   Why is chlorine most widely used in water treatment?

 Chlorine and its compounds are the most produced and consumed chemicals in the world for many purposes such as sterilization, white pipes, cleaning,…. Hundreds of years ago, chlorine was used as a water treatment agent. With the advantage of high disinfection efficiency, low cost and less danger to the user, chlorine disinfection is still the most widely used method to treat drinking water, swimming pool water and water. waste.

     NATION LAB offers a wide range of chlorine meters. From chemical test kits (CTK), portable optical meters to single-parameter, multi-parameter and desktop meters NATION LAB provides the equipment for you to take accurate, affordable measurements for virtually every residual and total chlorine measurement application ...

     What is residual chlorine? What is total chlorine?
    Excess chlorine is the available chlorine, such as hypochlorous acid (HClO) and hypochlorite (ClO-), added to water to disinfect. When excess chlorine combines with pollutants, it becomes combined chlorine, also known as chloramine. Once chlorine is combined, it reduces its sanitizing capacity. The content of total chlorine will always be higher than residual chlorine, since it is the sum of both residual chlorine and combined chlorine. Therefore, the residual chlorine content is a direct indicator of the effectiveness of the disinfectant solution.
      Why is it necessary to control chlorine content in water?
      Although it is less dangerous to the user, if the concentration of chlorine exceeds the permitted level, it still causes discomfort for some people who are sensitive to chlorine. The high chlorine content causes an unpleasant pungent odor and can irritate the eyes and skin; Chronic inhalation of chlorine can damage a child's respiratory system. The high residual chlorine makes the fabric quickly fading, tearing down, making the soap not foamy, leading to a lot of soap consumption. High chlorine concentrations corrode equipment and pipes.
High levels of chlorine in the water can cause breathing problems, headaches, and skin and eye irritation

    However, the concentration of chlorine in the water is too low, it is not really good, if the excess chlorine in the water is zero, it cannot guarantee that harmful microorganisms that exist in the water have been completely destroyed, the residual chlorine content is too low. is not enough to keep the water from re-contaminating the bacteria until use.

     According to the National Technical Regulation on drinking and domestic water quality, the allowable residual chlorine concentration in water is 0.3-0.5mg / l, while it takes up to 1000ppm or more to start causing danger.
