09-05: Chemical Free Bacteria & Legionella Control: A Case Study Using Fans & Associated EquipmentThis paper describes an alternative, patented, non chemical cooling water treatment system that has proven to be effective in controlling eradicating bacteria and Legionella. The technology works primarily on the principals of Controlled Hydrodynamic Cavitation (CHC). The VRTX system eradicates bacteria by a combination of four synergistic actions: pressure, vacuum, kinetic impact and sheer force at the collision point. Within the chamber the
