Abstract

The quality of drinking water is a factor of vital importance in public health. Much of the ill health in. the under developed coun­tries is largely due to lack of safe drinking water. There can be no state of positive community health and well being without safe water supply (Giroult, 1977).

Chlorination is one of the greatest adva­nces in water purification. Chlorine kills pathogenic bacteria and in high doses dest­roys the bacterial spores and viruses. It oxidizes iron, mangnese and hydrogen sulphide. It also destroys some taste and odour producing constituents in the water (WHO, 1976'.

Chlorine demand is the amount of chlorine that is needed to destroy bacteria and to oxidize all the organic matter and ammoniacal substances present in the water. If further chlorine is added beyond this point, free chlorine begins to appear in the water.
