Impact/Purpose:
The widespread use of per- and polyfluoroalkyl substances (PFAS) over the last half century has resulted in these compounds being detected in both surface and ground water sources. Anion exchange (AEX) resins are being used extensively by the water industry to remove PFAS from drinking water sources. Due to the liability associated with PFAS residuals, many water utilities are incinerating single use AEX resins in cement kiln and waste to energy incinerators due to the waste streams associated with AEX resin regeneration. The study evaluates the feasibility of lime softening sludge reuse, generated from drinking water treatment utilities, as an additive during incineration of PFAS-laden resin, from drinking water treatment plants.
