Xylem's New Energy Efficient Closed-Vessel UV System For Wastewater Disinfection And Reuse Unveiled At WEFTEC
Xylem Inc., a leading global water technology company focused on addressing the world’s most challenging water issues, has further extended its capacity range of closed-vessel, ultraviolet (UV) disinfection solutions for wastewater, industrial and water reuse applications with the launch of the WEDECO LBXe 850 and 1500. Optimized for large-scale applications, Xylem’s WEDECO LBX series is highly energy-efficient and has been fully validated according to the US Environmental Protection Agency’s UV Disinfection Guidance Manual (USEPA’s UVDGM 2006). It has also been validated according to the National Water Research Institute (NWRI) 2012 guidelines by independent, industry-leading Carollo Engineers.
The new LBXe 850 and 1500 models strengthen Xylem’s portfolio in the higher flow rate ranges and meet an increasing demand for UV solutions for large-scale water reuse projects. Capable of handling peak flow rates up to 2120 m³/h (8.5 MGD) per reactor the LBX 1500 will be one of the largest validated closed-vessel, low-pressure lamp wastewater systems in the industry. Both new LBXe units feature an ‘OptiCone flow diverter’ which channels the flow evenly across the lamps to maximize disinfection efficiency and come in the “L” configuration for easier installation. Both models will be unveiled at the Water Environment Federation Technical Exhibition and Conference (WEFTEC) 2013 (Xylem booth #1443) in Chicago, Illinois October 7th – 9th.
While validation is the norm for drinking water treatment systems it is not as common for wastewater solutions. Xylem’s WEDECO brand is a pioneer in this area, having launched the first UVDGM compliant vessels for wastewater applications in 2010. In addition, the WEDECO LBX Series was the first closed-vessel, low pressure, high output amalgam UV system in the world to obtain the stringent California Title 22 acceptance. With its WEDECO LBX series Xylem is providing customers with a solution that will support them to meet future regulatory requirements.
Dr. Bertrand Dussert, Global UV Business Manager at Xylem said, “As climate change, water scarcity and growing environmental awareness drive stricter effluent standards and water reuse initiatives, validated UV systems are fast becoming an essential component of wastewater treatment plants. Whenever a pressurized system is beneficial for the customer the LBX series is the ideal solution.”
UV treatment is an environmentally sustainable solution and a very effective alternative to chemical-based disinfection such as chlorine treatment. As a chemical-free treatment, UV disinfection does not carry the risk of forming harmful by-products, such as trihalomethanes (THMs) and haloacetic acids (HAAs).
WEDECO’s low-pressure, high-output amalgam UV systems offer superior performance due to the highly efficient ECORAY lamp technology. Designed by the Xylem WEDECO team ECORAY lamps consume approximately one-third of the amount of energy that medium pressure lamp systems need to operate. Compared to other low-pressure, high-output amalgam UV lamps, they provide the benefit of longer lamp life, higher sustainability, superior dimming capabilities and lower mercury content. WEDECO’s extensive experience with ‘sensor-based dose pacing’ offers additional energy savings. The OptiDose Control ensures the required dosage is applied while conserving power and lamp life. Additionally the automatic wiping system maintains maximum sleeve transmittance resulting in peak efficiency. By keeping the sleeves continuously clean, the system uses less energy and lowers operational costs and maintenance effort.
Xylem’s WEDECO LBX series successfully treats a wide range of liquids in many different industries and has been installed in more than 1,000 traditional and specialty treatment plants worldwide. It is a very adaptable and flexible system that can be tailored for wastewater treatment plants and industrial applications, such as disinfection of sugar syrup within the food and beverage industry. Moreover, it is an attractive solution for water treatment plants using surface water as source.
Xylem is a leading global water technology provider, enabling customers to transport, treat, test and efficiently use water in public utility, residential and commercial building services, industrial and agricultural settings. The company does business in more than 150 countries through a number of market-leading product brands, and its people bring broad applications expertise with a strong focus on finding local solutions to the world’s most challenging water and wastewater problems. Xylem is headquartered in White Plains, N.Y., with 2012 annual revenues of $3.8B and approximately 12,900 employees worldwide. Xylem has been named to the Dow Jones Sustainability World Index for the last two years for advancing sustainable business practices and solutions worldwide.
The name Xylem is derived from classical Greek and is the tissue that transports water in plants, highlighting the engineering efficiency of our water-centric business by linking it with the best water transportation of all -- that which occurs in nature.
