The water source used for urban water supply is generally surfacewater or groundwater, which is more or less polluted by domestic sewage and industrial wastewater, even through coagulation and precipitation, filtration and other purification treatments, but also can not remove harmful bacteria, pathogenic bacteria and other microorganisms completely. At the same time, drinking water in the transportation and storage process, may also be contaminated by bacteria. In order to prevent the spread of waterborne diseases, disinfection treatment must be used to control the elimination of waterborne pathogenic bacteria, viruses and other pathogenic germs spread the problem.

  Since 1897, when chlorine was first used to disinfect water supply networks in the United Kingdom, chlorine has remained the disinfectant of choice in waterworks. When chlorine is added to water, hypochlorous acid and hypochlorite are formed, and the main component of chlorine that can play a disinfecting role is hypochlorous acid. Hypochlorite is a very small neutral molecule, which can easily diffuse to the surface of negatively charged bacteria and pass through the bacterial wall to the inside of the bacteria, where its oxidizing effect destroys the bacterial enzyme system, which is a catalyst for glucose uptake and metabolism, and thus kills the bacteria.

  Producing sodium hypochlorite in site is efficient, convenient, economical and safe.

 Good disinfection

  The residual chlorine formed by the sodium hypochlorite solution has the ability to provide continuous disinfection and maintain water sanitation for a long period of time.

 High dosing accuracy

  Sodium hypochlorite solution is dosed in a low-concentration liquid form, allowing for accurate control of the dosage.

 High security

  Sodium hypochlorite solution is produced and used in site, which is relatively safe and does not lead to secondary contamination such as chlorate and bromate.

Good economics

  Sodium hypochlorite solution is less expensive to produce than other chlorine-based disinfectants (liquid chlorine, finished sodium hypochlorite, chlorine dioxide).
