Abstract

A method and a system for regenerating a body fluid, such as a peritoneal dialysis fluid. The body fluid is removed into an extracorporeal circuit comprising an electrofilter for removing charged ions from the body fluid, a nanofilter for removing large molecules, such as Dextran 40, and a reverse osmosis filter for concentrating the body fluid, for producing a synthetic urine to be discarded. The removed ions and large molecules are returned to the patient together with pure water from the reverse osmosis filter through an ultrafilter.
