HSD Water, offers OXAQUA RW; a reliable and sustainable water disinfection technology.
Based on the water electrolysis principle, OXAQUA RW sanitizes water stored in tanks and water towers by recirculating continuously a flow rate up to 7 m³/h without any addition of chemicals nor precursors such as sodium chloride. In addition it creates a small residual of oxidizer up to retain the quality of water while in storage or until the end-user’s point of use.
OXAQUA RW creates a recirculation loop of the (drinking) water storage tanks using an integrated pump. Its electrode will activate only when the oxidizer residual is reaching a low level (Built-in chlorine analyser provided in option OXAQUA RW CL).
OXAQUA RW uses the chlorides naturally present in the water to be treated (concentration has to be above 20 ppm Cl-) to generate on site and on demand up to 2 ppm of free chlorine under the form of hypochlorous acid, a strong oxidizer known for the prevention of the proliferation of bacteria, viruses, algae and molds in drinking and hot water systems. It is also efficient against many pathogens, such as E. Coli or Legionella Pneumophila.
Key applications of the system are:
