Synopsis:
- FLUORO-SORB® 200 Adsorbent was evaluated in batch and column studies and compared to GAC for PFAS removal from both ground and surface drinking water sources of varying organic matter composition (0.2 to 4.75 mg/L DOC)
- FLUORO-SORB® Adsorbent reach 60% exhaustion for PFOA (1171 L/g) and PFBS (845 L/g) in the high DOC source water after filtering >8x more volume than GAC (60% exhaustion at 141 L/g and 95 L/g respectively), supporting that FLUORO-SORB® Adsorbent is minimally affected by matrix co-contaminants
- FLUORO-SORB® Adsorbent was observed to have faster sorption kinetics than GAC, with a lower equivalent full-scale empty bed contact time (2-min for FLUORO-SORB® Adsorbent, 10-min for GAC) indicating a smaller treatment system footprint
Brief: Batch and column scale studies indicate FLUORO-SORB® Adsorbent has superior performance for PFAS sequestration from ground and surface waters as compared to GAC, especially in waters with high organic co-contaminant levels (4.75 mg/L DOC). FLUORO-SORB® Adsorbent was shown to operate at 2-minute equivalent full-scale empty bed contact time, indicating a smaller overall footprint requirement for remediation efforts.
