De Nora showed off a new PFAS removal system at WEFTEC 2024 in New Orleans that can utilize either granular activated carbon (GAC) or ion-exchange (IX).
Thomas Muilenberg, global product manager water technologies business at De Nora, said that the new Sorb FX treatment system can use either GAC or IX depending on the application size and the flow rates.
The system can also be configured depending on what contaminants are found in the water other than PFAS.
GAC may be more benefical for a treatment system that sees more organic chemicals while IX may be more beneficial for a system that has more calcium, all while removing PFAS from the water.
The system can use mutiple sensors along the media vessels to detect PFAS levels. Muilenberg said that once higher levels are detected in one of the media vessels, you can isolate it, change the media, and reverse the flow, allowing contaminated water to move through the oldest media, optimizing the life.
The system has a unique underdrain approach that uses patented technology to cut down on deadzones at the bottom of the tank.
The system is set up for lead-lag, parallel or series operation.
Capacity of the system can range up to 2,800 GPM and is BABA compliant.
The company is currently doing a pilot program with the new product that can help utilities determine what size system is right for them. The pilot program can come in a smaller size, like the model displayed at WEFTEC, or it can come pre installed inside of a shipping container for a larger pilot program.
