Potential recovery of bioenergy from swine wastewater treated in UASB reactors
Keywords:
bioenergia, biogás, metano, simulação, suinoculturaAbstract
A modeling was carried out to estimate the fraction of methane and bioenergy recovered in different pig farms, treating wastewater in ascending anaerobic sludge blanket reactors (UASB) considering the probable losses throughout the process. Methane production and electrical power ratios of respectively 118,39 NL KgDQOrem-1 and 11,13 KWh Nm-3biogás were obtained. The regressions were analyzed and their ability to be accurate in estimating available bioenergy was verified.
