Chlorine-releasing compounds - Wikipedia

Chlorine-releasing compounds, also known as chlorine base compounds, are a family of chemicals that release chlorine. They are widely used to disinfect water, medical equipment, and surface areas as well as bleaching materials such as cloth. The presence of organic matter can make them less effective as disinfectants. They come as a liquid solution, or as a powder that is mixed with water ...

Water Chlorination/ Chloramination Practices and Principles

Water disinfection, as now ordinarily considered, involves specialized treatment for the destruction of harmful, and otherwise objectionable, “nuisance” organisms. Classically, disinfection processes have been employed to destroy or inactivate dis-ease-producing (pathogenic) organisms—more particularly bacteria of intestinal ori-gin.

The conditions necessary to attain disinfection with quats depend on concentration and contact time. Typical end-use concentrations will have from 0.05 to 0.2% quat, and require 10 min to achieve disinfection. The primary interaction between quaternary ammonium compounds and bacteria is electrostatic in nature.

Water chlorination - Wikipedia

History. In a paper published in 1894, it was formally proposed to add chlorine to water to render it "germ-free". Two other authorities endorsed this proposal and published it in many other papers in 1895. Early attempts at implementing water chlorination at a water treatment plant were made in 1893 in Hamburg, Germany.In 1897 the town of Maidstone, England was the first to have its entire ...
