DECHLORINATION

Definition

The process by which chlorine (acting as an anti-microbial agent) is removed from water before being used as culture water. This can be carried out by aeration of the water. It is also used in microbial analysis of water samples to ensure accurate readings. Dechlorination can also be carried out by the addition of reducing agents (Sodium thiosulphate, Sodium sulphite, Sodium arsenite) to the water sample and/or sample container.
