The M-Series Ultrafillic* membranes are made of polyacrylonitrile (PAN) polymer. This membrane is characterized by a pore size of 0.01 microns with an approximate molecular weight cut-off of 20K-50K Dalton. To avoid fouling by “free” oils, the MW–series
elements have been engineered to be extremely hydrophilic (water attracting) as compared to conventional membranes that are oleophilic (oil
attracting).
MW Elements are used for oil/water separation and pretreatment of process water before reverse osmosis or nanofiltration.
