  • Bilayer polyamide desalination membrane
    Patent number: 11684895
    Abstract: A composite reverse osmosis membrane having a semipermeable bilayer polyamide composition comprising a base layer containing a rigid crosslinked aromatic polyamide and a top layer containing a flexible aliphatic polyamide is disclosed, the two layers in combination providing reduced salt passage in reverse osmosis desalination of brackish waters and of seawater.
    Type: Grant
    Filed: September 3, 2020
    Date of Patent: June 27, 2023
    Assignee: NL Chemical Technology, Inc.
    Inventors: John F. Thompson, Lars Kohler, Qun Song, Jane C. Li
  • Water treatment membrane and method of making water treatment membranes
    Patent number: 11383206
    Abstract: A water treatment membrane and method of making water treatment membranes includes an interfacially formed polyamide layer residing upon a microporous support film and having a plurality of graphene oxide quantum dots attached to an outer surface of the polyamide layer. The polyamide layer has a permeate flux and a salt rejection performance. The permeate flux is increased by the presence of the graphene oxide quantum dots attached to the outer surface of the polyamide.
