The present disclosure includes systems, devices, and methods for a reactor, such as a sonication reactor, for destruction of Per- and polyfluoroalkyl substances (PFASs). In one aspect of the disclosure, the reactor includes a housing having a base and one or more walls that cooperate to define a chamber and a transducer disposed the chamber. The transducer is configured to generate a plurality of sound waves such that when PFAS solution is disposed within the chamber, the sound waves propagate through the liquid and at least some of the one or more PFAS compounds are pyrolyzed or otherwise degraded. Other aspects and features are also claimed and described.

A solvent extraction process for removing poly- and perfluoroalkyl substances (PFAS) from a PFAS laden adsorbent is disclosed. The process comprises introducing a substantially pure solvent at an elevated temperature to a bed of the PFAS laden adsorbent and continuously removing PFAS laden solvent from the adsorbent, wherein the introducing and removing are carried out simultaneously and continuously until a desired amount of PFAS is removed from the adsorbent. Also disclosed is a process for degrading poly- and perfluoroalkyl substances (PFAS) to environmentally benign products. The process comprises providing an aqueous solution containing PFAS at a concentration of greater than 50 ppm; and subjecting the aqueous solution to ultrasound using at least one ultrasonic transducer at a frequency and power and for a time sufficient to degrade substantially all of the PFAS in the solution to carbon dioxide and fluoride.

According to one embodiment, a treatment method may include making a byproduct come into contact with a treatment solution, wherein the byproduct is a solid or liquid byproduct formed by polymerizing components contained in an exhaust gas discharged by synthesizing a silicon-containing material using a gas which includes silicon and halogen. The treatment solution may include at least one of an inorganic base or an organic base, and is basic.
