Hemodiafiltration with ultrafiltrate regeneration by adsorption in resin. (A) High-permeability filter with a polyphenylene membrane surface of 0.7 m² (B) Resin cartridge with a high affinity for κ and λ (C) Low-permeability filter with a polyphenylene membrane surface of 1.7 m². The blood flows into the A filter initially, where convection is performed, and the produced ultrafiltrate transits the B cartridge, where adsorption takes place, before passing through the C filter, where diffusion is carried out.
