  • 1.  Cooling Towers for Hot Groundwater

    Posted 04-03-2019 02:24 PM
    Howdy y'all,

    I'm trying to locate any sort of guidance there might be about using cooling towers in water distribution to cool hot groundwater (~150*F) before sending it out to distribution. Any resources would be much appreciated.

    Contact someone like Sargent & Lundy in Chicago, Illinois, or even American Electric Power (AEP) in Columbus, Ohio.  The utilities have been using cooling towers for decades. They are simple and effective.

    Consider placing a heat-to-electricity engine between your hot ground water and the cooling.  As a good first check, talk to ElectraTherm: https://electratherm.com/.  There are now several manufacturers of what are normally considered "geothermal" electrical power units that "work" with relatively low-grade heat.  I last considered ElectraTherm units using the "waste" heat from diesel generator engine jackets (185F) at least 5 years ago.  I believe they can include the cool-water side equipment in their installation.  Cool water side can be: radiator-to-air cooled; evaporative cooling tower; water heat exchanger (whatever salinity).  A cool cool-side is as important as a hot hot-side for the economics.

    Thank you for your responses, James and Mark! That should send me in the right direction.  I'm excited to hear that there might be a use for the waste heat-- everyone else I had previously spoken with said the water wasn't going to be hot enough to have any potential uses.
