Dechlorination
For some applications, chlorine in water is intolerable. For
example, a bacteriology laboratory cannot allow a killing agent in
its media. Municipal water must also be dechlorinated if it is to
be used in the manufacture of products such as photographic
emulsions. Chemicals commonly used for removal of chlorine are
those that are easily oxidized;
SO
,
NaHSO
,
Na
SO,
and Na
S
O are examples. Activated
carbon is quite good for adsorbing chlorine, and carbon columns are
a major option when designing a dechlorination system.
