Chlorine or chloramine levels up to 4 milligrams per liter (mg/L), or 4 parts per million (ppm), are considered safe in drinking water. These low levels kill harmful germs and are unlikely to make people sick.
Fact sheet on disinfection, one of the primary mechanisms for the inactivation or destruction of pathogenic organisms. Contains information on how to use chlorine as a disinfectant for municipal wastewater.
The application of chlorine in disinfection process reduces the microbial risk but poses chemical risks by producing by-products dependently of bactericidal agent used. Disinfection by-products (DBPs) are formed when chlorine reacts with organic matter (NOM), and/or inorganic substances (i.e. bromide, iodide).
Chlorine and Chlorine Compounds Overview. Hypochlorites, the most widely used of the chlorine disinfectants, are available as liquid (e.g., sodium hypochlorite) or solid (e.g., calcium hypochlorite).
for any chlorine disinfection system. Chlorine dosage will vary based on chlorine demand, wastewater characteristics, and discharge requirements. The dose usually ranges from 5 to 20 milligrams per liter (mg/L). Table 2 describes some of the more common wastewater characteristics and their impact onchlorine. There are several other factors that ...
Today, chlorination is the most popular method of disinfection and is used for water treatment all over the world. Why do we Chlorinate our water? A large amount of research and many studies have been conducted to ensure success in new treatment plants using chlorine as a disinfectant.
Chlorine is the most widely used water supply disinfectant in the United States. Depending upon the predominant species of chlorine, hypochlorous acid, and/or hypochlorite ion, disinfection with chlorine can achieve greater than 99.9% destruction of bacteria.
Chlorine effectively kills a large variety of microbial waterborne pathogens, including those that can cause typhoid fever, dysentery, cholera and Legionnaires' disease.
When selecting the ideal cleanroom disinfectant there are many criteria to consider and a good understanding of the product characteristics is essential. Karen Rossington takes a look at the historic development and latest advancements in chlorine disinfection.
How does chlorine disinfection work? Chlorine kills pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. Disinfectants that are used for this purpose consist of chlorine compounds which can exchange atoms with other compounds, such as enzymes in bacteria and other cells.
