Abstract:
A membrane for purifying a liquid stream includes a porous substrate and alternating layers of positively charged material and negatively charged material adhered to the porous substrate, wherein at least two of the layers of charged materials possess free ion exchange capacity.

Claim (Index 35):
A method for the production of a membrane, said method comprising:\n depositing a polymeric solution comprising a polymer and a first solvent in which the polymer is soluble on a fibrous support to produce a film having a thickness from about 50 to 300 microns on the fibrous support; immersing the fibrous support and film of polymeric solution in a non-solvent bath in which the polymer is insoluble, wherein the non-solvent bath induces a non-solvent phase separation of the polymeric solution to yield a porous substrate comprising the fibrous support coated with the polymer; and depositing at least three alternating layers of polycationic and polyanionic solutions with layer thicknesses of 4 to 35 microns on the porous substrate to form charged material layers.
