Problem 3 Time for Ultrafiltration Using Recirculation. It is desired to use ultrafiltration for 1800 kg of a solution containing 0.25 wt% of a protein to obtain a solution of 2.1 wt%. The feed is recirculated past the membrane with a surface area of 15.6 m². The permeability of the membrane is Aw = 3.3 x 102 kg/s-m²-atm. Neglecting the effects of concentration polarization, if any, calculate the final amount of solution and the time to achieve this, using a pressure difference of 0.96 atm.
