Co-Digestion of Orange Pulp and Cattle Manure with Different C/N Ratios and A New Modeling of Biogas Production

Utilization of Co-digestion of Local Brewery Wastes and Cattle Dung as a Potential Source of Biogas and Organic Fertilizer

Biogas production from co-digestion of local brewery waste (BW) and cow dung (CD) was study for value added to this solid waste. The objective of this research was to fine the optimum condition for maximum biogas production and also examined the effectiveness of the biogas residue (liquor from anaerobic digestion process) as a nitrogen source for the production of okro. The experiments were per...

Effect of Physical and Chemical Operating Parameters on Anaerobic Digestion of Manure and Biogas Production: A Review

Introduction: The need for food produced from animal husbandry has made it a growing industry which result in increment of livestock waste. On the basis of environmental and economic considerations, these materials require treatment and management. Anaerobic digestion and creation of biogas are the most effective methods of waste management. Several parameters affect the anaerobic digestion of ...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

A new kinetic model for biogas production from co-digestion by batch mode

Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. Thus, the goal of this study is to develop a new kinetic model of biogas production with meani...
