A process for producing a protein concentrate is shown schematically below. The fluid that is fed has a protein concentration of 16%. Two successive filtration operations are carried out, in which a permeate and a retentate are produced. In the second operation, the permeate (0% protein) is divided into two: waste and recycling (which is returned to the first operation). Calculate the flows X, Y and Z, as well as the concentration of the finished product (W).
