v. t. e. Biogas is a gaseous renewable energy source [1] produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste, wastewater, and food waste. Biogas is produced by anaerobic digestion with anaerobic organisms or methanogens inside an anaerobic digester, biodigester or a bioreactor. [2]
2021/9/1/ · The fermentation products of M0, M3, M5, T0, T3 and T5 were divided into two parts consisting of biogas slurry (S) and residue (R). Eleven targeted ARGs including Tetracyclic antibiotics: tetQ, tetX, tetM, tetW, tetO, Macrolide antibiotics: ermB, ermF, mefA, Sulfanilamide antibiotics: sul1, sul2 and the class 1 integron-integrase gene (intI1) in
2024/1/1/ · The remediation plant (Pennisetum hybrid) and anaerobic fermentation residues (biogas slurry and biogas residue) were provided by Ganzhou Ruiyuan Biotechnology Co., Ltd. in Jiangxi Province (China), which had a large-scale biogas project (20,000 m 3) for the centralization treatment of animal manures from 34 large-scale farms
2017/5/1/ · Afterwards, these materials were blended in proportions of 1:1, 1.8:1, 2.8:1, and 3.8:1 based on their dry mass. The biogas slurry (water content of 84.1%) from final-stage fermentation, taken from a normal biogas digester used in the poultry feeding industry in the Central China Economic District, was used as the inoculation.
This study used biogas residue produced by anaerobic fermentation of food waste as the raw material in large-scale windrow composting. The effects of the addition of a microbial consortium on the physical and chemical properties and stability of composting of biogas residue were studied. The maturit
2024/3/14/ · Anaerobic digestion is a potential treatment for industrial wastewater that provides valuable end-products, including renewable energy (biogas). However, waste streams may be too variable, too dilute at high volumes, or missing key components for stable digestion; all factors that increase costs and operational difficulty, making
2023/9/5/ · Increased biogas residue related to the rapid development of anaerobic fermentation has become an urgent environmental problem. The pyrolysis of biogas residue into biochar is one of the most promising treatments. In this study, biochar derived from biogas residue was prepared, and the degradation efficiency of phenol by
Dry Fermentation Unit, Find Details and Price about Dry Fermentation Unit Dry Fermentation from Dry Fermentation Unit - Mingshuo Environment Technology Group Co., Ltd.
Biogas fermentation residue could also increase the amount of soil microorganisms. The microbial biomass-C and biomass-N were 59.44% and 56.06% higher than the control, respectively. It was suggested that biogas fermentation residue application could bring better economic and environmental benefits for Z. jujuba cultivation, and also, provide a
2020/10/1/ · For example, cephalosporin C fermentation residue can be converted into biogas, while the biogas and methane yields reached 290 and 200 mL/gTS, respectively [6]. However, the residual antibiotic (erythromycin in this study) unavoidably presents the inhibition effects against the microorganisms and even an ecological risk.
2019/5/25/ · Influenced by feedstock type and microbial inoculum, different microbial groups must precisely interact for high‐quality biogas yields. As a first approach for optimization, this study aimed to identify through time the biogas‐producing microbial community in a 10‐ton dry anaerobic digester treating cattle manure by denaturing
2022/6/17/ · In this study, biochar derived from biogas residue was prepared, and the degradation efficiency of phenol by permanganate (KMnO 4 ) increased from 25.3% to 73.4% in 60 min in the presence of
2021/7/14/ · Biogas and biohydrogen are compatible gaseous biofuels that can be blended with natural gas for reticulated fuel supply to reduce greenhouse gas emissions. Sustainably grown woody biomass is emerging as a potential feedstock in the production of biofuels. Woody biomass is widely available, uses non-arable land for plantation, does not
2022/3/1/ · The average long-term biogas yield of the biogas station under investigation is 130.5 m 3 t −1 which (related to dry weight of feedstock and after conversion to CH4 at 0 °C and 101.3 Pa) is 5% lower than reported by Samarappuli and Berti (2018) and some 6% lower than reviewed by Böjti et al. (2017). The reason may be that the …
