BATTELLE Chlorinated Conference Reemerges with a Splash
The International Conference on Remediation of Chlorinated and Recalcitrant Compounds returned this year, and Battelle, the annual host, did not disappoint.
It was no surprise to see PFAS everywhere, especially because this conference focuses specifically on recalcitrant compounds. But now, with the huge breadth of data and tech available, the answer to PFAS contamination is more complex than ever. The dawn of the PFAS treatment and remediation market has clearly arrived, as evidenced by an expo full to the brim with technology vendors. From Granular Activated Carbon (GAC) and Anion Exchange resin (AIX) to foam fractionation and beyond, attendees were surrounded by old and new ways to protect the public from PFAS.
More than 1,500 technical experts from 27 countries descended on Palm Springs for the first time since the pandemic began, greeted by the largest technical program to date. It was a milestone Battelle event, with plenty of takeaways.
Insights and Observations
—The PFAS treatment market now includes a wide range of technologies, some ready for implementation, some more theoretical at this stage. Promising offerings included Battelle’s PFAS Annihilator and EPOC Enviro’s Surface Activation Foam Fractionation unit. Other approaches, like microbial degradation, seem to need more research and time to mature.
—GAC and AIX are still the most popular treatment options for drinking water providers. Having applied these technologies from bench-scale tests to design-build for new treatment facilities on the water side, we expect to see further application on the environmental front.
—Very compelling work is being done in evaluating PFAS groundwater plumes, specifically assessing how PFAS plumes compare to those from other chlorinated solvents. Discerning how PFAS plumes are alike or different from other contaminants will elucidate the best strategies for remediation.
—Big data has arrived for PFAS, leading the way to more analytical products. Which of these products are most relevant and promising? Our experts have been digging into the data, reach out for more information!
—Separate, Concentrate…Destroy: Technologies that can efficiently destroy PFAS represent the future of treatment and remediation. Destruction technology presented at Battelle included plasma, UV sulfite, supercritical water oxidation, hydrothermal alkaline and sonolysis.
