Stay compliant and slash your energy costs by 30% with Ecoray Upgrade Kits.

Long and trouble-free performance — Ecoray lamps come with a 14,000 hours operating warranty when used together with Ecoray ballasts, plus 9,000 hours full replacement.

Ozone is one of the most powerful commercially available oxidants and is commonly used for municipal water and wastewater treatment. In addition to its oxidizing capabilities, it is an environmentally-friendly method of treatment.

WEDECO LBX e UV system is a compact closed vessel UV reactor for drinking water, wastewater, water reuse, and WEDEO’s MiPRO Advanced Oxidation Processes (AOP) applications. Equipped with WEDECO’s low-pressure, high output amalgam ECORAY® UV lamps and OptiDose sensor based control, the LBXe provides the highest operating efficiency with low life-cycle costs. Additionally, the LBXe reactor’s extensive validation envelope ensures disinfection performance over a range of UV transmittance (UVT) values, flowrates, and a variety of target organisms.

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.

  • This presentation will look at the role that Ozone treatment plays addressing the evolving challenges of the water resources here in North America. During the presentation, we will review how ozone treatment is being used to address various drinking water challenges ranging from taste and odor to the contaminants of emerging concern.  We will also discuss the role that ozone plays in water reuse applications, providing multiple benefits in the reuse treatment train. Please join us as provide an overview of Ozone as a tool in meeting the complex challenges of today’s water and wastewater treatment requirements.

  • Ralph Franco, PE, Applications Engineering Manager North America for WEDECO -- A Xylem Brand discusses the treatment and future regulation of 1,4-dioxane at the Water Online Virtual Water Expo.

  • Contaminants of emerging concern (CECs) can be a challenge throughout all stages of the water cycle. Here are some key considerations for water treatment plants (WTPs), wastewater treatment plants (WWTPs), and water reuse applications where removal of 1,4-dioxane or per- and polyfluoroalkyl substances (PFAS) is currently, or might soon become, a mandatory focus in their treatment train.

  • In the constant flow of drinking water and wastewater treatment systems, operators have precious little time to skip a beat. When unexpected changes arise — such as being mandated to reduce contaminants of emerging concern (CECs) — the ability to maintain balance throughout the treatment process becomes a driving factor. For decision-makers faced with remaining resilient despite CEC concerns, here are some key points to consider.

  • Water treatment challenges are never-ending — from source water availability, to seasonal upsets, to new contaminants of emerging concern (CECs). The best way to stay ahead of such issues is to cultivate a pipeline of innovative solution development ready to address the next challenge. Here are some key insights for evaluating suppliers that are best positioned to do exactly that.

  • As a utility, it is tough enough to be notified that you need to remove a new contaminant of emerging concern (CEC). It’s even harder without having a complete picture of what is involved. For water treatment plants (WTPs) and wastewater treatment plants (WWTPs), here is how choosing the right testing regimen is essential to quantifying the degree of the problem and evaluating the optimum treatment alternatives.

  • Advanced oxidation treatment system and water treatment plant upgrade save money.

  • Small city selects full-featured and low maintenance UV treatment for its water reuse system that easily complies with demanding California Title 22 Regulations.


Using processes that are both future-oriented and ecologically friendly, the products from WEDECO -- A Xylem Brand are committed to improving the foundations on which we live, on a global scale. The broad outline of our business is to realize the best possible solution for mankind and the environment, and the most economic solution for our clients.

Ecological policies and economic success

Life cannot be sustained without water. Water is our most valuable resource. Mankind needs increasing amounts of clean and healthy water worldwide.

  • Only 1% of the earth’s water is fit for human use
  • Over 250 billion gallons of water are used each day
  • Water consumption doubles every 15 years
  • One sixth of the world’s population suffers from a chronic shortage of water
  • 11 million people become ill every day due to contaminated water
  • 25 million people die each year from water-based illnesses


180 billion US$ are needed to give all the people of the world access to clean and healthy water by 2025. WEDECO products are meeting the challenge of the 21st century. With UV disinfection and Ozone oxidation, we have the advanced technologies for chemical-free and environmentally friendly treatment of drinking water, wastewater and process water.


Our high-tech water treatment systems ensure that:

  • water can be recycled
  • water for human use does not cause illness
  • water treatment does not impose a burden on the environment


High Tech for healthy water and a better environment

WEDECO products have been installed in over 250,000 systems worldwide and have over 30 years of experience in technical expertise in the field of ultraviolet and ozone technology. Committed, highly qualified experts in the research & development, production, sales, commercial and technical operations and customer service departments all contribute to the company's success.

Interdisciplinary research groups made up of electrical engineers, process engineers, microbiologists, doctors and physicists, both internal and external, work to continuously develop and optimize WEDECO UV and Ozone systems.

Apart from our work within the company, we also team up with international institutes to work on current research projects. We concentrate on sewage recycling, focusing especially on eliminating pathogens such as cryptosporidium and amoeba. In the USA, we are working on a project that involves introducing purified and sterilized sewage directly into the ground water and in so doing, we aim to raise the ground water from its current low level.
