             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.",
