Dialysis vs. Ultrafiltration

Dialysisnoun

(chemistry) A method of separating molecules or particles of different sizes by differential diffusion through a semipermeable membrane.

Ultrafiltrationnoun

Filtration through a semipermeable membrane that only allows small molecules through.

Dialysisnoun

(medicine) Utilization of this method for removal of waste products from the blood in the case of kidney failure: hemodialysis or peritoneal dialysis.

Ultrafiltration

Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the so-called retentate, while water and low molecular weight solutes pass through the membrane in the permeate (filtrate).

Dialysisnoun

(rhetoric) The spelling out of alternatives, or presenting of either-or arguments that lead to a conclusion.

Dialysisnoun

(rhetoric) Asyndeton.

Debility.

Dialysisnoun

Dialysisnoun

separation of substances in solution by means of their unequal diffusion through semipermeable membranes

Dialysis

In medicine, dialysis is the process of removing excess water, solutes, and toxins from the blood in people whose kidneys can no longer perform these functions naturally. This is referred to as renal replacement therapy.
