PFAS Remediation and Removal
PFAS Removal Solutions for Soil, Groundwater and Drinking Water
What is PFAS? PFAS stands for Poly- and perfluoroalkyl substances representing thousands of synthetic chemicals that repel water, oil, and grease. Simply put, PFAS is a “forever chemical”. As a result, PFAS have been integrated into dozens of industry and consumer products over the past 60 years, making their presence rather ubiquitous throughout nature. Advanced Environmental Control along with their product manufacturer are tackling the issue.
What are PFAS?
Over the past 60 years, PFAS have been integrated into dozens of industrial and consumer products. PFAS have been used in common products, including non-stick cookware, clothing materials, carpets, firefighting foams (aqueous film forming foam – AFFF), and various other products designed to resist grease, water, and oil. PFAS have a strong carbon-fluorine chemical bonds that prevent their breakdown in nature and eventually allowing them to enter the water supply.
As a result, scientists have been studying the health impact of PFAS, concluding that exposure causes numerous health effects.
What is considered safe levels of PFAS?
The Environmental Protection Agency (EPA) recently established PFAS screening values of 40 parts per trillion (ppt) and has proposed a Reasonable Progress Goal (RPG) of 70 ppt. Although this may be a base standard for the EPA, some states have set more rigorous Maximum Concentration Limits (MCLs) and others are considering doing the same.
Other agencies such as the Centers for Disease Control (CDC) recommends that “if your drinking water is contaminated, use an alternate source when the water may be swallowed. Contamination is considered any level above those specified by the EPA or your state government.
How to remove PFAS
Now there are products that have been developed and used to filter PFAS, but they are limited by their high cost or short lifespan. Furthermore, their effectiveness can be affected by various factors, such as water chemistry, pH, or the presence of co-contaminants. Since PFAS can assume various forms (PFOA, PFOS, PFHS, and PFNA to name a few), the stated technology must be effective across the broad spectrum of PFAS. Our product manufacturer has this search as their main focus.
Our product manufacture has been able to come up with the best solution for this treatment, FLUORO-SORB®. FLUORO-SORB® is a proprietary, NSF-certified product that effectively treats multiple variants of PFAS. Unlike other sorbent products that are selective and unpredictable in adsorbing PFAS, FLUORO-SORB adsorbent binds the entire spectrum of PFAS efficiently and in a wide variety of removal and remediation processes. FLUORO-SORB adsorbent can control the source of contamination via a Permeable Reactive Barrier (PRB) or In Situ Stabilization and Solidification (ISS). It can be deployed easily as a flow through treatment media, either on its own or as a pre- or post-treatment in connection with your existing water treatment train, with an Empty Bed Contact Time (EBCT) as low as 3 minutes.
FLUORO-SORB adsorbent resists competitive adsorption from other water and sediment contaminants. Due to its higher sorption kinetics and capacity, it has been proven to be 3-4 times more adsorptive than granular activated carbon (GAC), thereby reducing the number of changeouts requires for a positive impact on operational costs and lower disposal costs for spent media.
Our product manufacturer is the leader and pioneer in cutting-edge environmental products and solutions. Their team of mineralogists, polymer scientist and chemist are the leaders of transforming ordinary minerals into superior technology capable of solving everyday problems on a worldwide scale.
