Xylem will supply technology for Sweden's largest UV disinfection facility for drinking water

Xylem has won a contract to provide ultraviolet (UV) drinking water treatment solutions to the largest UV disinfection project ever undertaken in Sweden. The Xylem solutions will help deliver clean, treated drinking water to 900,000 people across 16 municipalities. The facility will have the capacity to handle a potential 25% increase in water volume to support future population growth.

Xylem will provide four Wedeco K- Series UV disinfection systems, to upgrade the Sydvatten AB Waterworks in the Scania (Skåne) region in southern Sweden. Xylem’s UV systems were chosen for their flexible design, low lifecycle costs, negligible environmental impact and ability to handle large volumes of water in an efficient manner, while catering to potential future plant expansion.

The Wedeco K143 systems each feature 13 rows of 12 UV lamps and will treat a total of 4,300 cu meters of water per hour. The vessels were designed with installation and future expansion in mind by having the various sections bolted rather than welded together. This met the requirement of having no section longer than 2.5 meters and allows the possibility of adding another section of lamp rows at a later date. In this way the solution is future-proofed to cater for increased demand as the population grows.

Ron Port, head of Xylem’s treatment business said, “Being involved in developing the largest UV disinfection facility in Sweden is further evidence of our world-leading expertise in UV and ozone water treatment. Our advanced, environmentally friendly technologies will help to address challenges at Sydvatten AB Waterworks and will deliver chemical free, clean and safe water for almost one million people in southern Sweden.”

Xylem is working on this project together with their Swedish Representative—Christian Berner AB—which led the tender process.

Per-Erik Ålander, area manager at Christian Berner said, “The innovative design of Xylem’s Wedeco K143 system as well as their renowned expertise in UV water treatment makes Xylem the perfect partner for this project. The system design will ensure that significant plant expansions can be carried out easily and cost-effectively.”

The Sydvatten AB Waterworks drinking water treatment plant has been in operation since 1966. Xylem’s Wedeco UV Systems will complement existing traditional treatment methods to eliminate bacteria, viruses and parasites.
