Urban water treatment
Drinking water sources such as groundwater, reservoir water, lake or pond water are open to contamination. Hence the appropriate treatment is necessary to remove disease-causing pathogens. Public or Municipal drinking water systems use various methods for urban water treatment water to provide safe drinking water. The typical steps involved are Coagulation and Flocculation, Sedimentation, Filtration and Disinfection.
What can Pristine Water offer to Urban Water Treatment Plants:
Pristine Water Electrochlorination systems help to generate and dose sodium hypochlorite solution at the Disinfection stage of water treatment, which is the final stage before distribution. This has two aims:
- the bactericidal effect (killing of germs, parasites, bacteria, and viruses)
- the remnant effect (prevent recontamination)
At the point when treated water travels over a significant distance, there are chances of water recontamination due to pathogens found in pipelines or possible gaps or leaks in the pipeline. This is why re-chlorinating the water is very essential at pumping stations. The treated water while leaving the treatment plant will have residual chlorine of 1 to 2 ppm. But the same gets depleted or used up when the water travels over a long distance. As the water with no chlorine travels further, it picks up pathogens that grow in it making it unsafe for consumption. To prevent the recontamination of water it is essential to inject chlorine in it at regular intervals at different points of its journey till the consumer’s tap. This system is perfect for remote locations where transporting and stocking of chemicals for disinfection is expensive. In such places, trained staff to dose these chemicals properly are also usually in short supply. Both these problems can be solved by this system which relies only on salt.
Pristine Water offers the best Sodium Hypochlorite Generators for urban water treatment which produces the required disinfectant from common salt for effective disinfection.
