USE OF A ROTATING FILTER TO ENHANCE CERAMIC MEMBRANE FILTRATION PERFORMANCE OF LATEX DISPERSIONS

The performances of both the tangential crossflow system and the rotat ing system with a tubular microfiltration ceramic membrane were invest igated experimentally in the separation of latex dispersions. In addit ion, the shear rate at the membrane surface for azimuthal flow in an a nnulus with a porous wall on the rotating inner cylinder was solved fo r the narrow-gap approximation. In contrast to the tangential crossflo w system, the rotary system was characterized by a significantly highe r flux. The increase in the membrane flux was achieved at shear rates less than those for the crossflow system investigated.
