Introfuction Of Membrane Filtration

    Though membrane filtration was not considered a technically important separation process until 30 years ago, today membrane processes are used in a wide range of applications and the number of such applications is still growing. From an economic point of view, the present time is intermediate between the development of first generation membrane processes such as microfiltration(MF), ultrafiltration(UF), nanofiltration(NF), reverse osmosis(RO), eletrodialysis(ED), diffusion dialysis(DD), and dialysis and second generation membrane processes such as  gas separation(GS), vapour permeation(VP), pervaporation(PV), membrane distillation(MD), membrane contactors(MC) and carrier mediated processes. Though there are many membrane processes, based on different separation principles or mechanisms and specific problems can cover the broad size range from particles to molecules, all membrane processes have one thing in common, the membrane.

    As to the syringe filters, it belongs to the microfiltration(MF), Microfiltration is a separation process by using the pressure difference, and the membrane pore range is 0.05um to 20um.
