bleaches the material.
