Assessment 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 ...
متن کاملMicrobial 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 کاملComparative Study of Composting and Anaerobic Digestion as a means of Animal manure stabilization: A Case of Cow dung
. Abstract: The practice of using cow dung for soil conditioning and fertilization dates back to the early history of man, even though, it has received greater attention in recent times due to high cost of chemical fertilizer as well as the environmental impacts on sustainable agriculture. This study explores the three methods of cow dung stabilization namely: composting in 3m depth compost pit...
متن کاملanaerobic digestion of nssc pulping effluent
two uasb reactors r-i and r-ii, each of 10liters capacity, made up of acryl material wereoperated parallel and continuously for a period of 220 days, using actual effluent of the nssc pulp and papermill, at mesophilic temperature and neutral ph. the main objective was to investigate the treatabilityperformance of the reactors at varying olr and hrt in terms of toc and lignin removal. the reacto...
