UV units as hygienic barrier in drinking water

Reference ID: 140330
Industry: Waterworks
Application: Drinking water

In many countries the drinking water regulations require two independent hygienic barriers, such as UV disinfection systems. In Denmark, UV systems have often been used in places where you have - or have had - specific problems with microbial contamination. In the city of Odense, this has not been the case. The UV system is here of a purely preventive nature, set up on waterworks and in advanced locations in the pipeline network, a total of 11 sites. VandCenter Syd is one of Denmark's largest and oldest water utilities. The drinking water supply consists of six waterworks, nine pumping stations and two water towers. Each year, more than nine million cubic meters of clean drinking water is supplied to 171,000 consumers. SILHORKO-EUROWATER has supplied and installed all the UV plants and has entered into a long-term maintenance agreement.
