Oct 31, 2020 · The physicochemical compositions of cow manure and sheep manure showed that volatile solid (VS) contents were close to each other in manure compositions (77.6% and 64.7%, respectively), while the potential of methane production from cow manure (673.44 mL CH 4 /g VS) was greater than that from sheep manure (320.32 mL CH 4 /g VS).
Apr 1, 2024 · Microbial fermentation, a method commonly utilized in the industry to produce LA, accounts for approximately 90% of LA production. This is largely due to its low production cost, high optical purity, and wide range of substrates (Agrawal and Kumar, 2023). In industrial LA processes, it is generally produced mainly based on starch or sugars.
The selection of livestock manure and crop straws as agricultural waste for this review article is due to high nutrients contents and massive generation of them worldwide. This article also included the development of aerobic fermentation technology and listed the high-temperature fermentation tanks.
Mar 1, 2009 · Biogas production, ammonia concentration, and change in pH through 9 batches of anaerobic fermentation of chicken manure at 37 °C. The amount of total biogas produced, ammonia concentration, and pH values at the end of each batch were not of equal values, and this is attributed to different culture times ( Fig. 1 ).
Feb 1, 2022 · It is used for alcoholic fermentation, solvents, organic acid production, wastewa ter treatment. It involves high-quality effluent through the membranes and elimi nates the sedimentation and
Jun 1, 2007 · In this paper, continuous production of hydrogen through fermentation with liquid swine manure as substrate was researched using a semi-continuously fed fermenter (8 L in total volume and 4 L in
May 2, 2023 · Therefore, high-temperature anaerobic treatment is usually not used in the methane production stage to avoid ammonia inhibition for nitrogen-rich manure, such as chicken manure, duck manure, and pig manure. In addition, thermophilic anaerobic digestion commonly provides a high biogas production rate and benefits pathogen reduction [7,72,73
May 5, 2023 · The aim of this study was to investigate the biogas production performance of an integrated microbial electrolysis cell and anaerobic reactor system (MEC-AR) treating cattle manure at different applied voltages and hydraulic retention times (HRT) ranging from 6 days to 1 day. The MEC-AR system was operated in semi-continuous mode under various voltage applications of 0.3, 0.6, and 1.0 V and
Jan 1, 2020 · Patinvoh et al. [26] designed and developed a horizontal PFR (Fig. 6.2) for continuous DF in Sweden, and studied the efficiency of this fermenter using untreated cattle manure as a substrate. The cattle manure was bedded with straw (TS concentration of 22%), which was obtained from a local cattle farm and used in a continuous digestion process.
May 1, 2024 · The fermentation potential, carbon balance, salt stress variation, microbial succession and membrane filtration were comprehensively analyzed to evaluate the AnMBR performance. The results of this study could make value contribution to robust production of VFAs from high-strength organic wastewater. 2. Materials and 2.1.
May 2, 2022 · Batch experiments were performed to evaluate the biohydrogen and biomethane production by co-digestion of chicken manure and food waste in a two-stage mesophilic fermentation process. Results showed that no hydrogen was produced in the first stage of sole chicken manure fermentation, while methane yield was 247.3 mL·g−1-VS. By comparison, the co-digestion process with food waste proportions
The product/substrate ratio for the fermenter is 18.7 10 3 g H2 per g TVS, i.e., for every 6 L of manure, 9.81 L of pure hydrogen gas can be generated. For efficient hydrogen gas production, the methane content in the fermenter needs to be controlled at <2%.
Jan 1, 2016 · The results showed that maize silage and haulm tomatoes are good co-substrates for fermentation of chicken manure. A mixture consisting of 60% manure, and 40% corn silage characterized by the
Feb 1, 2009 · Swine manure, for example, as sole feedstock for biohydrogen production yields low biohydrogen volumes by fermentation at both mesophilic (between 30 and 40 °C) (Wagner et al. 2009) and
Nov 11, 2022 · Acidogenic fermentation of chicken manure (CM) for production and recovery of volatile fatty acids (VFA) is an interesting biological waste-to-value approach compared to benchmark organic waste management strategies.
