Biogas production and electricity generation from a quail manure wastewater treatment system per water depth

Coturniculture, as an activity which demands low investment andquick return, is shown to be a possibility for the rural family producer.Concomitant to this, we highlight the fact that the use of liquid quailfarming waste, aimed at generating energy by anaerobic digestion,can mean a viable and promising technology for obtaining biogasfrom confined animal production systems. The growing demandfor energy establishes that new energy sources are better used,and a great opportunity for their growth may be the use of biomassin anaerobic digestion systems, in which the organic substrate isdegraded and transformed into energy and biofertilizer. The methodapplied was Biochemical Potential of Methane, through benchtopbioreactors with a volume of 250 mL, and in mesophilic conditions.Waste was used as inoculum from the manure tank of the quail eggproduction farm. The substrates used to compose the treatments wereliquid quail farming waste from the water depth treatment system,with 15, 30 and 45 days of deposition. In the results obtained, it wasverified that the best mono digestion used was inoculum+substrate of30 days of deposition, with water retention time of 45 days, showinga higher production accumulated in biogas (0.00078476 Nm3) and CH4(0.000575 Nm3) as well as the highest biogas potential of 0.0043 Nm3(kg substrate)-1. When converted into electrical energy, by means of amotor generator, using as fuel the biogas produced by the liquid quailfarming waste, the value of 104.64 kwh (45 days)-1 was obtained.
