Demanding Robustness Ozone water treatment priorities When it comes to ozone water treatment systems, many operators understandably prioritise effectiveness but with uptime and long-term performance critical to plant success, its time to shine the spotlight on other factors. Here, Tim Puehmeier, Global Product Manager, WEDECO® Ozone Products at Xylem, discusses the importance of robustness when it comes to technology selection and meeting project efficiency objectives. For modern water treatment plants, fulfilling capabilities within strict budgets can be immensely challenging. The need for effective systems that operate with minimal costs and maintenance burden has never been higher. When it comes to treatment technology, reliability is therefore king. The ability to consistently meet performance and safety metrics with minimal servicing and oversight can provide extensive cost and energy savings over a system’s lifetime. And the quality that achieves this? Robustness. Ozone water treatment Ozone water treatment is a well-established process that has been around for more than 130 years. It offers a number of important strengths over other treatment types and simultaneously addresses multiple water quality issues through oxidation, disinfection, and decomposition. With no requirement for consumables, a short contact time, and environmentally safe operation, ozone water treatment is increasingly seen as an optimum solution. Today, state-of-the-art ozone systems have been designed to be incredibly robust. The ozone units require no conventional fusing and are virtually maintenance-free. It’s just the system’s associated instrumentation and supporting components that will require an annual instrument calibration, biannual filter replacement, and a destruct catalyst change every three to five years, depending on operation. Even the electrodes which sit at the heart of the systems, are now extremely robust and therefore reliable. PDOevoPLUS Ozone Systems SMOevoPLUS Ozone Systems PDOevoPLUS Ozone System

3G electrode technology An example of this is our ground-breaking Effizon® evo 3G electrode, which has been engineered for the demands of modern water treatment. From municipal wastewater facilities to industrial applications, it has been designed for robust and long-lasting performance and offers up to 11 per cent more energy-efficient ozone production. The carefully selected laboratory grade materials are corrosion resistant for longevity and the use of glass means there’s no risk of deformation of material over time or under physical stress. The core design is trusted and proven, having been...
