Synopsis:

• Novel clay-based adsorbent, FLUORO-SORB® 200 Adsorbent, was compared to three bituminous coal-based GAC adsorbents using RSSCT’s on contaminated groundwater samples to compare removal efficiency and media life determinations, overall FLUORO-SORB® Adsorbent had a significantly higher affinity for PFAS than GAC
• FLUORO-SORB® Adsorbent treated 2x more water (136 gal) than GAC (71 gal), with a lower simulated EBCT (2 min) than that required for treatment with GAC (7.5 min)
• Based on the shorter EBCT and media cost per pound FLUORO-SORB® has a lower capital and operational cost compared to GAC

Brief: RSSCT testing showed FLUORO-SORB® 200 Adsorbent to have superior PFAS affinity, operate at lower EBCTs, and have a greater capacity for PFAS than commonly used GAC sorbents. Additionally, due to the comparable cost per weight, FLUORO-SORB® 200 Adsorbent is said to also have a lower capital and operational cost than GAC
