BIOCIDES
A
biocide
is a chemical substance capable of killing living organisms,
usually in a selective way.
Some substances used as biocides are also employed as
anti-fouling agents or disinfectants under other circumstances:
chlorine, for example, is used as a short-life biocide in
industrial water treatment but as a disinfectant in swimming
pools.
Biocides are usually slug fed to a system to
bring about rapid effective population reductions from which the
microrganisms cannot easily recover. There are various different
biocides, some of which have a wide range of effect on many
different kinds of bacteria. They can be divided up into
oxidising agents and non-oxidising agents.
Oxidising agents:
Chlorine
Chlorine dioxide
Hypochlorite
Ozone
Non-oxidising agents:
Dibromopropionide
Isothiazalone
Gluteraldehyde
Bronopol
Quaternary ammonium salts
In many cases oxidising agents are not
effective biocides. Non-oxidising agents are then applied.
