The significance of residual chlorine in water to understand2

Residual chlorine is one of the most special detection indicators in tap water, because it is a substance added to tap water artificially, and it is a substance that must be added but cannot be added in excess. Its main function is to inhibit the number of bacteria in the process of water delivery, which will be consumed over time. However, in actual situations, due to various situations, the residual chlorine in tap water will disappear or be too high, causing water trouble. Because the pipe network is too long or the pollution is serious, the residual chlorine in tap water will disappear too quickly, and it will not have the effect of inhibiting bacteria. At this time, it needs to be supplemented artificially, and often due to the lack of necessary detection tools in the process of supplementing, Adding based on personnel experience will cause excessive residual chlorine. The most direct problem when residual chlorine is excessive is that the water has a strong chlorine smell. In addition, some organic matter in the water may chemically react with residual chlorine to form toxic and harmful chemicals. At the same time, in industrial water treatment, excessive residual chlorine will accelerate the damage of water treatment equipment and increase production costs. Whether it is in domestic life or industrial application, as long as tap water is drawn, the detection of residual chlorine is necessary. Since residual chlorine is a basic indicator of tap water, its detection method is relatively complete, and a complete detection method is provided in GB5750-2006. At the same time, since residual chlorine detection is a basic water quality indicator of tap water, it is of great significance. A variety of detection tools are also provided, including instruments, kits, test strips, etc. Users can choose different products according to actual needs and measurement ranges.
