  • The cheapest, simplest, (yet highly effective) solution to cooling tower drift

    The problems caused by water drift are numerous. The water usually contains treatment chemicals that are corrosive and damage paint on nearby equipment, buildings, automobiles, etc. In cold climates, the drift can cause dangerous icing on the roads and walkways. In some cases, the drift represents a significant loss of water, treatment chemicals or process heat. If nothing else, drift is nearly ...

  • ACTIFLO® Clarifiers are Heart of Antioch, CA Recycled Water Facility

    Due to a number of economic and ecological factors, the California State Water Resources Control Board requires power plant developers to evaluate the use of recycle water for cooling tower needs. For this reason, Calpine (a power plant developer) formed a public-private partnership between itself, Bechtel Enterprises and the Delta Diablo Sanitation District (DDSD) to build a new recycled water ...

  • 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: ...

  • Bypass filtration in open circulating cooling water systems

    An open circulating cooling system is a method to remove process heat and is applied frequently for industrial purposes. In these systems heat is removed by evaporation of water to the surpassing air in the cooling tower. However there are some environmental disadvantages such as addition of chemicals to prevent the cooling water system from microbial growth and corrosion. The application of ...

  • Enumeration of Legionella pneumophila in cooling tower water systems

    Legionella pneumophila, the causative agent of Legionnaires disease, is known to colonise and frequently grow in cooling tower waters. Disease is acquired by inhaling aerosol contaminated by legionellae. Determination of the count of Legionella pneumophila in cooling tower waters may, therefore, be useful for risk assessment. In our survey, 103 water samples from 50 cooling towers were examined ...
