Managing PFAS in semiconductor wastewater often requires more than a single treatment step. This presentation takes a system-level look at how different PFAS behave through characterization, concentration, capture, and destruction processes, and why treatment trains must be tailored to both chemistry and operating conditions. Drawing on piloting and field experience, it discusses practical combinations of membranes, foam fractionation, sorbents, and destruction technologies, along with lessons learned around scaling, residuals handling, and long-term disposal strategies.
