Flow Rate Calculation
The flux or flow rate in cross-flow filtration systems is given by the equation:
in which:
- : liquid flux
- : transmembrane pressure (should also include effects of osmotic pressure for reverse osmosis membranes)
- : Resistance of the membrane (related to overall porosity)
- : Resistance of the cake (variable; related to membrane fouling)
- : liquid viscosity
Note: and include the inverse of the membrane surface area in their derivation; thus, flux increases with increasing membrane area.
