ABSTRACT:
An apparatus and method for purifying a fluid stream employ a bed of regeable ligands affixed to one side of a semipermeable membrane. A ligate-laden fluid stream is conducted along the one membrane side, and the ligands selectively remove the ligates from the fluid stream by adsorption. A regeneration agent is conveyed to the ligand bed by diffusion across the membrane to break the ligand-ligate bonds and free the ligates. The freed ligates are rinsed from the vicinity of the regenerated ligand bed, which is now capable of adsorbing additional ligates.
