Raw water contains certain impurities, heavy metals, sediment, harmful substances and organic pollutants. Diseases caused by poor drinking water quality: digestive diseases, infectious diseases, various skin diseases, diabetes, stone disease, cardiovascular disease, cancer, etc. There are more than 50 kinds, and now with the accelerated pace of life, people pay more and more attention to the precious time, and want to solve the problem of drinking water in the shortest time. Then comes the much-loved water purifier, because it is not only convenient, but also purifies unclean water into drinkable water. Is a water purifier really a foolproof choice?
Why do you need UV germicidal lamps?
The function of the water purifier is to remove the residual heavy metals, sediment, organic pollutants, residual chlorine and other substances harmful to the human body through the filtration and adsorption of various filter elements; especially the reverse osmosis water purifier, which can filter 98% impurities in water. Using this filtration method, the water quality is improved, so as to obtain pure water that can be directly drunk.
But if the water purifier is used for a long time and the bacteria in the pipeline exceeds the standard,what will cause such a result?
Many water purifiers are used at home, and for a long time they forget to replace the filter element on time, and the secondary pollution that is easy to produce, bacteria is easy to grow and reproduce; at the same time, the pipeline will inevitably be contaminated by bacteria for a long time. Therefore, adding ultraviolet germicidal lamps to the last effluent of the water purifier can effectively kill the bacteria parasitic in the water, and at the same time ensure that the water that comes out is sterile and fresh.
For traditional disinfection techniques such as chloride or ozone, the disinfectant itself is a highly toxic and flammable substance, while ultraviolet disinfection does not have such a safety hazard. It is time-consuming and energy-consuming, and it only needs a little electricity, which makes people feel more at ease.
The advantage of ultraviolet sterilization technology is that it has a broad-spectrum sterilization ability. Generally, it can achieve a sterilization rate of 99%-99.9% for bacteria and viruses in 0.2 seconds to 2 seconds, and can easily kill viruses, staphylococcus, and coliform bacteria. , Salmonella, Legionella (LEGIONELLA), Pneurnophila, Shigella, and many other bacteria. It can kill almost all bacteria and viruses with high efficiency, and there is no need to worry that the water filtered by the water purifier will contain bacteria that are harmful to the human body. In addition, ultraviolet sterilization is pure, and there is no secondary pollution.
