2014/3/1/ · The anaerobic digesters were maintained at 37 ± 1 °C in a temperature-controlled chamber. Assays with inoculum alone were also used as control samples. Pig manure as a kind of good organic materials, assuming the first-order kinetics can be used to describe the process of methane fermentation of pig manure. The cumulative methane ...
2014/3/1/ · 1. Introduction. During the manufacturing of cane sugar, a large amount of molasses is produced. Sugar refineries typically use molasses to produce alcohol, and for 1 ton of alcohol produced, 13–15 tons of wastewater (i.e., MAW) are typically generated.MAW contains approximately 88% molasses (Jain et al., 2002), and its components vary with
2023/7/25/ · 5 kg of pig manure was mixed with Sitka spruce sawdust at the ratio of 4 (manure):1 (sawdust) (w/w) and placed in a bucket. Sawdust was obtained from the local hardware store.
2022/11/21/ · Fermented organic fertilizers made from pig manure contaminated with antibiotics are widely used in fruit tree production. However, their effects on the residual antibiotics and the spread of antibiotic resistance genes (ARGs) and mobile genetic elements (MGEs) in apple orchards are still largely unknown. In the present study, we
2016/11/15/ · Single chamber microbial fuel cells for high strength wastewater and blackwater treatment—A comparison of idealized wastewater, synthetic human blackwater, and diluted pig manure pre-fermentation of a substrate can increase power densities and improve MFC performance [5]. The Chemical Oxygen Demand (COD) is a parameter
2023/12/1/ · The specifics of the fermentation process of livestock manure remain unclear, and the influence of alkaline pH on the fermentation of various manures is yet to be fully explored. In addition to its direct impact on anaerobic digestion, alkaline pH significantly influences downstream processing and post-AD applications.
2022/3/16/ · The methodology was applied to justify the best suitable processing technology for a large-scale pig farm in the Leningrad Region with 17,800 heads of pigs and 54,750 t of pig manure per year.
In this study, pig manure rich in phosphorus was used as the recovery object, In order to realize the maximum recovery of phosphorus resources in pig manure, this study established a phosphorus recovery route combining the electrochemical method with the Vivianite method using sacrificial iron anode. And in order to obtain phosphorus rich
2023/5/2/ · Anaerobic digestion of animal manure results in the production of renewable energy (biogas) and nutrient-rich biofertilizer. A further benefit of the technology is decreased greenhouse gas emissions that otherwise occur during manure storage. Since animal manure makes anaerobic digestion cost-efficient and further advance the
2023/9/26/ · The main research content is to take pig manure as the object, conduct anaerobic fermentation through pH adjustment to obtain P-rich supernatant, and then
2015/4/1/ · Wet fermentation of swine manure became the focus of previous researches because of less ammonia inhibition, whereas dry fermentation gained less attention. Nevertheless, biogas production from separated pig slurry solids is more profitable than using untreated raw slurry because there is a higher CH 4 potential per unit fresh
2024/2/1/ · Each anaerobic digestion chamber had a working volume of 860 m 3, Application of anaerobic digestion model No. 1 for simulating fermentation of maize silage, pig manure, cattle manure and digestate in the full-scale biogas plant.

2024/1/22/ · The experiment was set up using pots with volumes of 10 L, replicating the storage conditions on farms. The matrices (i.e., digestate, manure, and slurry) were collected from three different farms as follows: digestate from a conventional pig breeding farm, slurries from an organic pig breeding farm, and manure from an organic cow …
The fermentation supernatant was treated in a two-chamber 23 electrolytic tank, and more than 90% of P was recovered, and 84.66% purity of vivianite was obtained. 24
