Title:
水からペル及びポリフルオロアルキル物質（ＰＦＡＳ）を除去し濃縮するための持続可能なシステム及び方法
Document Type and Number:
Japanese Patent JP6775667
Kind Code:
B2
Abstract:
A system for removing and concentrating per- and polyfluoroalkyl substances (PFAS), the system comprising:an anion exchange vessel including an anion exchange resin therein configured to remove PFAS;a line coupled to the anion exchange vessel configured to introduce a flow of water contaminated with PFAS such that the PFAS bind to the anion exchange resin and are thereby removed from the water;a regenerant solution line coupled to the anion exchange vessel configured to introduce a regenerant solution to the anion exchange vessel to remove PFAS from anion exchange resin thereby regenerating the anion exchange resin and generating a spent regenerant solution comprising the removed PFAS and the regenerant solution;a separation and recovery subsystem configured to recover the spent regenerant solution and separate and concentrate the removed PFAS to produce a concentrated PFAS solution; anda super-loading recovery subsystem configured to receive the concentrated PFAS solution and separate and further concentrate the removed PFAS by adsorbing the concentrated PFAS onto an additional anion exchange resin housed in an additional vessel to produce a PFAS waste product and a solution substantially without PFAS.
