Disinfect

To free from infection by either a chemical or physical means; causing the absence of pathogenic or indicator coliform bacteria in drinking water. Disinfectants kill or inactivate 99.9 to 99.9999 percent (but not 100%) of microorganisms under controlled conditions. Some common disinfectants are the halogens: chlorine, iodine, bromine, and hypochlorites; ozone, potassium permanganate, hydrogen peroxide, peracetic acid; formaldehyde, glutaraldehyde, phenol (carbolic acid), organic acids, benzoic and salicylic acids and their sodium salts, high pH, heat, ionizing radiation, and electromagnetic waves such as those of ultraviolet light. The USEPA requires that a disinfection claim must show killing or inactivation of all vegetative microbes in 10 minutes.
