Abstract
Membrane separation is a relatively new technology, but already is playing an increasingly important role in many industries, including the chemical, pulp and paper, pharmaceutical, dairy, and water treatment industries. Ultrafiltration (UF) is a pressure-driven membrane separation technique. UF, usually conducted at low to medium pressure, has separation capabilities spanning the upper limits of the ionic range through the macromolecular range and into the micron-particle range, that is, from 20 to 100 000 Å (Moes 1987). It has been applied successfully to fractionation of kraft lignin (Forss and Fuhrman 1978, Hill and Fricke 1984), and lignosulfonates (Collins et al. 1977).
