Fate of PFAS Through a Biosolids Drum Dryer With Regenerative Thermal Oxidizer Emissions Control.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Thermal dryers are commonly used for biosolids volume reduction and stabilization, but the fate of PFAS in these systems is not well understood. Triplicate samples from a full-scale rotary drum dryer were evaluated, including gas-phase emissions before and after a regenerative thermal oxidizer used for emissions control. Substantial PFAS removal between the feed and dried solids (60.0% on a total molar basis for targeted PFAS) was observed. PFAS did not accumulate in the drain water from wet scrubbers treating dryer exhaust. The scrubbed exhaust contained six orders of magnitude less PFAS than the dewatered feed solids on a total molar mass basis. The destruction or removal efficiency of PFAS across the RTO was complicated by contaminant-prone and thermally unstable HFPO-DA, achieving 93.5% when including the suspect compound and 99.3% when not. Further research is needed to identify potential transformation mechanisms and products to close the PFAS balance across drying processes.
