“…Lack of certain nutrients deteriorates the performance of AD and may change the degradation pathways leading to a build up of intermediary products such as propionate. Results by Vintiloiu et al (2012) showed strong statistically signicant eects of macro-and micro-nutrients on the stability of the anaerobic process of agricultural biogas plants in Germany. Nickel, molybdenum, and sulfur showed the strongest eects, followed by selenium, whereas iron, cobalt and sodium only showed effects in combination with other elements.…”

“…Together with the fresh maize silage, a certain amount of micronutrients were also added to the reactors, providing necessary nutrients for microbial growth and avoiding biological process disturbances. The dosage and the composition of the micronutrients was based on Vintiloiu et al's [11] recommendation. The maize silage in the leach-bed reactors was slowly decomposed and turned into a leachate rich in organic acids and alcohols.…”

Abstract:The effect of organic loading rate (OLR) on a pressurized anaerobic filter was studied in a laboratory two-phase anaerobic digestion system. The anaerobic filter was operated successively at two working pressures (9 bar and 1.5 bar). The OLR (COD) for each pressure was increased from 5 to 17.5 kg·m. The best performance of the reactor at 9 bar was observed at OLR (COD) of 12.5 kg·m and COD degradation grade of 90.6%. At higher OLRs and shorter HRTs, the process became unstable. In contrast, there was no indication of digester failure during the experiments at 1.5 bar. The SBP peaked at OLR (COD) of 17.5 kg·m , the reactor at 9 bar had the same specific methane yield as at 1.5 bar, which was in the range of 0.31-0.32 L N ·g −1 COD.Raising the working pressure in the reactor resulted in an increase of methane content of the produced biogas. However, the low pH value (approximately 6.5) inside the reactor, induced by high CO 2 partial pressure seemed to limit the reactor performance at high OLRs and short HRT.

“…Adding trace elements to the biogas process has been shown to increase the methane production of the process , Vintiloiu et al 2012. The requirements for a better nutrient balance can be achieved by the co-digestion of energy crops with manure, which contains more trace elements (Cavinato et al 2010), and with a large variation of feedstock, including different variations of organic wastes, which seems to improve the abundance of trace elements (Schattauer et al 2011).…”

Esitetään Jyväskylän yliopiston matemaattis-luonnontieteellisen tiedekunnan suostumuksella julkisesti tarkastettavaksi yliopiston Ylistönrinteellä salissa YAA303 syyskuun 27. päivänä 2013 kello 12.Academic dissertation to be publicly discussed, In this thesis, the methane production potential of traditional and novel energy crops was evaluated in boreal conditions. The highest methane yield per hectare was achieved with maize (4 000-9 200 m 3 CH4 ha -1 a -1 ) and the second highest with brown knapweed (2 700-6 100 m 3 CH4 ha -1 a -1 ). Recently, the most feasible energy crop, grass, produced 1 200-3 600 m 3 CH4 ha -1 a -1 . The specific methane yields of traditional and novel energy crops varied from 170-500 l kg -1 volatile solid (VS). The highest specific methane yields were obtained with maize, while the novel energy crops were at a lower range. The specific methane yields decreased in the later harvest time with maize and brown knapweed, and the specific methane yield of the grasses decreased from the 1 st to 2 nd harvests. Maize and brown knapweed produced the highest total solid (TS) yields per hectare 13-23 tTS ha -1 , which were high when compared with the TS yields of grasses (6-13 tTS ha -1 ). The feasibility of maize and brown knapweed in co-digestion with liquid cow manure, in continuously stirred tank reactors (CSTR), was evaluated. According to the CSTR runs, maize and brown knapweed are suitable feeds and have stable processes, producing the highest methane yields (organic loading rate 2 kgVS m -3 d -1 ), with maize at 259 l kgVS -1 and brown knapweed at 254 l kgVS -1 . The energy balance (input/output) of the cultivation of the grasses, maize and brown knapweed was calculated in boreal conditions, and it was better when the digestate was used as a fertilizer (1.8-4.8 %) than using chemical fertilizers (3.7-16.2 %), whose production is the most energy demanding process in cultivation. In conclusion, the methane production of maize, grasses and novel energy crops can produce high methane yields and are suitable feeds for anaerobic digestion. The cultivation managements of maize and novel energy crops for biogas production require further research.
