Sweden’s Largest UV Disinfection Facility Equipped by Xylem Systems
In response to a potential 25 percent increase in water volume due to future population growth, Sweden recently awarded Xylem a contract to supply ultraviolet (UV) drinking water treatment systems to its current facility in southern Sweden. This will be the largest disinfection project ever attempted in the country.
Xylem will provide four Wedco K-Series UV disinfection systems to upgrade the Sydvatten AB Waterworks facility, which has been in operation since 1966. These solutions will be used alongside traditional treatment methods to eliminate bacteria, viruses, and parasites and transport clean, treated water to more than 900,000 people throughout 16 municipalities.
The Wedeco K143 UV systems each feature 13 rows of 12 UV lamps able to treat a total of 4,300 cubic meters of water per hour. Several features make the Xylem K143 systems ideal for this operation, including their flexible and innovative design, low lifecycle costs, negligible environmental impact, and ability to efficiently handle large volumes of water.
With the possibility of expansion in mind, the Wedco K143 systems were designed to be bolted rather than welded together, creating the option of additional lamps installations as they become necessary while meeting the requirement of having no section longer than 2.5 meters. Xylem’s solution recognizes and adapts to Sweden’s inevitable population growth to protect against the higher costs associated with continually upgrading or replacing facility equipment in the future.
“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,” says Ron Port, head of Xylem’s treatment business. “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 with its Swedish Representative, Christian Berner AB, which led the tender process
“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,” says Per-Erik Ålander, area manager at Christian Berner. “The system design will ensure that significant plant expansions can be carried out easily and cost-effectively.”
