Pilot study

    Cooling tower deposition study

    Treated vs. untreated specimen behavior under stressed cooling tower conditions. This study examines deposit characteristics and ease of removal.

    03 / Key findings

    Observations

    Deposits behaved differently on the two tubes under stressed conditions. Water top-ups were not measured consistently, so water savings need a separate measurement at your site.

    1. Different deposition behavior observed between specimens
    2. Treated deposits showed softer consistency
    3. Easier removal from treated specimen surfaces
    4. Additional site-specific testing recommended

    A trial in your cooling tower

    Agree on measures for deposit behavior and cleaning needs. Measure any water or energy changes separately.
