(Li et al., 2011). Though the solid-state AD process has attracted increased attention all around the world because of its reduced cost in digesters and slurry handling, the process sometimes suffers from inhibition problems (Liu et al., 2006) and is harder to control. First, the solid-...
Each digester is separately controlled to provide the best process conditions for the respective bacterial group. Digester disruption can occur due to poor substrate composition, accidental inclusion of toxic substrates, improper loading rate, or various other process parameters. Advanced digester technology...
The results of the environmental analysis show that considerable electricity generation and greenhouse gas emissions reductions are possible, depending primarily on feedstock availability and proximity to the centralized anaerobic digester.;The initial results are encouraging and future work is warranted for ...
“bins,” and frequent transport of the waste to the anaerobic digester has to be performed by local farmers. Even if the complete system seems to be difficult to implement in other cases, it adds an interesting social aspect to the valorization process with the involvement of inhabitants. ...
The composition of biogas varies with the type of feedstock used in the process and the operating conditions of the digester. In general, biogas consists of 50–75% methane (CH4) and 25–50% carbon dioxide (CO2) with small amounts of water vapor (H2O), hydrogen sulfide (H2S), and ammon...
A growing interest in alternative energy and specifically, biogas and anaerobic digestion, is fuelling the construction of biogas digester facilities, which typically produce methane gas through bacteria-based anaerobic digestion (fermentation) of animal
The trade-offs in maintaining optimum digester temperatures to maximize gas production while minimizing expenses are somewhat complex. Studies on digesters in the north-central areas of the country indicate that maximum net biogas production can occur in digesters maintained at temperatures as low as ...
Finally, the presence of sodium for marine species can also affect the digester performance. Physico-chemical pretreatment, co-digestion, or control of gross composition are strategies that can significantly and efficiently increase the conversion yield of the algal organic matter into methane. When ...
Below is given the brief procedural description of the testing of the digester under investigation experimentally. The period of experimentation can be divided into four Methodologies for substrate analysis The successful operation of anaerobic biotechnology for waste treatment depends upon the composition ...
