Reduces Biological Growth in Cooling Towers "Significantly Better" Than Previously Tested Non-Chemical Solutions

In a controlled test by Radisav D. Vidic, Ph.D. and Janet E. Stout, Ph.D., of the University of Pittsburgh, Silver Bullet Water Treatment LLC’s system was found to perform “significantly better” than previously tested non-chemical solutions in controlling free-floating and immobile growth of HPC bacteria in a pilot-scale cooling tower.

The findings demonstrate that the system from Silver Bullet dramatically reduced total bacterial counts (HPC bacteria) in pilot-scale cooling towers. The controlled study was conducted by the Department of Civil and Environmental Engineering at the University of Pittsburgh and directed by Drs. Vidic and Stout. Previous studies by the University of Pittsburgh group funded by the American Society of Heating, Refrigerating and Air-conditioning Engineers (ASHRAE) showed that five other non-chemical water treatment devices could not similarly reduce bacterial growth in the towers.

Silver Bullet’s executive chairman, Robert Hanfling, said, “Our goal is to save customers water and energy, and reduce their operating costs – while eliminating the use of toxic chemicals. The University of Pittsburgh’s independent study confirms that our system reduces both HPC and Legionella bacteria in cooling tower bulk water.”

According to Dr. Vidic, test results showed that the Silver Bullet device reduced the average free-floating HPC bacteria concentration by 98.8%, and met generally accepted industrial biofouling control recommendation for free-floating bacteria. The test done in a model cooling tower system that simulates realistic field conditions also showed that Silver Bullet’s technology reduced concentrations of biofilm HPC bacteria by 85.9%, and free-floating Legionella bacteria by 78.1%.

“These findings validate the cost-and environmental-effectiveness of our commercial water treatment product, which replaces toxic chemicals in treating water in cooling towers and agricultural drinking water systems,” Hanfling said.

Silver Bullet’s cooling tower treatment product is currently installed in buildings throughout the United States; including hospitals, hotels, data centers and office buildings. Its agricultural product is treating animal drinking water on large farms in Colorado and Kansas. The company is based in Denver, Colorado.
