Demand-driven biogas production in anaerobic filters

2. Production of Biogas by Anaerobic Digestion

Anaerobic digestion is a natural process in which bacteria convert organic materials into biogas. It occurs in marshes and wetlands, and in the digestive tract of ruminants. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas can be collected and used as a potential energy resource. The process occurs in an an...

A manometric method for monitoring biogas production in anaerobic bioreactors

Errors are usually made in the quantification of biogas from lab scale anaerobic digestion experiments. This paper deals with the application of a manometric transducer associated with a pressure feedback control system to the estimation of the biogas produced from an anaerobic fermentation of primary sludge. The estimation procedure is reliable and convenient for on-line monitoring of gas prod...

Anaerobic Degradation of Halophyte Biomass for Biogas Production

Anaerobic degradation of wild halophytes (Kalidium caspicum, Salicornia europaea and Climacoptera lanata) from solonchaks of Kyzylkum desert in comparison with conventional glycophyte Panicum coloratum was studied. Lab-scale reactors were fed with dried and milled plant biomass. Tests were operated under batch and continuous mode at mesophilic (M) and thermophilic (T) temperatures. High concent...

Anaerobic Treatment and Biogas Production from Organic Waste

Organic wastes under consideration are of natural origin that possess biochemical characteristics ensuring rapid microbial decomposition at relatively normal operating conditions. When considering the organic waste treatment we have generally in mind organic mineralization, biological stabilisation and detoxification of pollutants. Most common organic wastes contain compounds that are mainly we...
