Treatment of Bleaching Effluents by Pressure Driven

Most pressure-driven membrane processes are operated in the cross-flow fltration mode. In this process, the feed solution flows tangentially to the membrane surface. At the membrane surface, the permeating component moves perpendicularly to the membrane surface.

Comparison of pressure-driven membrane processes and

vapour is driven by differences in vapour pressure. Hot feed water flows alongside a nano structured membrane. The surface tension of the feed prevents it, while in a liquid state, from entering the non-wettable (hydrophobic) membrane. Instead, part of the water evaporates and, as vapor, passes through the pores of the membrane, then condenses on the other side of the membrane. Non-volatile

Pressure driven membranes have been classified into four categories based on the membrane rejection properties as follows: Microfiltration (MF) membranes - have the largest pore size (0.1 - 3 micron), require low transmembrane pressure (1- 30 psi), and are used for turbidity reduction, removal of suspended solids, parasites (e.g. giardia and

Osmotically and thermally driven membrane processes for

Pressure-driven membrane processes are defined as processes in which the feed stream is fed at a volumetric rate Q f into a membrane device (e.g., pressure vessel) equipped with membranes that divide the device space into a feed side and a permeate side, and in which a pressure difference across the membranes causes the solvent (usually water) to pass from the feed space to the permeate …

Pressure Driven Membrane Processes kosalmath

Electrically driven membrane processes are widely used to remove charged components from a given feed solution or suspension. Thus the applied driving force is a voltage difference and the components that are removed are ions. In contrast to pressure driven membrane processes where you have a volume flux through the membrane, you have a flux of ions through the membrane in electrically driven

The four main pressure driven membrane processes now in use in the dairy industry are ultrafiltration, reverse osmosis, microfiltration and nanofiltration. This monograph focuses on performance, which is a key issue in the use of membrane processes by the industry. The title reflects the two major subjects involved in the performance. An attempt is made to narrow the gap between factory
