In an ultrafiltration plant, whey is to be concentrated. Two streams are to be

produced, a protein rich stream and a liquid stream (mainly water). In all

140,000 kg per day are to be processed to give a 12-fold concentration of 95%

of the protein from an original whey concentration of 0.93% protein and 6% of

other soluble solids. Assuming that all of the soluble solids other than protein

remain with the liquid stream, which also has 5% of the protein in it, estimate

the daily flows and concentrations of the two product streams.
