Mesophilic anaerobic digestion of damask rose bagasse with different proportions of cattle manure

摘要: Doaguie, A.R., A. Ghazanfari, L.G. Tabil. 2012. Mesophilic anaerobic digestion of damask rose bagasse with different proportions cattle manure. Canadian Biosystems Engineering/Le genie des biosystemes au Canada 54:8.1-8.6. The flowers plants (Rosa damascena Mill.) are utilized in hydro-distillation industries to produce concentrated water and essential oils. Rose is the main byproduct these that conventionally used as compost. objective this research was investigate potential kinetics biogas production from mixed manure mass 95, 90, 85 80%. process carried out at two temperatures 35 45°C for 30 days hydraulic retention time. daily pH, generated methane were measured. results indicated rate increased increase proportion cow temperature. Maximum cumulative yield 0.427 0.369 m/kg volatile solids 45oC 35oC, respectively. reductions various treatments ranged 64.9 81.4%. modeled using a modified form Gompertz equation resulting R values greater than 0.94.
