PFAS Removal

 

 
 
 

Efficient PFAS Removal with Sunresin Ion Exchange Technology

Advanced solutions for removing "forever chemicals" from water sources, ensuring safety and sustainability.

 

The PFAS Challenge

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are persistent, hazardous chemicals that pose growing health risks through drinking water, surface water, and industrial discharges. Known as "forever chemicals" due to their resistance to degradation, PFAS have been linked to serious health issues including immune suppression, thyroid disorders, liver damage, and reproductive problems—even at extremely low concentrations.

Why Ion Exchange for PFAS Removal

Sunresin’s ion exchange technology offers a high-performance solution for the selective removal of PFAS from both drinking and industrial water.

How It Works

Our specially engineered anion exchange resins feature quaternary ammonium functional groups that selectively attract and bind negatively charged PFAS molecules—including long-chain compounds like PFOA and PFOS, as well as the increasingly concerning short-chain variants.

 

Selective Binding

Resins designed to target PFAS molecules specifically

 

Efficient Removal

Removes PFAS to parts per trillion (ppt) levels

 

Regenerative Process

Resins can be regenerated for repeated use

Key Advantages

Compared to traditional technologies such as Granular Activated Carbon (GAC) or Reverse Osmosis (RO), ion exchange provides distinct advantages:

  •  

    Faster Adsorption

    Faster PFAS adsorption kinetics than GAC

  •  

    Higher Selectivity

    Higher capacity for both short- and long-chain PFAS

  •  

    Compact Design

    Smaller system footprint, reducing space demands

  •  

    Long Lifespan

    Longer operational lifespan under low-concentration conditions
