The breakthrough of MF in the dairy industry came in the 1980s with the devel-opment of new ceramic membranes com-prising a multichannel geometry and a highly permeable support [15] which made industrially feasible the revolutionary hydraulic concept proposed by Sandblom[47]: the uniform and low transmembrane pressure (UTP). The UTP concept over-comes most of the heterogeneous fouling of the MF membrane which results from the high cross flow velocities required for obtaining both high permeation fluxes and accurate selectivity
