Xylem's WEDECO brand has developed a new open-channel ultraviolet (UV) disinfection system that delivers clean, safe, treated wastewater of the highest standard using a minimum of energy. The WEDECO Duron UV system eliminates the need for chemical-based disinfection, as well as delivering lower operating and maintenance costs. Another key benefit is its small footprint.

5 Keys To Ozone Disinfection Success By Thoram Charanda, Chief Scientist, Guardian Research & Development Labs, and Louis LeBrun, PE, Vice President, Pinnacle Ozone Solutions, LLC
Ozone disinfection of water has been a common practice for nearly 100 years. Although there have been many improvements in ozone technology over the years, the basics principals hold the biggest keys towards the success of your installation. Provided here is a list of the five most important factors you should consider when embarking on any ozone disinfection project.
Monochloramine Monitoring: Reliable Analysis, Safer Drinking Water By Randy Turner, Technical Director, Swan Analytical USA
Chloramines are less aggressive disinfectants that react more slowly than chlorine, but they remain longer in the distribution system. Given more stringent disinfection byproduct (DBP) regulations, chloramination can be an appealing alternative to the use of free chlorine as a means of limiting DBP formation, particularly trihalomethanes (THMs). Chloramine is a general term that describes three related compounds, including monochloramine — the preferred chloramine compound for drinking water disinfection.
Rainwater For Reuse As Drinking Water By UV Pure Technologies
When McMaster University in Hamilton, Ontario, built their new Engineering Technology Building, they used the latest state-of-the-art technology not only to achieve LEED Gold certification, but also to create a living laboratory to train students on the building systems of the future.
Energy-Efficient And Low-Maintenance UV Solutions Have Favorable Impact By TrojanUV
Favorable reviews of UV technology in wastewater applications influenced Tianjin Economic Development Area (TEDA) Water Supply General Company to investigate the potential of using UV for drinking water applications at one of its water treatment plants. With no previous UV installations for drinking water disinfection in China, TEDA's process of selecting a UV manufacturer was stringent.
Reducing Emerging Contaminants In The Water Cycle By Advanced Oxidation Processes (AOP) By Ron Port, Xylem Inc.
Due to the development of analytical methods and instruments in the past few years, pollutants which had not been detectable in our drinking water sources have now become visible. They are anthropogenic and persistent substances in the water cycle, which conventional treatment methods are not able to remove. Efficient barriers, particularly for shortened recycle loops for potable water production, are needed.
Switching from gas chlorine to sodium hypochlorite is no panacea. Adding to the burden is the proposed U.S. EPA regulation for perchlorate. Considering the factors that lead to excessive perchlorate formation, switching to calcium hypochlorite provides utilities another key advantage.
MicroDynamics microwave-powered, open channel ultraviolet (UV) disinfection wastewater systems from Severn Trent Services meet dose, log reduction, and water quality requirements for a variety of applications. MicroDynamics systems use microwaves to energize low-pressure, high-output electrodeless lamps to generate UVC output at 254 nm.
With today’s steadily growing populations, water and wastewater facilities have a crucial role in every community. They must simultaneously protect the environment, keep waterborne diseases in check, and provide water suitable for industrial and human consumption. Furthermore, they must keep rates low, adapt and comply with changing regulations, and operate on a restricted budget.
