The on-site generation of disinfection chemicals is often safer than storing hazardous chemicals, and chlorine dioxide is one of the most popular, as it works across a broad range of pH and temperature levels, minimizing harmful disinfection byproducts. De Nora Water Technologies recently introduced Oxicore, a next-generation chlorine dioxide generator as the latest product line in its Capital Controls group of water treatment technologies.
According to De Nora, Oxicore delivers an up to 99% chlorine dioxide yield with precise dosing and on-demand production. Its scalable nature makes it flexible for a wide range of plant layouts, with a modular skid design that allows operators to expand capacity with minimal disruption, just by adding units. This feature also reduces the need for spare parts and minimizes installation costs. The fully-liquid, underwater system is designed for high efficiency and safety in mind. Its modular development enables flexible plant layout and easy upgrade or downgrade of capacity.
Safety features abound, as Oxicore operates without atmospheric tanks, includes onboard leak detection and fail-safe shutdowns, features continuous dilution to prevent gas accumulation, and is designed for safe and easy accessibility during maintenance.
Oxicore produces chlorine dioxide on demand using hydrochloric acid and sodium chlorite with a high-reaction yield in a submerged reactor. The system can inject chlorine dioxide directly into a pressurized pipe or water basin, and is especially well-suited for a wide range of applications including municipal utilities treating potable water, industrial users managing process water or cooling towers, and facilities requiring scalable, containerized disinfection systems.
Chlorine dioxide is a powerful and selective disinfectant. Unlike traditional chlorine, it doesn’t promote the formation of disinfection byproducts, making it ideal for pre-oxidation of surface water for drinking water applications. Chlorine dioxide oxidizes iron and manganese, is effective over a wide pH range, and does not react with ammonia. According to De Nora, it is used for Legionella control, membrane pretreatment and biofouling control, algae control, and treatment of ammonia-rich waters such as fish farming. De Nora offers a range of systems under vacuum or under water, which ensures the safe operation of the systems.
With growing demand for on-site generation, more sustainable treatment methods, and advanced safety protocols, Oxicore meets an urgent need for next-generation disinfection systems according to De Nora.
