Sep 15, 2023 · The effective conversion and recycling of organic solid waste contribute to the resolution of widespread issues such as global environmental pollution, energy scarcity and resource depletion. The anaerobic fermentation technology provides for the effective treatment of organic solid waste and the generation of various products.
Nov 22, 2013 · Food waste was collected from the food center of Khon Kaen University campus, Khon Kaen, Thailand. It was mainly made up of rice, vegetables, fruits and meats. Bones were removed from the food waste before being mixed with tap water at the volumetric ratio of 1:3 and then grinded in a food blender. The pH of the resulting food waste slurry was 7.2.
A pilot-scale two-phase hydrogen/methane fermentation system for food waste was operated at HRT 21 h with a peak hydrogen yield of 1.82 H 2 mol/mol glucose. Over 80 % of the methane was produced in the methane fermentation tank with acetic acid as the dominant organic acid.
Oct 1, 2021 · During food waste fermentation, the addition of biogas slurry promoted the production of lactic acid because it increased the pH values, maintained low OPR, prompted microbial diversity, and enriched functional microorganisms. A proper dose of industrial biogas slurry can increase the lactic acid yield to 0.42 g/g VS added. This result provides
There are four treatment procedure of the organic fertilizer fermentation tank. Firstly,automatically feeding.Then,you can make material get perfect stage through high-temperature fermentation. After that,material is discharged from your fermenter. Finally,you can put these fermented material into storage. organic tertilizer production tank.
Fermentation tank is a kind of organic compost making machine, which is used for aerobic composting of organic waste. As we all know, the process of organic waste fermentation includes ventilation, temperature control, turning of compost pile, water content control, harmless control and thorough fermentation of organic waste.
Jan 1, 2022 · 1. Introduction. Anaerobic digestion (AD) is practiced extensively for treatment of biodegradable waste for biomethane generation (Caposciutti et al., 2020).This technology has capability of managing organic waste such as food waste, lignocellulosic biomass and residues, energy crops and organic fraction of municipal solid waste (Ardolino et al., 2018).
Due to the high demand for food and meat for the world's growing population, the agricultural sector is expanding every year. Timely and effective treatment is of utmost importance to utilize organic matter in agricultural waste and avoid environmental pollution. Composting or aerobic fermentation is an effective way to treat agricultural waste and produce organic fertilizer. Improving the
Mar 1, 2024 · Organic waste contains a large amount of matter containing carbon, so it is feasible to use it as substrate or electron donor to produce medium chain fatty acids, such as in a fermentation broth of organic waste such as sludge, food waste, fruit and vegetable waste, etc (Reddy et al., 2020; Wang et al., 2020a, Wang et al., 2020b, Wang et al
Dec 28, 2015 · It consisted of one 2.3 L reactor with a working volume of 1.7 L. Food waste was added with a peristaltic pump (Cole Parmer System 7553-12) from a storage tank at 4 °C (avoiding a fermentation of OSW in the storage tank). The pH in the reactor was adjusted by an automatic pH controller (Black Stone BL931700). It was coupled to a low flow
Mar 26, 2021 · The application of solid-state fermentation by different microorganisms (fungi, yeasts, bacteria) to produce several value-added products was analyzed, focusing on the exploitation of lactic acid bacteria as workhorses for the production of flavoring compounds. Keywords: waste, valorization, fermentation, lactic acid bacteria, flavor.
Dec 12, 2022 · Solid-state fermentation (SSF) is part of the pathway to consolidate waste as a relevant alternative for the valorization of organic waste. The objective of SSF is to produce one or several bioproducts of added value from solid substrates. Solid-state fermentation can use a wide variety of organic waste as substrates thus, it is an excellent candidate in the framework of the circular
Product Application of Fermentation Tank . Organic Waste Fermentation Tank can be used to deal with pig manure and chicken manure, cow dung, sheep dung, the fungus mushroom residue, medical, crop straw and other organic waste, 10 hours to complete disposal process, covers an area of less , no pollution , eggs thoroughly to kill disease, is the
Apr 2, 2024 · During fermentation, microorganisms present in the organic waste break down the materials, transforming them into nutrient-rich organic fertilizers. The waste gas generated during this process is treated by the waste gas treatment system within the tank to eliminate odors and harmful emissions.
The waste volume is reduced by more than 90% in 24 hours by the enhancement of biodegradation and evaporation processes. For treatment, organic waste and wood chips are combined in the fermentation tank (the wood chips are used as carriers). Organic waste and wood chips are agitated with air to activate the existing microbes in the tank.
