Special emphasis has been made on the critical analysis of the membrane separation methods which are currently accepted as the most viable methods for whey protein recovery.
Membrane separation methods such as electrodialysis (ED) can reduce the volume load on evaporators by facilitating further concentration of rejects from reverse osmosis (RO) plants.
In this review, different membrane separation methods including microfiltration, ultrafiltration, nanofiltration and reverse osmosis for fruit juice clarification/concentration reported in the literature in the last fifteen years are discussed.
The advantages of membrane separation methods, such as membrane distillation and pervaporation, include low energy demand, no removal of nutrients and substrates, no need for an entrainer, and a low possibility of contamination [ 16– 16].
Dialysis, a technique frequently used in biochemistry, is a membrane-separation method used for removing dissolved salts from solutions of proteins or other large molecules.
Advantages of membrane-absorptive separation method realized in membrane contactors are relative construction simplicity, reliability, high parameters of separation, lower energy consumption and absence of high-pressure drop.
As the result of intensification method, membrane separation was suggested and applied to the design.
Of these methods, membrane separation appears to be a suitable process based on overall separation performance.
To circumvent the water wash purification method, a membrane separation system using ceramic membranes was designed, constructed and tested for the removal of glycerol from crude FAME from a biodiesel production process.
Membrane separation has the advantage over other separation methods in that it is simple and potentially less energy intensive.
Crude W/O emulsions can be broken down using different methods, such as membrane separation, ionic liquids, ultra-centrifugation and electro-sedimentation (Feng et al. 2009).
