Why should we need the Characterization of membranes?

¨

-Membranes need to be characterized to ascertain which may used for a certain separation or class of separations.

-The information obtained from characterization measurements will help us in the prediction of membrane performance for a given application. One useful piece of information is a distinction between intrinsic membrane properties and actual membrane applications. For example, the membrane flux for ultrafiltration in food- and dairy applications is usually less than 10% of the pure water flux, with the application of microfiltration giving an even larger difference between the pure water flux and process fluxes. The large discrepancy is mainly caused by concentration polarization and fouling.

- Membrane characterization is necessary to relate membrane structure to transport phenomena, in an effort to provide a greater understanding of separation problems and possibly predict the kind of structure needed for a given separation. ¨

- Membrane characterization leads to the determination of structural and morphological properties of a given membrane.

-Membrane characterization is necessary to relate structural membrane properties such as pore size, pore size distribution, free volume and crystallinity to membrane separation properties.

When you choose the syringe filters, you should know the menbrane characterization of the syringe filters, then you can find the suitable one for your application.
