An average breakpoint chlorination curve, displaying the chemical reactions and also the residual chlorine ranges at several levels is illustrated in below figure.
The "chlorine desire" with the water is outlined in different ways in different publications, which is both the chlorine necessary for the 1st irreversible reaction, or for the check here 1st irreversible reaction in addition to the second, reversible, reaction.
But ozone, if it was more affordable or basic to manage, ozone might be better than chlorine For lots of apps.
Of the two, hypochlorous acid is the simplest. The amount of Each individual compound present from the water is depending on the pH level of the water before addition of chlorine. At reduce pH concentrations, the hypochlorous acid will dominate. The mix of hypochlorous acid and hypochlorite ions can make up what is termed ‘absolutely free chorine.
Some pathogens present in surface water are proof against normal doses of chlorine but They're more likely to be removed if acceptable therapy (e.g. fine filtration) is furnished prior to chlorination.
