Rapid Small-Scale Column Tests for PFAS Treatment Evaluation

PFAS (per- and polyfluoroalkyl substances) contamination is an ongoing challenge in water treatment, requiring careful selection of the most effective treatment technologies. In her insightful article, “Rapid Small-Scale Column Tests for PFAS Treatment Evaluation,” Rosa Yu, PhD, PE, a lead technologist at Carollo Engineers, delves into the use of Rapid Small-Scale Column Tests (RSSCTs), an innovative tool for evaluating PFAS treatment options like granular activated carbon (GAC) and ion exchange (IX) resin.

Traditional pilot studies are often employed to predict the effectiveness of these treatment technologies, but they come with significant drawbacks. These studies can take months or even years to complete, delaying crucial decisions and potentially driving up costs. In contrast, RSSCTs offer a much faster and more cost-effective alternative. By utilizing mini-columns and smaller-sized media, RSSCTs can compress the timeline of full-scale adsorber operations by up to 50 times. This means that what would typically take 30 months at full scale can be achieved in just 2.5 weeks at the bench scale.

The rapid turnaround provided by RSSCTs is a game-changer for water treatment professionals, allowing them to make informed decisions more quickly and with greater confidence. This approach not only speeds up the evaluation process but also leads to more accurate predictions of full-scale performance, ultimately saving both time and money.

Carollo is at the forefront of this innovative approach. At our Water Applied Research Center (Water ARC®) in Boise, Idaho, we are fully equipped to conduct RSSCTs tailored to specific needs. Our expertise in PFAS treatment and advanced testing methods enables us to provide customized, effective solutions that address the unique challenges of PFAS contamination.
