The Design of Anaerobic Digesters
1981Anaerobic digestion is a biological process which can be used for the treatment of natural organic wastes and the production of methane gas. Most of the problems associated with anaerobic digesters are of a practical nature, many of them due to poor basic design.

Use of biochars in anaerobic digestion
Bioresource Technology, 2014This study investigated the behavior of biochars from pyrolysis (pyrochar) and hydrothermal carbonization (hydrochar) in anaerobic digestion regarding their degradability and their effects on biogas production and ammonia inhibition. A batch fermentation experiment (42°C, 63 days) was conducted in 100mL syringes filled with 30 g inoculum, 2g biochar ...

The Microbiology of Anaerobic Digestion [PDF]
, 1986 The combined and coordinated metabolic activity of an anaerobic reactor population is required for the complete degradation of complex organic matter to CO2 and CH4. The intermediates necessary for certain microorganisms are produced as a consequence of the action of others and therefore consortia of bacteria are frequently involved in these ...

Biotechnology and Bioengineering, 1974
AbstractThe mixing of the anaerobic digester contents significantly influences the efficiency of this operation; in particular, hydraulic dead zones are extremely detrimental to the reaction kinetics involved in anaerobic digestion. An analysis of the relative importance of thermal fluid movement in the digester to those caused by fluid inflow and ...

Anaerobic Digestion in Portugal
1986In this short presentation, the present situation relating to existing or under construction plants as well as research and development (R&D) endeavors are briefly outlined. Several anaerobic digestion plants are used in conjunction with domestic wastewater treatment and industrial wastes, but agricultural wastes have not received any similar attention.
