  • Process and apparatus for treating biosolids from wastewater treatment
    Patent number: 6719903
    Abstract: A process and apparatus for treating biosolids from biological wastewater treatment. The temperature of autothermal aerobic treatment of biosolids is controlled by sensing the oxidation/reduction potential of the solution and adjusting the amount of oxygen or biosolids supplied to the solution through a jet aerator (1) having a liquid header (3) for the recirculation of the solution and an air header (5).
    Type: Grant
    Filed: April 30, 2001
    Date of Patent: April 13, 2004
    Assignee: Thermal Process Systems, LLC
    Inventors: Richard L. Pressley, Jeffrey D. Williamson
  • Process for controlling foam in a treatment reactor
    Patent number: 6514411
    Abstract: The invention relates generally to a process and apparatus for treating biosolids resulting from the treatment of biological wastewater streams. The invention relates to autothermal aerobic treatment of biosolids where temperature is controlled by adjusting the amount of shear generated through jet aeration devices. The invention provides for a truly aerobic environment under which thermophilic microorganisms will thrive. The invention also relates to a method and apparatus for controlling foam generated in a treatment reactor.
