Engineering360: "A bubbly approach to PFAS-free water"

Perhaps an ultrasonic generator would be more efficient than the forced high velocity water?Cavitation can be achieved many ways,and when the bubbles collapse, it generates extremely high temperatures approaching the temperature of the surface of the sun.I can certainly understand how this would break down chemicals.

I can imagine an array of ultrasonic generators on the bottom of a clarifier basin,or an aerator basin.

I am sure this method has been considered by the experts in the field.

I know that a foaming detergent will weaken or destroy the cavitation action in an ultrasonic bath by preventing bubble collapse,so a non foaming detergent must be used to prevent bubble formation.

Perhaps this is the reason for their method of cavitation vs ultrasonic--the liquid is not conducive to ultrasonic pulses.

I hope eventually their method can be developed for multi-MGD treatment plants.

How about a small under sink or an in-line model for home use?

A simple mod of a commercial ultrasonic bath would work.I think I will work on that.
