Perkasie PFAS Treatment Reaches 200 Million Gallons, Reuses Activated Carbon for Long-Term Use

Perkasie Regional Authority's temporary PFAS treatment system has processed over 200 million gallons of drinking water in its first year. The system uses granular activated carbon from Sentinel Water Solutions and DESOTEC, allowing the utility to begin PFAS treatment a year before its permanent facility is ready. Instead of discarding the spent carbon, Perkasie plans to reactivate and reuse it, building an inventory of authority-owned GAC for the future plant. This reduces reliance on virgin carbon and cuts long-term material costs.

Interesting approach. Reusing the activated carbon for reactivation instead of buying new media is a smart way to cut both cost and waste. Would like to see numbers on how much carbon that actually saves over the life of the plant.

The 200 million gallons is impressive, but the real question is the energy footprint of running that GAC system. PFAS treatment can be power hungry. Any data on kWh per gallon or total operating cost?

This is also a regulatory story. With EPA's MCLs for PFAS now in effect, utilities are scrambling. A strategy like this shows you can start compliance early without waiting for permanent infrastructure.
