2021/9/1/ · Adding 5 g/L of bentonite effectively reduced the genes of ermB, ermF, tetQ, tetX, sul1, sul2 and intI1 with a range of 80.82% - 100.00% in biogas residue under mesophilic reactor. The abundance of ARGs and intI1 in biogas residue were lower than in slurry under both temperatures with 5 g/L of bentonite. Statistical analysis indicated that
2018/8/1/ · Dissolved organic matter (DOM) extracted from composting of biogas residue was characterized using spectroscopic techniques. Spectral parameters, specific UV absorbance at 254 (SUVA 254), ratios of spectral slopes (S R), and humification index (HIX) were used to assess the structural characteristics of the DOM.During composting,
2019/2/15/ · The emission rates of NH 3 gas (ppm) and CO 2 (%) from compost reactor treatment mixtures were measured using the detector tubes (DT) method and a portable biogas analyser (GA5000, Geotech, UK), respectively. Samples were analyzed for pH, EC, C:N ratio (from TC and TN), total potassium (TK), and heavy metals for initial
2024/1/5/ · The H 2 S and CO 2 as the other components of biogas produced from each anaerobic reactors were removed by movement the biogas from a container with alkaline solution (3 M NaOH).
This study used biogas residue produced by anaerobic fermentation of food waste as the raw material in large-scale windrow composting. and nutrient parameters, using structural equation modeling (SEM). Results showed that the temperature of T2 compost with the microbial consortium increased more rapidly. The pH ranges of T1 (without the ...

2022/12/1/ · 1. Introduction. Straw with lignocellulose as the main component is considered to be a suitable feed stock for biofuels and bio-products [1].In recent years, methane fermentation technology is one of the most promising bio-energy production technologies because of its high energy output/input ratio (28.8 MJ/MJ) [2].Although
2022/12/1/ · The resource usage of biogas residue may be realized by composting and biochar generation of biogas residue, however there are certain issues. For example, biogas residue has a high moisture content, and pyrolysis of biogas residue to make biochar needs a lot of energy, limiting energy recovery and wasting non-renewable
2024/4/3/ · The impact of biogas residual biochar (BRB) on the humification and carbon balance process of co-composting of hog slurry (HGS) and wheat straw (WTS) was examined. The 50-day humification process was significantly enhanced by the addition of BRB, particular of 5% BRB, as indicated by the relatively higher humic acid content
Composted biogas residue and spent mushroom substrate as a . Sep 1, 2017 · Demir [85] showed that a mixture of 70% spent mushroom compost +30% perlite as well as only aged spent mushroom compost are both effective for widening seedling growth parameter of Charleston . Utilization of Aerobic Compression Composting Technology on
2021/5/1/ · The biogas residue was from the digestate of pig manure. The biogas station operated normally, using a continuous stirred tank reactor (CSTR) to digest the pig manure anaerobically. The total tank volume was 400 m 3 , the digestion temperature was approximately 35 ± 2 ℃, and the hydraulic retention time was about 20 days.
2019/10/28/ · Biogas plants as a renewable energy technology for generating energy also produce biogas residue. The biogas residue, which is a sustainable source, has a rich mineral content and a wide
