- Diluted skim milk with a protein concentration of 4.3 g/L is to undergoDEF microfiltration. Experiments have been performed using a cellulose-acetate membrane with an average pore diameter of 0.45 µm and AM = 17.3 cm2. For Stage 1 operation at a constant-permeate rate of 15 mL/minute, pressure drop across the cake and membrane increases from 0.3 psi to an upper limit of 20 psi in 400 seconds. The permeate viscosity is 1 cP. If continued in a second stage at constant ∆P at the upper limit until the permeate rate drops to 5 mL/minute, estimate the additional time of operation.Prepare plots of permeate volume in mL and permeate flux in mL/cm2-minute as functions of time.W00d chips are t0 be dried in a r0tary drier fr0m 35% m0isture to 12% m0isture.
