Anaerobic Digester, Biogas Engineering, CHP Systems, Waste to Energy and Waste to Fuel Project Development Services
To produce data for the training of the neural nets an anaerobic digester was operated at steady state and disturbed by pulsing the organic loading rate. Measured parameters were: gas composition, gas production rate, volatile fatty acid concentration, pH, redox potential, volatile suspended solids ...
In the case of a wastewater collection system connected to an anaerobic unit, as in Flintenbreite, the storage unit built in situ has two objectives: a buffer zone as pretreatment for the organic matter and a tank to modulate the inputs going to the digester [59,60]. In the Nashik proj...
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 ...
Many industries use AD digesters to manage industrial waste more efficiently with added energy incentives. Although current biogas applications focus on energy production, various biogas-derived value-added chemicals are expanding their economic and environmental potential. This chapter describes the ...
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 ...
( nordmann, 1977 ; logan et al., 2019 ). in this study the operation of lab-scale mesophilic and thermophilic anaerobic digesters fed with a mixture of solid and liquid whiskey distillery by-products were investigated for biogas production. this collaborative study between industry and academia ...
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...
of the stages and the process, the activities of several microorganisms that inhibit the process can be avoided. Gicon digester is operated without inoculation and works with the recirculation of percolate (André et al., 2018). Hydrolysis and acidogenesis taking place in the external digester ...
receive the liquid suspension of solid waste, said anaerobic digester chamber comprising:a floor, walls, and a ceiling;a digester chamber outlet wherein a suspension of digested waste solids exit the digester; andone or more gas collection ports to collect gas produced in the anaerobic digester....
