Method and Arrangement for a Water Treatment

United States

9279264

March 8, 2016

The present invention relates to water treatment by chlorine disinfection. A chlorine stabilizer is dosed into water to be treated as far as a predetermined chlorine stabilizer concentration in said water is achieved. As soon as the pre-determined chlorine stabilizer concentration is achieved said achieved chlorine stabilizer concentration is maintained in said water constant. A chlorine disinfectant concentration is adjusted in said water to be treated to a predetermined chlorine disinfectant concentration in said water by dosing a non-stabilized chlorine disinfectant (free chlorine) into said water to be treated .Therefore the invention combines advantages of free chlorine and stabilized chlorine disinfection with facilitating to re-duce DBPs at low chlorine stabilizer concentrations in water without compromising disinfection safety.
