Biocides represent chemical agents and formulations to control and eliminate harmful microorganisms. An appropriate biocide protocol is important in treating waters in use for Industrial, Commercial and Domestic applications in system maintenance programs.

Biocides by their name are chemicals designed to kill all sizes and life stages of organisms, especially microorganisms, and the effectiveness of biocides varies with the type chosen and concentration of a biocide with the duration of the exposure. Species that are exposed to sub-lethal concentrations, or for too short of time may be damaged but survive and or mutate.

Biocides are produced in liquid, powdered and solid (tablet ) form, in ready-to-use formulations or as concentrates and are applied using a variety of techniques.

Biocides also may be described by their action type :-

OXIDISING BIOCIDES the most employed type which are used in water treatment.

• Chlorine and deriatives ( hypochlorous acid, bleach, etc ), chlorine dioxide,
• Bromine and derivatives ( activated bromides, stabilised bromine chlorides and Hypobromites, etc )
• Hydrogen Peroxide
• Peracetic acid
• Ozone 

NON-OXIDISING BIOCIDES used in industrial applications for specific actions

• Isothiazolones (CMIT, MIT)
• Quat compound ( ADBAC, DDAC, THPS, DBNPA, etc)
• Glutaraldehyde, ormaldehyde
• Benzalkonium Chloriode

The above can also be coupled with Dispersants and Enzymes which are non biocidal surface action agents that penetrate and loosen the deposits formed. The biocides act with these microorganisms Iiving in any biofilm and assist in their elimination.
