Abstract

A regenerative peritoneal dialysis system includes a dialysis fluid loop; a filter located in the dialysis fluid loop, a first portion of the dialysis fluid sent to the filter rejected by the filter and returned upstream of the filter, a second portion of the dialysis fluid sent to the filter forming permeate, the permeate being rich in urea; and a urea removing apparatus located in the dialysis fluid loop downstream from the filter to receive the permeate and absorb urea from the permeate.
