Xylem has won a contract to provide ultraviolet (UV) drinking water treatment solutions to the largest UV disinfection project ever undertaken in Sweden.
Xylem says that the 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 WEDECO K143 UV systems were chosen for their flexible and innovative design, low lifecycle costs, negligible environmental impact and ability to handle large volumes of water in the most efficient manner possible, 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 cubic metres 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 metres 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.
