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 particle, either mineral or biological, are filtered or flushed out with the process blowdown.


    1. Elimination of scale without chemicals:  The oscillating 150 kHz signal induces dissolved minerals to cluster and precipitate in solution, instead of on to equipment surfaces, such as boiler tubes and drums.
    2. Reduced water and chemical consumption:  The HydroFLOW™ technology controls scale allowing higher cycles of concentration minimizing the cost of expensive treatment programs.  Higher cycles results in lower blowdown and less make-up, conserving water, chemicals, and dollars.
    3. Increased energy efficiency:  Elimination of insulating scale adhering to heat transfer surfaces allows for energy savings ranging from 5% - 10%.
    4. Improved corrosion and asset protection:  For boilers that operate with softened water, HydroFLOW™ technology reduces carbon dioxide (CO2) carryover into condensate return piping, providing two benefits:
      1. Immediate reduction in the need and savings for neutralizing and filming amines to protect equipment from carbonic acid corrosion
      2. Risk reduction from premature failure and unexpected outages due to lower corrosion potential.  Future capital expenditures are often deferred, improving return on investment and conserving capital.
    5. Remineralization / softening of existing scale, resulting in reduced maintenance costs for pipeline and heat exchanger tubes.  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.
