Chlorination, ozone, ultraviolet light, and chloramines are primary methods for disinfection. However, potassium permanganate, photocatalytic disinfection, nanofiltration, and chlorine dioxide can also be used. Organic material is naturally present in water.

Currently, there are five main EPA-registered chemicals that hospitals use for disinfectants: Quaternary Ammonium, Hypochlorite, Accelerated Hydrogen Peroxide, Phenolics, and Peracetic Acid.

Chlorination is the most common disinfection method to ensure safe supply of drinking water with several advantages in terms of biocidal efficiency and efficacy, cost effectiveness and maintenance of residual concentration to safeguard regrowth of microorganisms in distribution systems (Washington State, 2004).

Chlorination, ozone, ultraviolet light, and chloramines are primary methods for disinfection.

NF T 72-281 is a French standard that establishes a method for evaluating the antimicrobial activity of materials and surfaces in hospital and similar environments. It describes methods for testing the effectiveness of antimicrobial products on surfaces using a suspension test method.

Disinfection describes a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects (Tables 1 and 2). In health-care settings, objects usually are disinfected by liquid chemicals or wet pasteurization.
