Stubborn compounds called PFAS in drinking water put health at risk. Technologies based on plasmas, pressure, sound or fungus could finally degrade these chemicals.
it's like how they finally figured out who mr Swirl was...seems like plasma and pfas woulda been tested long ago but, hey, steps forward are to be rewarded.
I think the key is using argon bubbles as a method of nucleation for the PFAS as well as an efficient medium for the plasma to be carried to the chemical. I'd imagine it would function like a neon light with water and a bubbler in it.
Making something like this likely wouldn't have been high on the list of first things to try, especially when applying it to an entire world of contaminated water.
