Tubular ultrafiltration membranes were used to investigate mass transfer characteristics of whey solutions. The effects of bulk concn. and flow velocity on permeate flux, mass transfer coeff. and apparent rejection coeff. were measured. Mass transfer coeff. (k) increased linearly with increasing flow velocity, and the following relationship between k and linear velocity (u, cm/s) was obtained: k = 0.87 x 10-5u1.1.
