The test engine was instrumented to measure torque, rpm, temperatures and pressures, flow rates of gases and exhaust gas composition. The impact of digester gas and exhaust gas recirculation on NOx emissions was measured with a chemiluminescent analyzer. For some runs the non-methane organic gases...
The book gives a fair introduction to the microbiology and ecology of the anaerobic fermentation process, to the composition of animal waste, and to digester design. However, the calculations are too often poor, incomplete, or incorrect, and the treatment of digester design and operation is ...
The biotic factors cover increased abundance of hydrophobic, filamentous micro- organisms that can interact with, and stabilize, gas bubbles in the foam71,73. To gain further insight into potential foam forming microbes, we examined the global diversity of known filamentous bacteria in ADs (Fig. ...
biogas can be further used for cooking and for electricity generation, which can be processed throughgas engines. The fully stabilizedsludgethat remains afteranaerobic digestioncan be further used as asoil conditioner. Depending on the composition of the input waste it can even be sold as compost....
Biogas composition, including methane, carbon dioxide, oxygen, and hydrogen sulfide, was determined weekly during continuous operation of the digesters, using a portable gas analyzer (Biogas Check, Geotech, Chelmsford, UK). The TS and VS content of the effluent were measured once a week according...

Aims: To identify the bacterial and archaeal composition in a mesophilic biogas digester treating pig manure and to compare the consistency of two 16S rDNA... Zhou, ZH (reprint author), Chinese Acad Sci, Shanghai Inst Biol Sci, Inst Plant Physiol & Ecol, Key Lab Synthet Biol, Fenglin Rd...
A mean gas yield of 0·215 m 3/kg VS added was obtained with a mean gas composition of 62·6% methane, together with a mean volatile solids reduction of 31% and cellulose reduction of 57%. To improve the efficiency of the process, a digester containing fresh solid material (C) was ...
It can maintain the pressure of 5kPa, and can also be combined with the integrated double membrane biogas holder to make fermentation gas production and storage integration device.Note: For each assembled tank, it's customized design to accommodate the client's wishes and external factors. ...
Natural gas, or methane, is a fossil fuel - was created hundreds of thousands of years ago by the anaerobic decomposition of organic materials (primarily algae). It is often found in association with oil and coal.The same types of anaerobic bacteria that produce natural gas also produce ...
