Chitin and its derivatives have two major properties
that are of interest for industry and for nature
conservation: they are remarkable chelation agents
and heavy metal traps.
Employed as a chelation agent, chitin and its
derivatives are used for treating drinking water
by separating organic compounds and heavy metals, and for
treating sewage by precipitating certain anionic
wastes and capturing pollutants such as DDT and PCBs
(polychlorobenzene).
The Environmental Protection Agency (EPA) has already
approved the use of chitosan in water at concentrations
of up to 10 mg per litre. For sewage treatment, chitosan
can be used at up to 5 ppm. It reduces the oxygen demand
by 80 to 85% and reduces the phosphates level to less
than 5 ppm.
