Chlorination is necessary to prevent epidemics of waterborne diseases.
Produced by the electrolysis of brine.
When added to water, chlorine breaks down into hypochlorous acid, a powerful oxidant and disinfectant.
Stable element – when stored in sealed containers it has an indefinite shelf-life.
Key advantage of the use of chlorine in water treatment is its ability to persist in treated water. Its residual effect protects water from microbiological contamination when passing through lengthy networks.
