abstract = "This study evaluates the treatment efficacy and biogas yield of an
integrated system composed of a plug-flow biodigester (with sludge
recirculation) followed by polishing in a stabilization pond. The
system was operated in real scale for 12 months at ambient
temperature and under continuous flow. The volumetric yields of
biogas varied according to the organic loads applied, between 114
and 294 Kg COD day\−1, reaching levels of 0.026 to 0.173 m3
m\−3 day\−1, with concentrations of CH4 between 56
and 70%. The monthly biogas productions were between 378.5 and
2186.1 m3 month\−1 equal to an energy potential of
approximately 2070 to 19,168 KWh month\−1.The average
yearly removals of BOD5,20 and COD by the integrated treatment
system were 70 and 86%, respectively. The average annual removals
of NH4 and TKN were 88.5 and 85.5%, respectively. The pH values
were always near neutral, and the alkalinity was in ranges
propitious for anaerobic digestion. The results of this study
indicate good efficacy in terms of removal of organic matter and
nitrogen compounds, with the added benefits of generation of
energy and use of the treated effluent as biofertilizer, enabling
significant cost reductions to cattle farmers.",
