The blood is pumped by way of a dialyzer or "hemofilter" as in dialysis, but no dialysate is utilized.

The blood flows in a single path plus the dialysate flows in the alternative. The counter-recent circulation with the blood and dialysis dialysate maximizes the concentration gradient of solutes between the blood and dialysate, which assists to eliminate far more urea and creatinine through the blood. The concentrations of solutes Commonly located in the urine (such as potassium, phosphorus and urea) are undesirably significant from the blood, but minimal or absent while in the dialysis Option, and consistent replacement of the dialysate makes certain that the focus of undesired solutes is held lower on this aspect from the membrane.
