Factors affecting Bactericidal efficiency of Chlorine
1. Turbidity: The effect of turbidity in water is to make it difficult to obtain free residual chlorine. Also, the penetration of chlorine and therefore the destruction of bacteria in particles of suspended matter of a turbid water may be very uncertain.
2. pH of water: Increasing pH reduces effectiveness of chlorine. The effective sterilising compound, hypochlorous acid, is formed in greater quantities at low pH than(5 to 7) at high pH values.
3. Time of Contact: Bactericidal efficiency of chlorine increases with increases in time of contact in general also the bactericidal activity of chlorine is not spontaneous.
