  • Mixed-oxidant application in cooling tower maintenance

    Tests using the MIOX-generated mixed-oxidant solution instead of oxidizing biocides (chlorine or bromine) for cooling tower maintenance, and eliminating all other biocides, in first an established cooling tower and subsequently in two new cooling towers found: (1) aerobic bacteria counts consistently less than 1000/mL in the cooling water (no colonies on the standard Easicult TTC1 dip slide ...

  • RYDLYME improves efficiency on cooling tower case study

    A 35-ton cooling tower at a major college had compressors operating at more than 260psi just to maintain a 70°F water temperature due to heavy water scale. RYDLYME was put into the system to dissolve the scaling. RYDLYME approach 55 gallons circulated for 4 hours via inline pumps and then flushed with water. Cleaning was done while system was in ...

  • Maintenance tips for cooling towers - White Paper

    Cooling towers are prone to the typical causes of rotating machine failure such as misalignment, but also face a range of specific environmental challenges, including high or gusting wind speeds, dust, sand and, in coastal locations, high concentrations of salt. In the 1990s, for example, vibration and accelerated wear caused a fan blade to shear off a cooling tower in Pennsylvania, ...

  • New York Legionella regulations: are they missing the boat?

    Abstract A large outbreak of Legionnaires’ disease in the Bronx in 2015 prompted NYC to enact law and NYS to propose emergency regulations on the registration and maintenance of cooling towers. This paper describes the fundamental characteristics of point sourced vs. potable water sourced outbreaks and discusses the Bronx outbreak from those perspectives. Ultimately a case is made that ...

  • 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. ...

  • Upgrade Fill Media to Improve Cooling Tower Efficiency

    One of the simplest and most cost-effective ways in which to extend the life of a cooling tower, improve heat transfer efficiency and reduce maintenance downtime, is to upgrade the cooling tower’s fill media to components constructed out of robust and non-clogging materials such as Polypropylene (PP), PVC or stainless steel. Fill is a critical component in the heat transfer ...

  • Looking Beyond Chemical Water Treatment Case Study

    When you think of an environmentally friendly company, a steel processing plant does not typically come to mind. However, Stripco Inc. of Mishawaka, IN, a manufacturer of production-ready, cold-rolled steel coils, is the exception. In August of 1995, Stripco made a wise decision that also proved to be cost-effective and environmentally- friendly when they installed a Superior Environmentalist ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...
