2.5.2.3. Super Chlorination

The chlorine dosage applied is much greater than that of marginal chlorination. The chlorine dosage depends on the character of the water and the purpose for which the water is used. A considerable amount of chlorine may be present after a given contact period. Therefore, for certain purposes, the water is dechlorinated. Super chlorination includes break-point chlorination and in-plant chlorination.
