A S Filtration Registers Filter Media With EPA As Antimicrobial Pesticide

Tuesday, June 3, 2014

Pathex, an antimicrobial filter media manufactured by A S Filtration, LLC, has been registered by the U.S. Environmental Protection Agency as an “antimicrobial pesticide.”   

“This innovative product has been recognized as effective in the reduction and control of waterborne coliform bacteria in multiple applications,” states J. Kelly Williamson, president of A S Filtration. 

With only about 2.5 percent of the world’s water available for human consumption, keeping usable water clean is a global priority. Economic growth and population pressures place demand on all types of water whether it is industrial process water, stormwater or drinking water. Effective media for new and old filtration systems is needed, and Pathex is proving to be a key asset in managing environmental challenges while improving energy and water savings for customers using the product, said officials. 

Traditional water treatment technology includes liquid biocide chemicals like chlorine, bromine, ozone and other oxidizing agents, ultraviolet lighting or reverse osmosis which often produce toxic disinfection byproducts, corrode downstream equipment and can increase energy needs, water use and maintenance costs. 

Pathex is recognized as the only water filter media registered with EPA as a pesticide and classified as a new use of an active ingredient, while also holding certification to NSF/ANSI Standard 61 for drinking water system components. Pathex is stable, non-toxic, non-leaching, non-corrosive, not consumed with use, requires no power source for efficacy and is not affected by temperature changes. 

“Pathex has attracted significant interest for managing stormwater effluent, as well as industrial applications like recirculating cooling towers, heat transfer systems, service water and auxiliary systems and municipal wastewater treatment.” Williamson said. “We have also received inquiries from companies in the health care and hospitality industries.” 

Pathex’s antimicrobial efficiency is achieved at high loading rates up to 20 gpm/square foot. Pathex kills coliform bacteria as the organisms physically move over the hostile surface of filter media granules while avoiding the formation of destructive disinfection byproducts.
