Abstract
Convection promotion within a tubular ceramic membrane by using the Ke nics static mixer is studied. The experiments were carried out with aq ueous solutions of pectin and sodium carboxymethylcellulose (CMC), for Reynolds number in the range of 60-5000. From the results of these ex periments it can be concluded that the presence of convection promotor decreasing the concentration of the gel layer. The experimental data are correlated satisfactorily by the equation of the general form Sh = A (ReScb)-Sc-a.
