De Nora at your service


Capital Control Gas Feed Systems & Chlorine Dioxide Generators



Chlorine dioxide is an ideal solution for membrane pre-treatment, biofouling and algae control. As an iron and manganese oxidant, chlorine dioxide is effective over a wide range of pH levels and does not react with ammonia or form TTHM or HAA disinfection byproducts.


With hundreds of chlorine dioxide generator installations worldwide, De Nora leverages generations of technical expertise to develop the industry standard in chlorine dioxide disinfection—a modern, flexible, and safe line of chlorine dioxide generators.
Now you can optimize your Capital Controls® Chlorine Dioxide Generator with various kits designed to promote efficiency and safety while lowering OPEX.
