Abstract
A waste treatment system for separating contaminants including per-fluoroalkyl and poly-fluoroalkyl substances (PFAS) from bulk solid waste (). A preparation module () having a bulk material separator separates oversize material () from bulk solid waste (). A physical separation module (), located down-stream of the preparation module (), separates the bulk solid waste () based on particle size using physical and/or hydrodynamic and/or density separation techniques. An extraction/chemical separation module (), located downstream of the physical separation module (), adds leachate and/or extractant to separate the contaminants from a slurry output from the physical separation module (), into a fines output and a contaminated water solution. A water circulation system () supplies water to the physical separation module () and the extraction/chemical separation module (), the water circulation system including at least one water treatment process, the treated water being recycled and recirculated within the waste treatment system.
