  • PSYCHROPHILIC ANAEROBIC DIGESTION OF AMMONIA-RICH WASTE
    Publication number: 20160297699
    Abstract: The present description relates to a process for the psychrophilic anaerobic digestion of ammonia-rich waste, such as farm manure or municipal waste, comprising the steps of contacting the ammonia-rich waste to an inoculum comprising anaerobic bacteria in a digester and reacting the ammonia-rich waste with the inoculum at a temperature below 25° C. to allow digestion of the ammonia-rich waste.
    Type: Application

    Applicant: HER MAJESTY THE QUEEN IN RIGHT OF CANADA, AS REPRESENTED BY THE MINISTER OF AGRICULTURE AND
    Inventor: Daniel I. MASSÉ
  • PSYCHROPHILIC ANAEROBIC DIGESTION OF HIGH SOLIDS CONTENT
    Publication number: 20160297700
    Abstract: The present description relates to a process for the psychrophilic anaerobic digestion of high organic solids content waste, such as farm manure or municipal waste, comprising the steps of contacting the high organic solids content waste to an inoculum comprising anaerobic bacteria in a digester and reacting the high organic solids content waste with the inoculum at a temperature below 25° C. to allow digestion of the high organic solids content waste.

  • Biological oxidation of hydrogen sulphide in a psychrophilic anaerobic digestion bioreactor subjected to microaerobic conditions
    Patent number: 8496906
    Abstract: A biological process for removing hydrogen sulphide from biogas is disclosed. The process involves injecting a small quantity of air into the gas phase or the liquid phase of a psychrophilic bioreactor to allow microbial flora to convert the hydrogen sulphide into elemental sulphur.
    Type: Grant
