2023/7/28/ · Anaerobic fermentation (AF) can effectively dispose of kitchen waste (KW) without the shortcomings of traditional such as incineration and sanitary landfill. However, KW has a high organic content, which easily leads to acidification and ammonia inhibition during digestion. To mitigate this issue, anaerobic co-digestion (AnCoD) with
2023/2/1/ · The inoculum used for fermentation stage was taken from a semi-continuous mesophilic anaerobic fermenter using WAS as substrate, 170 mmol/L ethanol as ED, and 0.05 M 2-bromoethanesulfonate as methanogens inhibitor (Wu et al., 2021). The fermenter was maintained at 35°C, with a sludge retention time of 15 days. 2.2. WAS pretreatment with Fe
Abstract. The complexity and high cost to separate and recover short chain fatty acids (SCFAs), ammonium ions, and phosphates in the sludge fermentation liquid hinder the application of sludge anaerobic fermentation. In this study, an interesting phenomenon was found in a sludge anaerobic fermenter with a dynamic membrane (DM) which could not
2024/5/1/ · 2.2. Semi-continuous operation of AnDMBR for sludge anaerobic fermentation. A schematic diagram and the operational mode of the AnDMBR and the properties of the DM are provided in the Supplementary Material.In stage 1, the sludge anaerobic fermenter was operated without DM, and 600 mL of pretreated sludge
2018/7/2/ · Fermentation allows food to retain more vitamins and minerals than other types of preserving. The pressing plate keeps the kimchi/pickles in an airtight space
2023/4/14/ · The scale-up technology of anaerobic fermentation stirring equipment is worthy of attention. Computational fluid dynamics (CFD) simulations were used to study the scale-up of anaerobic fermentation mixing under different solid content conditions. The applicability of different scale-up criteria was analyzed by investigating the relative
2024/4/23/ · In 2021, Luxembourg's primary energy production from other biogases from anaerobic fermentation amounted to 15.5 kilotons of oil equivalent. In the period of consideration, figures peaked in 2018
Metabolism without Oxygen: Fermentation In aerobic respiration, the final electron acceptor for the electron transport chain is an oxygen molecule, O 2.If aerobic respiration occurs, then approximately 30 molecules of ATP will be produced during the electron transport chain and chemiosmosis using the energy of the high-energy electrons carried by NADH or FADH 2 to
2024/2/25/ · Acidogenic fermentation can convert food waste (FW) into small molecules of acids and alcohols, and the broth can be used as a carbon source of denitrification in wastewater treatment plants. However, the soluble nitrogen-containing substances generated in fermentation influence the quality of the carbon source, and microbial nitrogen

2021/5/12/ · Also, many strict or facultative anaerobic micro-organisms may be involved in anaerobic digestion for hydrogen production, such as bacteria of the genus Clostridium, Desulfovibrio, Thermotoga, etc. . Wang & Zhao studied two-stage dark fermentation using food waste employing indigenous food waste microflora for hydrogen production . Their
2023/8/3/ · Stirrer glands and bearings. The most important factor of designing a fermenter is to maintain aseptic conditions inside the vessel. It is highly challenging in the case of pilot-scale fermenters. Therefore stirrer shafts are required. These stirrer shafts play an important role to seal the openings of a bioreactor.
2022/12/1/ · The anaerobic fermentation was carried out in a 250 ml reactor. In each reactor 150.0 ml of pretreated WAS as substrate and 23.2 ml of seed sludge were added. A gas bag of 1 L was connected to each bottle to collect biogas during the experiment. The pH of mixture in each reactor was adjusted to 7.0 by using 1 mol/L hydrochloric acid and 1 mol/L
