Determination of nanofiltrated membrane mass transfer resistance after separation of whey

Abstract

This paper presents the results of experimental studies to determine the mass transfer resistance of the new nanofiltrated membrane OPMN-P (JSC STC "Vladipor", Russia), and its mass transfer resistance after whey separation at the pressure of 2.5 MPa. It is found out that the value of mass transfer resistance formed by the interaction of solutes with the membrane is 5 times bigger than the resistance of the new membrane.
