Cleaning biogas with bacteria
Organic materials added to an anaerobic digester commonly contain sulphur components. During the anaerobic digestion process, the sulphur is converted into hydrogen sulphide (H2S), which is absorbed by the biogas. When the biogas produced in an AD plant goes on to be combusted in a gas engine or boiler, the H2S will give off sulphur dioxide (SO2) and sulphuric acid (H2SO4). It is for this reason ...

Aerobic thermophilic bacteria enhance biogas production
The enhancing effect of aerobic thermophilic (AT) bacteria on the production of biogas from anaerobically digested sewage sludge (methanogenic sludge) was investigated. Sewage sludge (5%, w/w) was incubated at 65°C with shaking for a few months to prepare the AT seed sludge. AT sludge was prepared by incubation of the AT seed sludge (5%, v/v) and sewage sludge (5%, w/w) at 65°C with shaking. The ...

Biogas and Anaerobic Digestion in Relation to CH4 Methane Monitoring
The use of biogas as a renewable energy source currently accounts for 10 % of global primary energy consumption1 and is often heralded as the perfect example of the ‘circular economy’ – where waste products can be reused to generate energy for other processes in a self-perpetuating cycle.2Biogas consists of the mixture of gases produced by the breakdown of organic matter by bacteria under ...

New technology enables biogas plant optimization
Governments around the world are seeking to lower greenhouse gas (GHG) emissions in the fight against climate change, to reduce waste to landfill, and to increase their utilisation of renewable energy in compliance with international agreements. Consequently, in many countries, subsidies have been made available to encourage the growth of the biogas sector. According to the International ...
