WebPermeate is the filtrate from a membrane filter. It is called permeate due to the way that the feed water permeates through the membrane. Cross Flow vs. Dead End Flow Cross flow means that a small portion of the feed water is allowed to flow across the surface of the membrane (rather than through the membrane). WebNov 9, 2014 · It is generally suggested that the component permeation through a homogeneous membrane consists of five fundamental mutually dependent processes: (1) the solute molecules must first be transported or diffused through the liquid film (or gas film; in the later case the mass transfer resistance of the boundary layer is negligible … WebAcross the membrane, electrical potential increases from the feed side to the permeate side because of the higher concentration of cations than anions inside the membrane.
