Process Description 

Based on over twenty-five years of experience, the HydroFLOW™ water conditioner provides an eco-friendly solution for the protection of any process water system from the harmful effects of limescale, bacteria, algae and bio-fouling.

Installed on the exterior of any piping system or pipe material, the HydroFLOW™ device employs a ferrite ring to apply an oscillating 150 kHz frequency that penetrates the pipe wall and travels both upstream and downstream from the point of installation.  The water within the piping system, acts as a conduit to propagate the signal throughout the system, conditioning the water, whether it is moving or stationary.  Testing has proven that the Hydropath signal is more efficient and effective than similar water conditioning technologies.

The water solution typically contains minerals, such as calcium carbonate, dissolved in the form of ions.  Evaporation concentrates the dissolved minerals.  When the temperature of the solution increases, or its pressure drops, the solution becomes supersaturated which causes the dissolved ions to precipitate out of solution, adhering to piping and equipment surfaces in the form of scale. 

The HydroFLOW™ signal induces the dissolved minerals to cluster and precipitate as stable crystals that remain in suspension and do not adhere to piping and equipment surfaces.  Likewise, the signal disrupts the growth of bacteria and algae, causing them to perish; biofilm colonies detach from pipe and equipment surfaces.  The suspended particles, either mineral or biological, are filtered or flushed out with the process blowdown.

Benefits

    1. Elimination of scale and biofouling without chemicals:  The oscillating 150 kHz signal induces dissolved minerals to cluster and precipitate in solution, instead of on to equipment surfaces, such as tubesheets, heat exchanger tubes, and tower fill.
    2. Increased energy efficiency, due to elimination of insulating scale and bio-fouling adhering to heat transfer surfaces.  Energy savings ranging from 5% - 10% are achievable.
    3. Improved corrosion protection:  Operation of circulating water at higher pH promotes magnetite formation on carbon steel surfaces and protects against pitting/crevice corrosion.
    4. Remineralization / softening of existing scale, resulting in reduced maintenance costs for pipeline, heat exchanger tubes, and tower cleanings.  The HydroFLOW™ technology softens existing scale, facilitating removal without damage to equipment from harsh chemicals or abrasive cleaners.  Left alone, scale will dissolve or be removed by agitation from turbulent flow.
    5. Elimination of acid dosing for pH adjustment:  HydroFLOW™ operates without the need for acid dosing to adjust pH for scale control.  Your site and building will be safer with the elimination of operator exposure to hazardous, concentrated sulfuric or hydrochloric acids.
    6. Asset protection:  Operation of the cooling tower circulating water at pH above 9.0, reduces the risk of corrosion to equipment, such as condensers, heat exchangers, and pipelines, protecting expensive equipment from premature failure and unexpected outages.  Future capital expenditures are often deferred, improving return on investment and conserving capital.
