Xylem Expands UV Treatment for Aquaculture Industry

The systems will be showcased at the Aqua Nor trade show in Trondheim, Norway, Aug. 13 to 16, 2013

Xylem has expanded its range of Wedeco ultraviolet (UV) disinfection solutions specifically designed for the tank-based aquaculture industry. Xylem’s new, closed-vessel Wedeco BX and Quadron series UV systems are designed for inactivating fish pathogens and produced in duplex stainless steel capable of resisting the corrosive effect of saltwater. The new Wedeco units will enable customers to handle pressurized flows ranging from 10 to more than 4,000 cu meters per hour. Xylem has also added new systems made of saltwater resistant polyethylene (HDPE) to its Wedeco BX series and TAK Smart open channel solution.

The systems will be showcased at the Aqua Nor trade show in Trondheim, Norway, Aug. 13 to 16, 2013.

“These new systems expand the Wedeco UV portfolio designed to meet the specific needs of the aquaculture industry,” said Wolf Meese, business development manager for Xylem. “The duplex stainless steel reactors allow us to offer solutions with higher flow rates that require a minimum of energy and space to operate.”

Aquaculture is the most rapidly growing sector of food production worldwide. Higher fish density can lead to pathogen increase, which is a significant threat to aquaculture operations. According to a 2012 “World Review of Fisheries and Aquaculture” report, “disease outbreaks in recent years … have affected farmed Atlantic salmon in Chile, oysters in Europe and marine shrimp farming in several countries in Asia, South America and Africa, resulting in partial or sometimes total loss of production.” Disinfection by UV or ozone can reduce the risk of disease in aquaculture systems and results in less need for vaccination, higher growth rates and decreased mortality.
