Solid‐state anaerobic digestion (SSAD) of poultry manure is assessed utilizing a combination anaerobic leaching bed (ALBR)/plug‐flow digester. Struvite precipitation is employed concurrently with digestion to control total ammoniacal nitrogen (TAN) and prevent inhibition of methanogenic archaea. Struvite precipitation reactions are performed at a pH of 7.0 to minimize microbiological stress when leachate is returned to the digester. Results demonstrate an increase in biogas yield of 30% (470 ‐ 607 L/kgVSin) during batch digestion trials and up to 235% during semi‐continuous trials, when employing struvite precipitation methodologies. Methane content of the biogas is also shown to increase significantly (P < 0.05) when employing struvite precipitation. Of the three organic loading rates assessed (1.5, 3.0, 4.5 kg VS/m3•day) during semi‐continuous digestion, 1.5 kg VS/m3•day is shown to be the most efficient, with respect to biogas yield. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 73–82, 2017

“…If such a farm has other waste material, more experimental studies must be implemented. For example, analysing gained data of other authors (Yaldiz et al 2011), it was set, that their best result was achieved by using biomass of grass and grass silage, covered marketplace wastes, rumen waste, chicken manure, and cattle manure with a mixing rate of 57.62, 18.17, 3.81, 17.29, and 3.1%. respectively.…”

As it was already mentioned, biogas mostly consists of methane CH4 and carbon dioxide CO2, but there are other gases, which concentration is usually very low (Jingura , Matengaifa 2009;Yaldiz et al 2011;Biogaz-russia 2016) (Fig. 2).…”

Abstract. Biogas is a fuel, which can be produced from a renewable energy source -biomass. Such a gas can be freely used in small farms or food industry to produce heat or electricity. Two main components of biogas -metahne CH4 and carbon dioxide CO2. In some case, if biomass has a big amount of proteins, there can be an aggressive to different constructions gas -hydrogen sulphide H2S in biogas composition. Also, there can be other gases, such as ammonia or hydrogen, but their concentrations are very low. Nowadays it's extremely important to find a biomass with high energy potential not only to produce "green" energy, but to save the environment from gaseous emissions (greenhouse gases) and soil pollution. The aim of this study -to examine biogas yield and quality, which was produced from chicken manure biomass. To implement research, a small-sized bioreactor of periodic operation (total volume -30 l, operating volume -20 l) was used. One of the important parameters of biomass is total quality of volatile solids (VS) and quantity of organic matter in one liter of biomass (organic load -VS/l). In this research, there were examined two chicken manure biomasses with different VS and VS/l. The first one reached relatively 3188 g and 160 g/l. The second's biomass volatile solids quantity reached 1993 g and organic load was 100 g/l. Both biomasses were of the same type and organic matter (chicken manure with 39.85 % concentration of organic matter). During the experimental research, the temperature of anaerobic digestion was mesophilic (35-37 o C). The operation of bioreactor was periodic, this means, that the biomass was held in anaerobic condition till the complete degasation without any partial refill. The total experiment duration reached 66 days. It was found, that the maximum CH4 concentration reached 72.2% (biomass with organic load 100 g/l). To compare biogas yield from biomasses with different organic loading, it must be recalculated to an amount of biogas produced per day from 1 kg of volatile solids (l/d/kg VS). By implementing gained data analysis, it was discovered, that the maximum biogas yield is 7.8 l/d/kg VS (biomass with organic load 100 g/l). According to this research, it will be possible to create and use a small-sized bioreactor with chicken manure biomass in small farms to reduce pollution and generate energy.

Semi-continuous and periodic biogas production processes were investigated. Dry chicken manure containing 40.0 ± 0.5% volatile solids (VS) was used for the production of bioloading. Semi-continuous operation bioreactor and periodic bioreactor were used to implement research. Bioloading was additionally supplemented with newly prepared parts by removing 10% of decomposed mass and by adding the same amount of preheated mass every 7 days (semi-continuous process). The process was periodic when the mass was completely decomposed (after 45 days of the experiment) and fully removed (bioreactor was loaded with a new portion of raw material to 100% of the working volume again). Total duration of both experiments was 90 days. The results show that biogas production by semi-continuous process is more effective than periodic process due to higher total biogas yield (up to 39.7%) and higher methane yield (up to 33.5%). The maximum concentration of CH 4 was determined during the periodic biogas production process, but the difference was only up to 2.1% (68.9% and 66.8%, respectively). Since the produced biogas had quite high average CO 2 and H 2 S concentrations (<40.0% and 2.1 g/m 3 , respectively), it is recommended to use filter-adsorbers or biofilters. According to the results, semi-continuous type bioreactor is more effective than periodic. • Practitioner points• Maximum CH 4 concentration in biogas, produced during periodic process, is 2.1% higher than during the semi-continuous process. • Average CH 4 concentration in biogas, produced during periodic and semi-continuous process, reaches 52.7% and 53.0%, respectively. • Biogas and methane yield (during periodic process) is 39.7% and 33.5% lower than during the semi-continuous process. • CH 4 concentration decreases (after supplement) about 6.0%-7.0% (during the semicontinuous process), but increases to the next cyclic bioloading supplement. • Semi-continuous biogas production process is more efficient than periodic.
