2019/10/29/ · Except for U5, the biogas production rate of each experimental group changed significantly during the 50-day fermentation process, and the biogas production peak was obvious. The biogas production period was concentrated mainly during the 8th to 25th days. The peak of U5 biogas production was concentrated mainly during the 17th to
2023/12/1/ · Besides the added biogas slurry variation, the fermentation system also changed gradually after a long-term operation of biogas slurry addition. Fermentation broth samples were taken from the reactors in a steady period (the 50th day before the routine feeding). DNA and RNA samples of fermentation broth and fresh biogas slurry were
2022/8/17/ · Purpose As a high-yield by-products of biogas engineering, biogas residue (BR) are limited in the application of soil fertility due to their ecological threat. Therefore, conversing BR into biochar is to be considered. However, whether BR biochar still had ecological risk to soils (especially the widely distributed soils such as Ultisol soil)
This study used biogas residue produced by anaerobic fermentation of food waste as the raw material in large-scale windrow composting. The effects of the addition of a microbial consortium on the physical and chemical properties and stability of composting of biogas residue were studied. The maturit

2022/3/1/ · The average long-term biogas yield of the biogas station under investigation is 130.5 m 3 t −1 which (related to dry weight of feedstock and after conversion to CH4 at 0 °C and 101.3 Pa) is 5% lower than reported by Samarappuli and Berti (2018) and some 6% lower than reviewed by Böjti et al. (2017). The reason may be that the
2023/10/19/ · In this study, the environmental and economic aspects of six integrated biogas and digestate operation modes, i.e., biogas utilization (direct combustion,
2021/4/20/ · Modified biochars prepared from straw, pig manure, and chicken manure biogas residues were used to adsorb and remove ammonium nitrogen (NH4+-N) and chemical oxygen demand (COD) in wastewater. The results showed that at 400–600°C, the adsorption performance of the biogas residue biochars increased with pyrolysis
2022/11/1/ · For the ASBR system as shown in Fig. 5 (b), the pretreatments of food waste were basically identical to the conventional CSTR system, while the co-hydrothermal pretreatment was applied to sewage sludge and biogas residue in the ASBR system. The sewage sludge and biogas residue were heated to 180 °C by 200 °C steam.
2012/9/1/ · 1. Introduction. Energy crisis and global warming are considered to be two most serious problems worldwide [1].Biomass energy, as a renewable and sustainable form of energy, is becoming more important due to its environmentally-sound and energy-saving production [2].Development of a livestock industry is believed to be a key
Biogas generators efficiently use organic waste to produce gas and power, turning everyday rubbish into valuable energy products. A biogas generator is a key solution in sustainable energy production. Let's explore how they work: Starting with Organic Waste: The process begins with the collection of organic waste.
