increase the energy efficiency of manure management. It also reduces the cost of additional water and the operational cost needed for dilution. Dilution reduces the net energy efficiency of manure treatment [14]. A HSAD system can process more manure per unit volume than a conventional low solids anaerobic digestion system.
Apr 29, 2023 · The usage of anaerobic technology converts the manure or organic waste into energy to stabilize the economic status of the country (Glivin et al. 2021). The economic feasibility of anaerobic digestion technology is that it uses the pre-treatment techniques for the production of biogas and ethanol.
Sep 15, 2021 · They obtained a high concentration index of 4.0 and a concentration efficiency of 98.5% with energy consumption of 10.3 kWh m −3. In a similar study, the energy usage of 23.3 kWh m −3 was reported in the integrated system for treating orange juice and coffee ( Rodriguez et al., 2011 ).
Jan 2, 2024 · One hundred fifty tons of liquid manure was fermented in a liquid manure tank by an air ring blower at 0.03–0.045 m 3-air/min·m 3, and 14 t of solid manure was fermented in a solid manure
Jan 6, 2022 · The aim of the study is to draw attention to the fact that reducing methane and nitrous oxide emissions as a result of traditional manure storage for several months in a pile is not only a non-ecological solution, but also unprofitable. A solution that combines both aspects—environmental and financial—is the use of manure as a substrate for a biogas plant, but immediately—directly after
Jul 1, 2021 · The systems present the consumption of electrical energy concerning the total electrical energy produced: (i) consumptions of 10.7% and 9.4% of the electricity generated in mono-digestion systems of cattle manure, for electricity generation powers of 100 and 1000 kWe, respectively; (ii) consumptions of 6.8% and 5.8% of the electricity generated
Jan 28, 2016 · Horse manure that consists primarily of shavings, pellets, sawdust, other woody materials, or peat moss, is much more conducive for renewable energy production. This type of manure has a lower ash content, a higher ash-melting temperature and higher energy content, making renewable energy production easier, cheaper and therefore more
Mar 16, 2022 · Abstract. The current trend towards larger pig farms increases their profitability but might harm animal welfare and the environment. More efficient pig manure management is a way to address this challenge. Available manure handling and utilisation systems may feature from 8 to 50% nutrient loss to the environment.
2019/8/6/ · Fermented foliar fertilizers, FFF (also known as fermented leaf fertilizers, FLF), describe anaerobically digested animal and plant residues used as organic foliar fertilizers.
The vertical fermentation tank is a highly efficient and adaptable piece of equipment developed for the processing of organic waste materials such as animal and poultry manure and sludge. This equipment operates on the basis of the fast multiplication of aerobic bacteria during fermentation.
Jul 14, 2020 · Abstract. As the demand for utilizing environment-friendly and sustainable energy sources is increasing, the adoption of waste-to-energy technologies has started gaining attention. Producing biogas via anaerobic digestion (AD) is promising and well-established; however, this process in many circumstances is unable to be cost competitive with
Dec 20, 2021 · Cattle manure has high water and fiber contents, resulting in low biogas yields and degradation efficiency, which hamper an increased use of the biogas technology in agriculture ( Ahlberg-Eliasson, 2018 ). Moreover, manure might contain pathogens, potentially limiting the use of digested manure as fertilizer [summarized in Nolan et al. (2018) ].
Jul 17, 2017 · Energy losses during the digestion process include the energy lost in manure (feces and urine), in gases produced by fermentation in the gastrointestinal (digestive) tract of animals and through heat. Several processes have the potential to transform the energy in manure to usable bio-energy. Important Manure Properties in the Conversion to Energy
Sep 21, 2023 · As shown in a large number of sources, methane fermentation is the main technology that enables an economic and ecological reduction in the negative effects of manure management, while further enabling agricultural use of waste, such as digestate as a valuable fertilizer [ 49, 59, 60, 61 ].
Aug 26, 2022 · Anaerobic fermentation of manure produces a large number of degraded digestate while producing biogas. Recent technological development allows energy-efficient separation of degraded digestate into liquid (digested manure effluent) and solid fractions . As high-concentration organic wastewater, digested manure effluent has high colloidal
