In 2013– Purifics installed and set to work a one million gal/day Photo-Cat Water Purification System in Mississippi to destroy 1,4-dioxane and cVOC toxins in a drinking water supply. This Chemical Free, NSF 61 Certified, Advanced Oxidation Process (AOP+) is located between the ground water wells and clear well. Photo-Cat is fully automated, on demand, with 0-100% turn down capability process that is audited remotely via the Town’s Control Centre.
"Purifics demonstrated the Chemical Free capability of Photo-Cat to remove 1,4-dioxane and the client wanted to proceed with full-scale application immediately," explained Chris Johnson, of Environmental Management Services Inc., the client’s consultant.
Photo-Cat is a Photo-Catalytic Carbide Membrane process that combines the best of Chemical-Free Advanced Oxidation with Carbide-Ultra Filtration in a single unit operation to destroy chemicals and toxins while providing a multi-barrier disinfection capability.
Unlike chemical based, hydroxyl radical dependent AOPs that have a limited ability to treat refractive cVOCs, Purifics’ Photo-Cat process has a much higher oxidative potential and a reductive pathway giving it the ability to destroy chemicals other AOPs cannot. Additionally, Photo-Cat safely eliminates hazards, risks, liabilities, excessive footprint, GAC, annual lamp replacement and treatment train complexities, which provide unequaled OpEx and CapEx reduction.
"Purifics installed the first permitted 1,4-dioxane removal system in Ontario in 2002 and has developed a growing international reputation for this chemical free purification capability ever since," states Tony Powell, Applications Manager, Purifics.
A growing trend is that Water Boards and Regulators are raising concerns about the health effects of chemicals used in their water and the hidden Chemicals in Chemicals (CICs). One obvious example are the stabilizers in hydrogen peroxide used in the treatment of drinking water. It has become a growing concern among clients as to why drinking water facilities are adding higher magnitudes of these stabilizer chemicals from peroxide than the 1,4-dioxane stabilizer they are trying to remove.
