During the evaluation process, stringent testing verified that PathShield antimicrobial filter media destroys coliform bacteria on contact and is non-toxic, making it an effective solution for reducing and controlling bacteria in stormwater, industrial wastewater, and municipal wastewater.
AS Filtration developed PathShield as a unique stable, non-toxic, non-leaching, non-corrosive product to kill and control waterborne coliform bacteria, virtually eliminating the harmful consequences of conventional oxidizing biocide treatment methods.
Typical water filtration solutions require multiple stages to be effective to remove solids, like sediment and debris, then chemical treatment to address harmful waterborne bacteria. Water treatment products, like oxidizing biocides, can themselves be harmful to the environment. PathShield, however, filters and treats the water in a single step, without using or releasing toxic chemicals or destructive disinfection byproducts.
PathShield does more than physically remove debris and bacteria; it kills coliform bacteria that pass through the media. This biocidal action is continuous at high flow rates, with a surface area loading rate up to 20 gallons per minute per square foot. PathShield’s silica granules are considered a drop-in replacement for standard sand filter media, making it an economical solution for stormwater and most wastewater treatment applications.
California has long been recognized as the leader for establishing stringent environmental and consumer protection standards. Achieving both CDPR and U.S.EPA registration is an undeniable testimony that PathShield is an effective and innovative water treatment solution for filtration and bacterial control that can increase the beneficial uses of our water resources.
