Overview of membrane filters
An overview of the different pressure-driven membrane filtration processes.
Apart from typical applications of the individual filter types, this tabular overview also lists the main parameters. Plastic is generally used as the filter material, although metal and ceramic membranes are also possible in principle. Depending on the size of the particles to be separated out and the pore size of the membrane the filtration process is referred to as microfiltration, ultrafiltration, nanofiltration or reverse osmosis. The smaller the pores are, the greater the applied pressure difference has to be in order to force the water through the membrane.
