  • Biological waste water purification reactor and method
    Patent number: 10308535
    Abstract: A biological reactor for treating wastewater. The reactor includes a gas injection system and a system for directing wastewater into the reactor. Further, the reactor includes a biological filter comprised of a packed bed of biofilm carriers and a volume of moveable biofilm carriers. During the method of treating the wastewater, the wastewater moves upwardly through the reactor and through the biological filter while gas is emitted from the gas injection system.
    Type: Grant

  • Method for treating an effluent using simultaneous nitrification/denitrification in a biological filter
    Patent number: 6632365
    Abstract: The invention concerns a method and installation for the treatment of excess sludge derived from biological wastewater treatment plants. The method is characterized in that it consists of associating at least one digestion step (4) and at least one wet oxidation step (2) of said sludge, said wet oxidation step being conducted at a temperature of between 50° C. and 180° C. and at a pressure of between 2 and 40 bar.
