Where and who use UV water sterilization ?
UV water sterilization. More than 3,000 drinking water facilities in Europe use UV water sterilization. The relatively large-scale ones include the Rotterdam Water Plant in the Netherlands (470,000 m 3 /d), the St. Petersburg Water Plant in Russia (860,000 m 3 /d), and the Styrum in Germany. Ost Water Plant (192,000 m 3 /d). In North America, due to the strict regulations on cryptosporidium , giardia and disinfection by-products in the new drinking water standards , ultraviolet technology has received unprecedented attention.
How UV water sterilizer works?
1.) Sterilized water
2.) Pre-treated water
The U.S. Environmental Protection Agency (EPA) quickly established the application standard of ultraviolet technology in drinking water treatment after researching that ultraviolet light is the most effective and feasible technology for controlling Cryptosporidium and Giardia. The second phase of the enhanced surface water treatment regulations (LT2ESWTR) announced in 2006 in the United States stipulates that 310g of Giardia, 410g of virus, and 410g of Cryptosporidium must be removed or inactivated during drinking water treatment. Since chlorine disinfection has almost no effect on cryptosporidium, LT2ESWTR requires existing water plants to use filtration plus ultraviolet or ozone disinfection processes, while new water plants need to use filtration and multi-stage combined disinfection processes. Large-scale water supply plants in North America that use ultraviolet disinfection include the Chicago Middle Lake Water Plant (180,000 m 3 /d), Seattle Water Plant (680,000 m3/d), and Vancouver Victorial Water Plant (510,000 m 3 /d). Montreal Water Plant (3 million m 3 /d), etc.
The aforementioned pathogenic microorganisms occurred in the Walkerton Water Plant in Ontario, Canada in 2000UV disinfection technology was also used after the infection. The U.S. New York tap water UV disinfection system under construction has a processing capacity of 8.36 million m 3 /d, which is the world’s largest drinking water UV sterilizer project. According to statistics, there were no cases of using ultraviolet disinfection systems in large and medium-sized water plants in the United States in 2000, but by 2006 the proportion of large and medium-sized water plants using ultraviolet disinfection had risen to 10%. More UV projects are under construction or have been put into use. The application of ultraviolet technology to the disinfection process of drinking water represents the development trend of disinfection technology in the world.

The use of UV water sterilization in different regions
Different regions have different combinations of UV water sterilization. The UV sterilization process has many advantages and disadvantages. The main disadvantage is that it does not have the ability to maintain continuous disinfection of the pipe network. There are certain differences between the use of UV disinfection technology in Europe and North America. In some European water plants in the Netherlands, Austria , Germany and other places, drinking water is disinfected by ultraviolet rays directly into the water supply pipe network. According to statistics, most water plants in the Netherlands use ultraviolet light for disinfection alone, and there is no residual chlorine at the end of the pipe network. The reason is that the pipe network in Europe is in good condition, the pipe network system is relatively small, and the bio-assimilable organic carbon in the water is low. In order to prevent residual chlorine from producing disinfection by-products in the pipe network, ultraviolet disinfection is often used alone.
