3. It is desired to increase the protein concentration in whey, by a factor of 10 by using ultrafiltration to give an enriched fraction which can subsequently be spray dried to produce whey protein powder. The whey initially contains 6% of total solids, 12% of these being protein. The pilot plant experiments show that protein concentration at membrane surface is 25%. The ultrafiltration system contains 10 tubes with 1.0 cm diameter. The desired processing rate is 1000 Kg/hr of feed solution. Mass transfer coefficient, Km is estimated to be 2.71 x 10^6 m/s
