Chlorine disinfection
a) General: Chlorination will be used for disinfection of potable water in all cases with the exception of individual or small unit water purification for which iodine tablets may be used.
b) Efficiency: The efficiency of chlorine disinfection is affected by the following variables:
1) A combination of the form of chlorine present, the pH of the water, and the contact time.
As the pH of the water increases from 5 to 9, the form of the chlorine residual changes from hypochlorus acid (HOCI) (the most effective form) to hypochlorite ion (OCI -) which is less effective.
The most effective disinfection occurs when the pH is between 5.5 and 6.5.
At the same pH, a longer contact time also results in increased disinfection.
2) The type and density of organisms present (virus, bacteria, protozoa, helminth, or others) and their resistivity to chlorine.
Bacteria are the most susceptible to chlorine disinfection whereas the cysts of the protozoa Entamoeba histolytica and Giardia lamblia are the most resistant.
3) The temperature of the water.
At lower temperatures microorganism kill tends to be slower, and higher chlorine residuals or longer contact times are needed.
4) The concentration of substances other than disease-producing organisms that exert a chlorine demand.
During disinfection, chlorine demand can be exerted by chemical compounds such as those containing ammonia and organic material.
Many of these compounds are not effectively removed in conventional water treatment processes and may be present to exert chlorine demand during disinfection.
