The present work indicates the organic nf membranes and the inorganic nf membranes all have shortages, so develop composite nf membranes that have low cost, mechanically strong and thermally / chemically - resistant, easy to cleanout and good performances is a very important task. in this paper, the preparation of inorganic - organic composite nf membranes were presented. this composite comprise a porous sio2 / al2o3 support substrate, the pore diameters of which ranging from 10 to 15 nm, this inorganic support substrate having a polymer membrane which comprises an polyvinyl alcohol ( pva ) or polyamide ( pa ) densely deposited on at least one of the face surfaces thereof, the structural porosity of such pva and pa membrane ranging from 3 to 5 nm
