Membrane technology encompasses the scientific processes used in the construction and application of membranes. Membranes are used to facilitate the transport or rejection of substances between mediums, and the mechanical separation of gas and liquid streams. In the simplest case, filtration … Visa mer Membrane technology covers all engineering approaches for the transport of substances between two fractions with the help of semi-permeable membranes. In general, mechanical separation processes for separating … Visa mer According to the driving force of the operation it is possible to distinguish: • Pressure driven operations • Concentration driven operations • Operations in an electric potential gradient Visa mer The selection of synthetic membranes for a targeted separation process is usually based on few requirements. Membranes have to provide enough mass transfer area to process large amounts of feed stream. The selected membrane has to have high Visa mer Two basic models can be distinguished for mass transfer through the membrane: • the solution-diffusion model and • the hydrodynamic model. Visa mer There are two main flow configurations of membrane processes: cross-flow (or tangential flow) and dead-end filtrations. In cross-flow filtration … Visa mer Membrane separation processes have a very important role in the separation industry. Nevertheless, they were not considered … Visa mer The pore sizes of technical membranes are specified differently depending on the manufacturer. One common distinction is by nominal pore size.
