2022/3/22/ · Lignocellulose degradation (LCD) was the key factor limiting the development of anaerobic fermentation (AF) by the cow dung (CD). In the research, the effects of cellulase pretreatment (CP) and microvoltage (MV) alone and combination on the gas production and LCD during the AF were investigated. The results showed that both

2020/9/1/ · 1. Introduction. Biogas technology is widely employed to treat the waste generated from the livestock and poultry farming. The production, biogas, is potential energy in current society [1], [2].Meanwhile, soluble organic matter can be removed from the wastewater, achieving the removal rate as high as 85–90% [3].However, besides the

2017/7/2/ · Conclusions. It has been shown in this study that locally fabricated anaerobic digester can be used to produce biogas, using animal dung like cow and fowl dung. The experimental data obtained signified that high caloric feedstock with high carbohydrate and low fats contents could yield more biogas than other materials.

2018/10/15/ · Anaerobic fermentation is considered as a cost-effective way of biomass waste disposal. Chromium (Cr) is one of the heavy metals that often been blamed for unsatisfactory operation or failure of anaerobic fermentation. Process analysis of anaerobic fermentation of Phragmites australis straw and cow dung exposing to

2023/8/1/ · Anaerobic digestion. The cow manure was collected from a local dairy farm in Lanzhou, China. The total solid (TS) and volatile solid (VS) of cow manure was measured. Cow manure samples were used as AD substrates. The batch reactors were 250 mL glass bottles with a working volume of 200 mL.

Latvia University of Life Sciences and Technologies, Latvia imants.plume@llu.lv, vilisd@inbox.lv. Abstract. Anaerobic fermentation (AF) is widely implemented technology for energy and organic fertilizer production in more than 50 biogas plants in Latvia. Increasing the efficiency of the anaerobic fermentation process plays an important role

2012/2/1/ · Project of Yunnan Province (2009CD044). Summary. ⑴ Anaerobic fermentation of cow dung and slurry from hydrogen fermentation production of sucrose. by using anaerobic batch fermentation at

2016/2/9/ · The effect of ferrous (added as FeCl2) on the anaerobic co-digestion of Phragmites straw and cow dung was studied by investigating the biogas properties, pH values, organic matter degradation (COD) and enzyme activities (cellulase, protease and dehydrogenase) at different stages of mesophilic fermentation. The results showed that

2014/5/1/ · In the anaerobic fermentation process, the carbon/nitrogen (C/N) [43], for co-fermentation of cow dung compost, with glucose and apple pomace at C/N ratio of 10.6. A lower HY of 4.8 mol-H 2 ...

2022/8/1/ · Cai et al. (2022) studied the enhancement of anaerobic fermentation of cattle manure, and the results showed that cellulose pretreatment and micro-voltage have significant influence on anaerobic

2018/12/1/ · Impacts of adding different amounts of cow manure (CM) on the anaerobic digestion (AD) of oat straw (OS) with total solids content (TS) values of 4%, 6%, 8% and 10% was assessed over 50 days using batch experiments. The addition of CM at the content below 2/3 increased the methane yield and reduced the start time of

The results showed that a specific methane yield of 0.333 and 0.345 LCH4/gVSr was obtained at 35oC in the fermentation systems for a dilute ratio of 1:1 and 1:0, with a VS removal of 50.01%, and

2016/9/19/ · The effects of cabbage waste (CW) addition on methane production in cow dung and corn straw co-fermentation systems were investigated. Four experimental groups, each containing 55 g of substrate, were set up as follows: 100% cow dung (C); 36% cabbage and 64% cow dung (CC); 36% straw and 64% cow dung (SC); and 18%

2023/10/1/ · The current study explored bioenergy, particularly biohythane (a combination of biohydrogen (bioH2) and biomethane (bioCH4)), production from cow dung and untreated domestic wastewater sludge to valorize the waste into a value-added product. The experimental study consisted of a two-step process: dark fermentation (DF) and …
