    Monitoring once through cooling water

    The Situation

    Power plants and paper mills use service water loops and mill water loops respectively for the cooling of lubricating, hydraulic, turbine and transformer oil.  These cooling systems feature large, recirculating volumes of water which are treated with biocides, dispersants, and corrosion inhibitors. By comparison, refineries often use once through cooling water systems. The cooling water is taken from lakes, rivers, or the ocean and circulated once through the plant to cool processes. Large volumes of water are used to keep the return water temperature low enough to prevent adverse effects on the environment.

  • HVAC and Cooling Filtration

    Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling cooling tower water, chilled water and heat exchangers, thereby reducing your cooling system efficiency.

  • Cooling Towers and Process Water System Cleaning Applications Using Hydrogen Peroxide

    The unique properties of hydrogen peroxide (H2O2) make it a good technology for keeping cooling loops, process water loops and heat exchangers clean from fouling that can occur due to various contaminants in the water. Hydrogen peroxide works well in removing organic fouling on surfaces through mechanical means and in specific applications through biocidal mechanisms. Hydrogen peroxide can be used in a shock treatment mode where it is fed based on a timer set-up. It can also be used occasionally at higher concentrations for maintenance cleaning purposes of fouled heat exchangers, cooling water loops and process water loops. Performing an occasional shock cleaning of a heat exchanger with hydrogen peroxide can remove buildup from surfaces and can result in improved heat transfer efficiency. By removing surface fouling, hydrogen peroxide may also improve the efficiency of other biocides such as bleach, bromine and non-oxidizers.

  • Water Disinfection for Industrial Water Treatment

    MIOX’s patented Mixed Oxidant Solution (MOS) or Hypochlorite (HYPO)chemistries for cooling tower and cooling loop water disinfection improves safety, lowers general corrosion rates, increases performance, and saves money. The unique qualities of MOS lowers corrosion rates by 80% in copper and 50% in steel, resulting in a reduction of downtime, maintenance, and expense. Additionally, MIOX generators improve workplace safety by eliminating the handling and storage of hazardous chemicals while maintaining steady disinfection residuals.

    Chlorine Dioxide Water Treatment for Power Plants

    Chlorine dioxide is a significant product in the control of algae, planktonic and sessile bacteria, bio-film and scale in power plants, cooling towers, loops and cooling systems. CleanOxide helps maintain the efficiency of heat exchanger surfaces, reservoir intakes and ancillary equipment. Traditional oxidising agents such as chlorine and bromine, on the other hand, are associated with pH constraints and corrosion problems.
