Synopsis:

• Design of rapid small scale column tests (RSSCT) were determined based on bench-scale columns with FLUORO-SORB® Adsorbent, which has already been well defined for other adsorbents (GAC, ion exchange (AER))
• Constant diffusivity and the Thomas model were determined to be sufficient estimation models for scalability of FLUORO-SORB® Adsorbent, with a key consideration in uptake per unit surface area
• Projections for full-scale operation indicate FLUORO-SORB® Adsorbent would outperform the two GAC and two AER resin. FLUORO-SORB® Adsorbent was found to operate with similar EBCT’s and efficiency to AER, while characterized by a lower media cost than AER

Brief: A mechanistic evaluation of RSSCTs for FLUORO-SORB® Adsorbent PFAS removal efficiency were defined for future scalability and efficacy determinations for water treatment technologies. GAC (2) and AER (2) media were compared to FLUORO-SORB® Adsorbent which was found to have strong removal efficiency and cost effectiveness making it a promising alternative technology.
