  • Cooling Tower Blowdown Water

    Comparison of electrolytic oxidation v. ozone as biocide and reducing rate of TDS build-up in Cooling Tower Blow Down Water. Performed by Pureflow PtY Ltd of Singapore at Singapore Polytechnic Institute. Open evaporative cooling systems have been widely used throughout industry to remove heat from process systems and modern buildings for the purpose of air conditioning. As a result, due to this ...


  • Cooling Tower Drift Elimination

    ABSTRACTIn certain cases cooling tower drift (mist) can overwhelm conventional lower efficiency chevron mist eliminators.  This paper explores an alternative strategy to control drift in those cases.  The author uses a case history to illustrate conditions that can be expected to cause uncontrolled drift and to discuss a solution.  The author acknowledges that the information presented is ...

  • 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 ...

  • Ozone treatment for cooling towers

    Abstract The use of ozone as a maintenance treatment for cooling towers has good potential for operation and maintenance savings in the Federal secior. A small amount of ozone acts as a powerful biocide thai decreases or nearly eliminates the need to remove quantities of water from the cooling tower in order to decrease the concentration of organic and mineral solids in the system. ...

  • The Use of Ozone in Cooling Towers

    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 reducedon-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 benefits which ...

  • 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: ...

  • HydroFLOW and Cooling Tower eliminating the need for chemical treatments case study

    Misericordia Hospital – Alberta – 2011 In June, 2011 Misericordia Hospital began a three-month trial on two of the three cooling towers in its facility. The test compared the effectiveness of HydroFLOW in eliminating limescale and algae vs. standard chemical treatment. Standard chemical treatment was removed from Cooling Tower #3 and a P-160 HydroFLOW unit installed. Standard ...

  • DOCUPAK LLC REDUCES COOLING TOWER CHEMICAL USAGE BY A THIRD

    Docupak LLC, a full service marketing company headquartered in Alabaster, Alabama, has reduced chemical usage by a third and removed all scale from its cooling tower at its plant after installing the patented, award-winning Scalewatcher computerized, electronic water-conditioner from Scalewatcher North America.   In addition ...

  • Ozone cooling tower treatment with and without mineral removal

    Abstract This paper builds on a prior paper by this author, McGrane (1991), In that paper, ozone is used as the sole means of cooling tower water treatment. The paper discusses water conservation by increased cycles of concentration, greatly increased efficiency through extremely low biological populations, and corrosion data which is compared to ozonated and chemically treated towers. ...

  • 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 ...

  • Chiller & cooling tower water treatment - case study

    Overview There are three main challenges for treating cooling water in both open and closed loops: scale, corrosion and biogrowth. Water System Challenges The traditional chemical treatment calls for chemicals to deal with these challenges. When scale is present, the condenser’s ability to transfer heat is reduced, causing higher pressure and higher ...
