Abstract
A system and method provide improved ultrafiltration of charged/uncharged solutes in a fluid, especially a body fluid. The improvement is achieved through imposed electric field and/or surface charge patterning to a permeable membrane. In many of the embodiments, at least one selected material is used as an additive on a permeate side of the permeable membrane to reduce the sieving coefficient of the membrane with regard to a solute present in the fluid.
