  • Removing metal ions from aqueous systems with an active layer membrane
    Patent number: 11117817
    Abstract: A process for removing metal ions from aqueous systems is disclosed comprising the treatment of the aqueous system with a membrane M, wherein the membrane M has a molecular weight cut-off above 3,000 Da and comprises A.) a carrier membrane CM, wherein said carrier membrane CM has a porous structure wherein the average pore diameter on one surface is smaller than in the rest of the membrane, thus forming rejection layers R on one side of carrier membrane CM, and B.) an active layer A comprising at least one polymer P comprising a plurality of functional groups G capable of forming stable complexes with metal ions selected from Ca, Mg, Al, Cu, Ni, Pb, Zn, Sb, Co, Cr, Cd, Hg and/or Ag, wherein said active layer A is located on the surfaces of the rejection layers R of carrier membrane CM and throughout the porous structure of carrier membrane CM.
