TLDR
The comparative results of the reactor performance at steady state clearly showed the superior performance of the thermophilic non-mixed reactor with respect to lower VFA, higher gas production and volatile solids removal implying that microbial consortia proximity can alleviate the problem of poor effluent quality in thermophobic system.About:

Journal ArticleDOI
Optimisation of the anaerobic digestion of agricultural resources.
TL;DR: Current optimisation techniques associated with anaerobic digestion are reviewed and possible areas where improvements could be made are suggested, including the basic design considerations of a single or multi-stage reactor configuration, the type, power and duration of the mixing regime and the retention of active microbial biomass within the reactor.

Macroscopic mass and energy balance of a pilot plant anaerobic bioreactor operated under thermophilic conditions.
Teodoro Espinosa-Solares,John Bombardiere,Mark Chatfield,Max Domaschko,Michael Easter,David A. Stafford,Saul Castillo-Angeles,Nehemias Castellanos-Hernandez +7 more
TL;DR: Results suggest some changes to the pilot plant configuration are necessary to reduce power consumption although maximizing biodigester performance, and a modification of the typical continuous stirred tank reactor is a promising process being relatively stable and owing to its capability to manage considerable amounts of residuals at low operational cost.

Journal ArticleDOI
Effects of hydrogen and formate on the degradation of propionate and butyrate in thermophilic granules from an upflow anaerobic sludge blanket reactor.
TL;DR: No significant differences in the stimulation of the degradation rates were observed when the disintegrated granules were supplied with methanogens that utilized hydrogen only or hydrogen and formate, indicating that interspecies formate transfer was not important for stimulation of propionate and butyrate degradation.
