  • Process for mild heat treatment of a flowable fluid
    Patent number: 4938856
    Abstract: A process is provided for sterilizing or pasturizing aqueous fluids by reducing the pH of a fluid in a first compartment of an electrolytic cell, maintaining the fluid with the reduced pH at a sterilizing temperature for a sufficient time to reduce the concentration of microbial cells in the fluid. The pH sterilized fluid is restored in a second compartment of an electrolytic cell.
    Type: Grant
    Filed: March 1, 1989
    Date of Patent: July 3, 1990
    Assignee: FMC Corporation
    Inventor: Stratos E. Hatzidimitriu
  • Process for adjusting the pH of an aqueous flowable fluid
    Patent number: 4936962
    Abstract: A process is provided to adjust the acidity of a flowable fluid by the electrodialysis in a cell containing membrane pairs comprising a bipolar membrane and an ion selective membrane.
    Type: Grant
    Filed: March 1, 1989
    Date of Patent: June 26, 1990
    Assignee: FMC Corporation
    Inventor: Stratos E. Hatzidimitriu
  • Process for mild heat treatment of concentrated fluids from membranes
    Patent number: 4880647
    Abstract: A process is provided for reducing the concentration of microbial cells in a flowable fluid by dividing the fluid into a sterile permeate and a retentate reducing the pH of the retentate in an electrolytic cell, heating the retentate to reduce the concentration of microbial cells therein and increasing the pH of the permeate in an electrolytic cell and combining the retentate and permeate.
