Pulsed-Power Water Treatment as a Green Scale Inhibitor for HVAC and Once-Through Industrial Systems

摘要

This paper describes the use of a nonchemical (chemical-free) water treatment method, pulsed-power, to control scale formation under a variety of conditions. Nonchemical water treatment is the ultimate choice for environmentally responsible scaling inhibition, but most nonchemical methods have had a continuing problem with credibility regarding their efficacy. This paper describes cooling tower laboratory tests on a pulsed-power unit using the procedure from ASHRAE research project RP-1155. Case studies on a comfort-cooling cooling tower/chiller system and industrial once-through applications are also described. NACE publication 7K189, "Control Factors in Performance Testing of Nonchemical Water Treatment Devices" is used as a guideline.
