MW Series
Industrial Oil/Water Separation UF Elements
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 ex-
tremely hydrophilic (water attracting) as compared
to conventional membranes that are oleophilic (oil
attracting).
MW Elements are used for oil/water separation and
suspended solids removal. They are also used as
pretreatment of process water before reverse os-
mosis or nanofiltration.

The element diameter (dimension C) is designed for optimum performance in GE
pressure vessels. Others pressure vessel dimension and tolerance may result in
excessive bypass and loss of capacity.

tion of materials compatible with the content of the high-
ly concentrated solution.
