  • Cooling tower case study

    Cooling towers have always been difficult to control. Algae grow in the cooling tower itself and on the grids used. In addition to micro-organisms and biofilm, they reduce the efficiency of the cooling tower. Furthermore the risk of spreading Legionella is a serous factor to be reckoned with. Many of the traditional methods to fight algae are either insufficient, cumbersome, environmentally ...

  • How to Save with Cooling Tower Credits

    Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper ...

  • The Control of pH and Oxidation Reduction Potential (ORP) in Cooling Tower Applications

    The importance of keeping cooling tower water in proper chemical balance is becoming clearer. Cooling tower treatment control systems can limit scale formation to improve efficiency, limit corrosion to increase the service life of the cooling water system, and maintain a residual halogen level to reduce liability associated with biological growth, particularly Legionellae.   The use of ...

  • Biological Control in Cooling Towers Treated with Pulsed-Power Systems

    Biological control is the foundation of cooling tower water treatment. Biofilm can directly cause corrosion problems (microbial induced corrosion, MIC), pathogen concerns (Legionella), increased pump pressure, heat-transfer problems, dermatological effects, and malodors. With the increasing restrictions being imposed at the federal and state level regarding chemical use in cooling towers (CAA, ...

  • Cooling tower legionella pneumophila study CDC

    Abstract Since the late 1970s, there have been many small and large outbreaks of Legionnaires’ disease. Most of these outbreaks have been traced to either cooling tower water systems or potable water systems. Although the bacteria most often associated with Legionnair’s disease, Legionella pneumophila, is present in many waater systems, outbreaks are usually a result of ...

  • Neosens™ on-line Fouling monitoring for Cooling Towers

    A New Approach to Fouling Control Neosens offers innovative, cost effective sensor solutions for monitoring the presence of biofilm and scale in cooling towers, heat exchangers and other industrial process applications. Fouling in cooling systems is a worldwide, multi-billion dollar problem, reducing energy efficiency, increasing maintenance costs and creating health risks due to ...


  • Economical calculations for the use of Ozone in Cooling Towers

    Abstract Ozone has been successfully applied to industrial cooling water systems with the resultant improvement in operational efficiency due to increased heat transfer, reduced system corrosion, improved environmental impact and reduced on-going chemical expenditure. The aim of this paper is to provide practical advice on the options available for the application of ozone and the potential ...

  • Cooling tower for Chemical processing plant - case study

    This chemical processing plant needed clean, debris-free water for cooling purposes. We created custom traveling water screens for their cooling tower that are compact and efficient. Smaller mesh sizes can catch fine debris for a this type of installation. No matter what architectural or engineering constraints, we’ll create a water screen solution that fits. This project included: ...

  • Use of cooling tower blow down in ethanol fermentation

    Reducing water consumption in bioethanol production conserves an increasingly scarce natural resource, lowers production costs, and minimizes effluent management issues. The suitability of cooling tower blow down water for reuse in fermentation was investigated as a means to lower water consumption. Extensive chemical characterization of the blow down water revealed low concentrations of toxic ...

  • An alternative cooling tower disinfectant: On-site generated mixed oxidants

    Favorable temperatures (80-110°F) and availability of nutrients make cooling tower systems ideal places for microbial growth. Accumulation of biofilm impedes proper heat transfer and secretes metabolic products that contribute to microbiologically influenced corrosion (MIC). The films also may propagate and release disease-causing bacteria. Control of microbial growth is traditionally ...
