Cross-flow velocity

Transmembrane pressure tested at constant cross-flow velocity

Result

1.1 L.min-1

4, 8,12, 16 psi`

50% of protein recovered in the permeate

2.2 L.min-1

10, 15, 22 psi

50% of protein recovered in the permeate

2.2 L.min-1

4 psi

No recovery in permeate, protein in retentate
