A hollow fiber membrane separator with a nominalmolecular weight cutoff of 100,000 is fed a solution of proteins atthe rate of 250 mL min-1 . The composition of the protein solutionis protein A (4 g/L, MW=20,000), protein B (7 g/L, MW=150,000), andprotein C (6 g/L, MW=300,000). The filtrate flow rate is found tobe 116.4 mL min-1 and the flow rate of the retentate is 133.5 mLmin-1 . The concentration of protein A in the retentate is found tobe 5.84 g/L. What is the concentration of protein A in thefiltrate? Also, what are the concentrations of proteins B and C inthe filtrate and in the retentate?
