Abstract

This paper describes an alternative, patented, non-chemical cooling water treatment system that has proven to be effective in controlling/eradicating bacteria and Legionella. The VRTX system is a side-stream treatment system and includes a mechanical VRTX unit and a separation/filtration unit. The VRTX unit works primarily on the principals of Controlled Hydrodynamic Cavitation (CHC). The CHC actions destroy microbial cell walls and converts dissolved calcium and bicarbonate ions into aragonite calcium carbonate (CaCO3) colloids, when cooling water is pumped through the VRTX unit. The separation unit is used to remove the precipitated calcium carbonate and other suspended solids from the recirculating cooling water to keep the cooling water system clean.

The VRTX system eradicates bacteria by a combination of synergistic actions: pressure, vacuum, kinetic impact and shear force at the collision point, hydrodynamic cavitation, sonic waves and oxidizing chemicals produced from cavitation. In this paper, laboratory and field tests results are presented to demonstrate the effectiveness of VRTX system in controlling bacteria and Legionella in cooling water systems.
