The removal of waterborne pathogens in stormwater runoff is an increasing global priority. In response, A S Filtration™ has developed a proprietary antimicrobial integrated system proven to destroy pathogens on contact. Pathex™ provides effective high flow treatment at the nano-level against harmful bacteria including E. coli, enterococcus, and fecal coliform.

Pathex™ physically ruptures microorganisms on contact which does not allow for adaption or reproduction. This innovative technology allows non-viable microbes to flow through the filter media at relatively high loading rates of stormwater runoff. Treatment does not use traditional methods of trapping, chemicals or heavy metals. Pathex™ is non-toxic, not consumed, and leaves no environmental residue.

Treatment does not rely on physical trapping; thus, the dead microorganisms can pass through the Pathex™ filter medium without clogging. The antimicrobial agent is not consumed, does not dissipate, and does not produce toxic metabolites. Pathex™ is safe to handle and leaves no environmental residue. Microorganisms are completely destroyed on contact which does not allow for mutations to later develop on the medium.

Pathex™ filter medium has demonstrated superior performance for the elimination of E. coli and enterococci in a variety of test conditions; and, provides effective treatment which can be achieved over an extended period of time. The use of a known EPA-registered antimicrobial agent with Pathex™ filter medium can also be applied to safely remove a wide spectrum of pathogenic microorganisms such as Cryptosporidium, Legionella, Salmonella, Staphylococcus, Streptococcus, etc. It is clear that the A S Filtration™ Pathex™ technology can provide for the highly effective, long term, and safe control of waterborne pathogens to a wide variety of applications.
