Membrane filtration can be carried out by means of two operating modes: dead-end filtration and cross-flow filtration (Fig. 2).In dead-end filtration, the feed stream flows perpendicular to the membrane and is forced through the membrane. In consequence, the retained components accumulate on the membrane surface forming a cake layer, resulting in a decrease of the …
