A method for removing PFAS from a feed solution includes: flowing a feed solution comprising PFAS of varying chain lengths through a feed channel; applying a voltage to a first electrode and a second electrode in a redox channel separated from the feed channel by a first SEM, the first electrode becoming positively charged and the second electrode becoming negatively charged, wherein the PFAS in the feed solution transfer through the first SEM into the redox channel toward the first electrode; and separating PFAS based on chain length, wherein long-chain PFAS adhere to the first electrode through hydrophobic and electrostatic interactions, and short-chain to ultra-short chain PFAS migrate toward the second electrode in the redox channel and pass through a second SEM into an accumulating channel, thereby creating a PFAS-concentrated solution in the accumulating channel.
