The addition of inert dispersant (e.g., SiO2) to provide extra collision surfaces and the preevaporation of solvents were demonstrated as two feasible options to promote AFFF treatment capacity. Evaporation could be realized on commercial evaporators using waste heat or solar energy. It is important to note that evaporation was introduced as an example. Other PFAS concentration approaches could also be adopted. As for the BM treatment, we used 100 mL jars filled with BN (0.5 g) and SiO2 (5 g) at a balls/reagents mass ratio of 29 to treat 100-1000 μL AFFF. We previously calculated that the force induced by steel ball collision in our planetary ball mill is 57 N. These parameters lay the groundwork for the optimization and design of scaled-up systems in our following studies. Should these parameters (impact force, balls to feedstock mass ratio, [BN mass]/[AFFF volume] ratio, etc.) be reproduced on a commercial ball mill and the CLFT criteria be met, the on-site disposal of large volume undiluted AFFF can be expected.
