Abstract:
1. A method for operating an upflow anaerobic reactor for digesting biodegradable matter and collecting biogas produced therefrom, the method comprising: providing an upflow anaerobic reactor for anaerobically digesting biodegradable matter using a bacterial culture, the upflow anaerobic reactor comprising: providing a bacterial culture comprising a sludge layer in the lower portion of the vessel for biodegradation of biodegradable material and production of biogas therefrom; operating the upflow anaerobic reactor so as to create an upflow in the vessel by introducing an influent including biodegradable material into the lower portion of the vessel via the inlet, and withdrawing an effluent from the upper portion of the vessel via the effluent outlet; and operating the auger assembly so as to disrupt solid material contained in the effluent that collects at the fluid-air interface.
