Wedeco was founded in 1976 in Herford, Germany to develop chemical-free and environmentally friendly water treatment technologies, including ultraviolet light and ozone systems. There are more than 250,000 installed Wedeco systems for UV disinfection and ozone oxidation globally in private, public utility and industrial locations. Wedeco introduced ozone technology in 1988 and has been expanding internationally ever since. UV disinfection systems have a number of applications including water treatment and aquaculture. Ozone disinfection systems have applications in drinking water, wastewater, process water, product polishing, bleaching, ozonolysis / synthesis and deodorization.
Wedeco UV systems offer customers an alternative to environmentally-harmful chemicals used for disinfection including chlorine, chlorine dioxide, and hypochlorite. UV disinfection is adapted from the natural action of sunlight and is extremely versatile. UV light can be used for disinfecting water, destroying harmful microorganisms in other liquids, on surfaces, and in the air. Wedeco UV systems are suited for the disinfection of drinking water, process water, wastewater, salt water, ultrapure water, and other translucent fluids, such as sugar syrup.
Ozone is one of the strongest industrially producible oxidizing agents, and is commonly used for the treatment of water in municipal and industrial applications. The special advantage of ozone is the environmentally-friendly way in which it works. Harmful substances, colors, odors, and microorganisms are destroyed directly by oxidation, without the formation of harmful, chlorinated by-products. Apart from the treatment of drinking water and wastewater, Xylem’s Wedeco ozone systems are used in bleaching processes, such as paper bleaching, as well as in other industrial oxidation processes.
Xylem’s Wedeco brand also offers Advanced Oxidation Process (AOP) solutions that are intended to eliminate a wide variety of toxic compounds and microscopic pollutants. Xylem’s Wedeco pre-engineered AOP systems are based on three key components – ozone, hydrogen peroxide, and UV light generated by low-pressure, high-intensity lamp technology. By combining these technologies, Xylem is able to meet customer’s individual requirements.
