The Kinetics of Methane Production from Co-digestion of Cattle Manure
Zh.K. Bakhov, K.U. Korazbekova and K.M. Lakhanova

Abstract:
In this article, the kinetics of methane production from co-digestion of liquid manure from cattle with the addition of winemaking waste, food waste and biowaste was investigated in order to describe and evaluate methanogenesis in terms of growth curve of methanogenic bacteria. Experiments were carried out in «Hohenheim» biogas yield testing system at the temperature of 37°C. The cumulative methane yield was 0.330±0.038, 0.277±0.041, 0.148±0.013 and 0.250±0.025 m3 CH4 per kg oDM in normal condition, respectively in mono-digestion and co-digestion of liquid manure from cattle with winemaking, food and biowaste. The kinetic Gompertz parameters of methane production (P-potential yield of methane, Rm-maximum methane production rate and λ-duration of lag phase) were analyzed. The highest potential methane yield (P) showed co-fermentation of liquid manure from cattle with biowaste 0.387 Nm3 (kg oDM)-1, the highest methane production rate (Rm) was 0.022±0.003 Nm3 (kg oDM) -1 day-1 for mono-digestion of cattle slurry, the lowest 0.006 Nm3 (kg oDM)-1 day-1 was obtained during co-digestion with food waste. Duration of lag phase (λ) was within 10.17-14.60 days for all samples. Additional, the duration of digestion to produce 95% of the potential methane yield and efficient methane production was determined.
