How to Remove PFAS from Water: Technologies and Solutions

Per- and polyfluoroalkyl substances (PFAS) are a group of toxic synthetic chemicals widely used in industrial applications and consumer products. Often called “forever chemicals” due to their resistance to degradation, PFAS have been detected in drinking water across the globe. Long-term exposure to PFAS has been linked to serious health effects, including cancer, hormone disruption, and immune system damage.

At Matregenix, we are at the forefront of developing advanced materials to tackle environmental challenges like PFAS removal from water. In this blog, we’ll explore the best available technologies and emerging solutions for eliminating PFAS from contaminated water sources.

Understanding the PFAS Challenge

PFAS are extremely persistent in the environment due to the strength of the carbon-fluorine bonds in their molecular structure. Traditional water treatment methods like chlorination or biological filtration are ineffective at removing PFAS. Therefore, specialized technologies are necessary to protect water supplies from these harmful substances.

Proven Technologies for PFAS Removal from Water

1. Activated Carbon Filtration

Granular Activated Carbon (GAC) is one of the most commonly used methods for PFAS removal. It works by adsorbing PFAS molecules onto its porous surface. GAC is especially effective for long-chain PFAS compounds, such as PFOA and PFOS.

However, its effectiveness can decrease in the presence of short-chain PFAS or when organic matter in the water competes for adsorption sites. Regular replacement or regeneration of the carbon media is also necessary to maintain performance.

2. Ion Exchange Resins

Ion exchange systems use specially designed resins to remove PFAS by swapping ions in the resin with PFAS molecules in the water. This method offers higher efficiency than GAC, particularly for both long- and short-chain PFAS compounds.

Ion exchange is faster and requires smaller treatment footprints, making it suitable for high-flow applications. The resin can be regenerated, but it eventually needs replacement as it becomes saturated with contaminants.

3. Reverse Osmosis (RO)

Reverse osmosis membranes effectively remove PFAS by forcing water through a semi-permeable membrane that blocks contaminants. RO is highly effective at reducing a broad spectrum of PFAS compounds, including those with shorter chains.

While reverse osmosis delivers high purity, it comes with higher costs, energy consumption, and brine management issues. It’s best suited for point-of-use systems or smaller community treatment facilities.

Emerging and Advanced Solutions

1. Nanofiber-Based Filtration

At Matregenix, we specialize in nanofiber technology that is revolutionizing water filtration. Our engineered nanofiber membranes offer high surface area, customizable pore sizes, and enhanced selectivity, making them ideal for capturing even the smallest PFAS molecules.

Nanofiber filtration enables a more efficient, scalable, and sustainable method of PFAS removal from water. Unlike traditional filters, our advanced membranes can be tailored to target specific contaminants while maintaining high water flow rates and low energy consumption.

2. Advanced Oxidation Processes (AOPs)

Emerging AOP technologies aim to break down PFAS molecules using a combination of oxidants, UV light, or plasma. While still under development for commercial use, AOPs offer the potential to destroy PFAS rather than simply remove or concentrate them.
