Look at the biological "Algal Turf Scrubber" approach, some companies are trying to claim the phrase, but there's much experimentation globally, and a lot of field test installations.

"review" and "systematic review" are also good keywords for research. /? 'PFAS remov' might be a better search term

> Perhaps most importantly, the particles in the Doyle group’s system can be regenerated and used over and over again. By simply soaking the particles in an ethanol bath, they can be washed of micropollutants for indefinite use without loss of efficacy. When activated carbon is used for water treatment, the activated carbon itself becomes contaminated with micropollutants and must be treated as toxic chemical waste and disposed of in special landfills. Over time, micropollutants in landfills will reenter the ecosystem, perpetuating the problem.
