  • Ultrafiltration processes for the recovery of polymeric latices from whitewater
    Patent number: 5342863
    Abstract: Polymer is recovered by ultrafiltration from a whitewater waste stream generated during the production of a polymer latex. The whitewater stream is circulated through an ultrafiltration system in laminar flow, under conditions of shear insufficient to destabilize the whitewater emulsion, and the recovered polymer is in the form of an emulsion which may be blended at significant levels into the original polymer latex without degrading its performance properties.
    Type: Grant
    Filed: July 15, 1992
    Date of Patent: August 30, 1994
    Assignee: Rohm and Haas Company
    Inventors: Randall G. Buckley, George L. Eastburn, Marion C. Schmitz, Barry R. Breslau, Shawn P. Tansey

  • Membrane separation system and method of operation
    Patent number: 4986918
    Abstract: An improved separation system and its method of operation for the separation of solutes, colloidal particles, or suspended matter from solutions of suspensions containing the same is disclosed. In a preferred embodiment, this invention relates to a simple and economic membrane filtration system that can be operated in many of the modes of operation of a membrane filtration system, especially suction backwashing, without mixing the filtrate with the feed stream.
    Type: Grant
    Filed: November 8, 1989
    Date of Patent: January 22, 1991
    Assignee: Romicon Inc.
    Inventors: Barry R. Breslau, John Slegers
  • Series ultrafiltration with pressurized permeate
    Patent number: 4435289
    Abstract: Process and apparatus for providing separation of solutes, colloidal particles or suspended matter by ultrafiltration wherein increased cost efficiency and reduced energy requirements are realized by series flow configuration, utilizing increased operating pressures, and back pressurization of permeate.
    Type: Grant
