A variety of methods employing easily accessible spreadsheet and graphical tools are used for the analysis, design, and optimization of the industrially important unit operation of continuous feed and bleed ultrafiltration. The gel polarization model is a subset of concentration polarization theory in which the convective flux of solute towards the membrane is balanced by diffusion of solute from the membrane back into the bulk flow. The key result of the concentration polarization analysis is that the flux is related to the solute concentration at the membrane. The concentration is a function of transmembrane pressure, but at high pressures where the flux is constant and equal to its limiting value it can be assumed that the solute concentration at the membrane reaches a limiting value. It is assumed that the membrane area, the feed flowrate, the feed concentration, and the mass transfer coefficient are known and constant.
