Cooling Water Contamination Applications

Industrial solutions for cooling water contamination

Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

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.

Instrumentation technologies for industrial

There are many industrial operations that are producing waste water and process water that is at risk of contamination with e.g. lubricating oils or cooling oils. There is also significant use of cooling water at risk of contamination through leaks in heat exchangers and condensers.

Instrumentation technologies for refineries

The petroleum refining industry uses a wide range of processes, from separation, petroleum conversion, and petroleum treatment to waste water management. Each of these processes has its own challenges and all are made more complex by the variety of products and contaminants in the process. Two key areas, from the water management perspective, are cooling water and waste water treatment.
