Vortex Flow Filtration for Ultrafiltration of Protein Solutions
The induction of secondary flow by Taylor vortices during ultrafiltration of protein solutions provides a means to enhance this unit operation. Vortex flow filtration is readily implemented by placing a membrane on a high speed rotating cylinder in a narrow annular gap. The resulting increase in mass transfer coefficient makes the filtration dependent on membrane properties such that filtration flux is controlled by membrane permeability and protein transmission is enhanced.
