2021/1/1/ · The effect of substrate (food waste and cow dung) and inoculum (sludge solution) ratio on the hydrogen fermentation is experimentally investigated in this study. Five reactors are prepared using various ratios of substrate and inoculum on volume basis and the hydrogen (H 2 ) and carbon dioxide (CO 2 ) generation is observed for 15 days.

2016/12/1/ · bic fermentation of organic matter from methanogenic . ture also suggest that biological waste like cow dung can . ... tract on an intensive care unit. J Antimicrob Chemother 58:853–856 ...

2016/6/1/ · Along with the production of novel chemicals, many cow dung microorganisms have shown natural ability to increase soil fertility through phosphate

2020/4/16/ · At medium temperature, the biogas output per unit of pig manure/corn straw is better than that of cow manure/corn straw. When the ratio of pig manure to corn straw is 9:1, the maximum gas production is 283.74 mL/g TS; when the ratio of cow manure to corn straw is 7:3, the minimum gas production is 121.59 mL/g TS.

2020/9/20/ · The result suggested that proper substrate to inoculum ratio is the deciding factor to improve the fermentation process. A ratio of food waste and cow dung with sludge solution (1:3) appeared the

Four sets of 250 ml conical flasks (A-D), each containing two flasks, were used in triplicates as digesters to determine the possibility of laboratory-scale biogas production from cow dung under four different treatments. Equal volumes of slurry (3 g dung: 10 cm3 water) in the digesters were subjected to anaerobic digestion over a four-week retention period,

2018/3/1/ · About 40–50% of the VS in cow-dung manure are decomposable ligno-cellulosic materials that can be transformed into CH 4 or biogas (Jha et al., 2012, Owamaha and Izinyon, 2015). Angeriz-Campoy et al., 2015 , Dhar et al., 2016 investigated that FW is an applicable co-substrate for the improvement of hydrogen generation in dark

2012/12/1/ · When the temperature was the same, total solid (TS) which was 8% was the good choice for anaerobic fermentation, while the TS was same,37°C was the choose to get the maximum yield of the methane

2023/3/13/ · Cow dung is a possible sustainable material of the future, study finds. by University of Bristol. Graphical abstract. Credit: International Journal of Biological Macromolecules (2023). DOI: 10.

Considering its closed design and high automation, our In tank composting system has high efficiency in speeding up composting. Commonly, it takes about 20-25 days when your animal manure becomes good organic fertilizer powder, if you use compost turning machines to turn your compost. However, our fermentation tank makes it possible to

2010/10/1/ · Anaerobic treatment of undiluted cow dung (15% total solids), so-called dry fermentation, produced hydrogen (743 ml-H(2)/kg-cow dung) at an optimum temperature of 60 degrees C, with butyrate and

2020/7/28/ · Biohydrogen production from organic solid waste has shown particular advantages over other owing to the combination of waste reduction and bioenergy production. In this study, biohydrogen production from the co-digestion of cattle manure and food waste was optimized in a mesophilic semi-continuous process. To maximize
