This was a report produced by the testing company SGS.


A 50-liter water tank was filled with tap water. Water from the bottom of the tank was recirculated, with a HydroFLOW installed on the primary transfer line. The entire fixture was sanitized before adding Staphylococcus Aureus and E. Coli with a population of 1.2x 105 (120,000) to the water tank.

Water was circulated through the piping system with HydroFLOW for an hour. Sample water was then taken from the tank to test the bacteria count.


After one hour, the bacteria count was down to a minimal value of less than one per milliliter. This corresponds to at least a 99.99% reduction.
