Short Note on Chlorination Practices

Chlorination Practices :

There are generally two practices as explained below :-

(i) Plain chlorination : This is applied where water is relatively less polluted and sufficient contact period of at least 30 minutes between the point of chlorination and consumer point is available.

(ii) Super chlorination : This is adopted in case of water being heavily polluted or where available contact period is short i.e. less than 30 minutes. In case of super chlorination, it may be necessary to go in for dechlorination to remove the excess residual chlorine.
