Cobalt nanoparticles to enhance anaerobic digestion of cow dung: focusing on kinetic models for biogas yield and effluent utilization
نویسندگان
چکیده
The impacts of Co nanoparticles (NPs) on the anaerobic digestion (AD) cow dung were investigated using kinetic models (modified Gompertze, logistic, and first-order) experimental measurements. deviation between predicted measured data for biogas yield with modified Gompertze logistic 0.66–2.26% 1.43–4.19%, respectively. addition NPs (1–3 mg/L) improved hydrolysis rate (K) value by 66.66–144% compared control. Furthermore, fertilizer efficiency effluent was comparable to that commercial NPK compound fertilizer. combination measurements can effectively quantify impact AD performance provide an informed choice industrial production.

Microbial Dynamics during Anaerobic Digestion of Cow Dung
The anaerobic digestion of cow dung was investigated for 30days in a laboratory scale batch reactor. Totally nine bacterial strains were isolated from cow dung slurry. The bacterial isolates were preliminarily examined by morphological characteristics and they were further confirmed by 16S rRNA sequencing and analyzed through BLAST. Microbial dynamics showed that hydrolytic bacterial population...
متن کاملAssessment of the effects of dry anaerobic co- digestion of cow dung with waste water sludge on biogas yield and biodegradability
Dry anaerobic digestion has been treated as feasible process for potential renewable energy recovery with nutrient-rich fertilizer and sustainable solid waste management. Dry methane fermentation of undiluted cow manure (CM), waste water sludge (WWS) and their mixtures into different ratios were conducted at 35°C in the laboratory-scale single-stage batch reactors for 63 days. The specific biog...
متن کاملAssessment of biofertilizer quality and health implications of anaerobic digestion effluent of cow dung and chicken droppings
Anaerobic digestate have been identified as a rich source of essential plant nutrients. Nevertheless, its safety measured by the concentration of pathogen present is of great concern to end users. This research explored the efficiency of the mesophilic biodigestion process in the stabilization and sanitization of cow dung and chicken droppings. Six (6) kg each of cow dung and chicken droppings ...
