Apr 1, 2024 · Dark fermentation of caw manure was optimized via pre-treatments and co-fermentation. • RSM can be applied to dark fermentation process to optimize the release of carbohydrates. • The pretreatment of H 2 O 2 combined with sonification enhances biohydrogen production. • The co-fermentation of cheese whey and cow manure resulted in higher H
Anaerobic fermentation technology could produce biogas from the organic matters derived from manure by the metabolic activity of microorganisms, and it was recommended as the recycling method for manure treatment in China [3].
Sep 1, 2021 · Co-anaerobic fermentation (co-AF) of swine manure (SM) and apple waste (AW) has been proved to be beneficial for lactic acid (LA) production. In order to further improve the LA production, three important parameters, namely AW in feedstock, temperature, volatile solids (VS) of feedstock, were evaluated using Box-Behnken design and response surface methodology.
Technical Specialist. +31 (0)6 51576194. +31 (0)58 2999 913. vanderveen@jongia.com. Manure Fermentation A guide to enhance biogas production Manure is one of the most abundant agricultural waste products, and it has been used for a long time.
Nov 11, 2022 · Abstract. : 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.
Abstract. Biohydrogen fermentation using liquid swine manure as substrate supplemented with glucose was investigated in this project. Experiments were conducted using a semi-continuously-fed fermenter (8 L in total volume and 4 L in working volume) with varying pHs from 4.7 through 5.9 under controlled temperature (35 ± 1 °C).
Sep 1, 2021 · In order to explore the effects of adding biochar on biogas production by high solid concentration anaerobic fermentation of livestock and poultry manure and agricultural safety, this study used pig manure, cow manure and chicken manure as fermentation raw materials, and carried out experiments on biogas production by mesophilic temperature anaerobic fermentation with high solid concentration.
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
May 5, 2023 · The objective of this work was to determine the potential of chicken manure as a substrate for biogas production after pretreatment. The effects of removing excess nitrogen from chicken manure by water extraction in a temperature range from 20 °C to 60 °C to increase methane production were investigated. The dynamics of the process and efficiency of biogas production were also analyzed. As a
Dec 1, 2020 · The PHBV pilot facility was designed to produce PHBV-rich biomass from dairy manure using the standard three-stage process (fermentation, enrichment, and production; Serafim et al., 2008). As the names imply, the fermenter fermented the dairy manure to produce a VFA-rich substrate.
The solid digestate obtained from the high solid anaerobic digestion through a garage-type dry fermentation system using high-density bundled rice straw and swine manure was a value-added by-product that could be used as growth medium in seeding production.
Apr 19, 2023 · However, factors such as the gradual decoupling of livestock and crop production 6, poor manure treatment technologies 14, they have been published in high-quality academic journals 19,22,23 ...
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 ).
The International Livestock Expo – ILDEX PHILIPPINES 2025 is set to take place from August 27–29 at the SMX Convention Center in Manila, Philippines! Henan Bolong will showcase its core equipment and livestock manure solutions at Booth No. C11.
Traditional manure composting is prone to complaints and environmental fines due to the decomposition of organic matter, uncontrolled fermentation environment and unsealed diffusion.Bolong sealed composting tank blocks odor at the source of the sealed tank and removes odor at the end of the spray tower (with an efficiency of over 95%), combined with high-temperature aerobic fermentation to inhibit odor-producing bacteria, effectively solving the odor problem. Mature manure can be directly used as fertilizer or sold to increase income, suitable for large-scale farms, and can be quickly matured to meet standards in 7 days. The equipment helps farms comply with environmental regulations and avoid penalties, and intelligent control reduces costs and increases efficiency, achieving odor elimination and turning waste into treasure.
