METHOD AND APPARATUS FOR LIMITING DIAFILTRATE WASTE

摘要

The present invention describes a process and a device for saving diafiltrate by partial regeneration using adsorbers. An object of the invention is to decrease the requirement of dialysate and/or substituate in the depletion of a substance of class X by means of special microstructured adsorption/filtration devices. An object of the invention is also to enable control of the concentration of a substance group X by hemodialysis and/or hemofiltration, such that by partial recirculation of the diafiltrate in the regeneration circuit, the net throughput of diafiltrate can be kept lower. The process serves for saving dialysate and/or substituate solution in control of the concentration of a substance group X in a complex biological liquid compartment, wherein the net throughput of dialysate and/or substituate is minimized by some of the diafiltrate being regenerated by an internal regeneration cycle (RKL) which is able to deplete substrates or products (substance group Y) of the substance group X in the biological liquid compartment.
