abstract = "New data on biogas production and treatment of cattle wastewater
were registered using an upflow anaerobic sludge blanket-anaerobic
filter (UASB-AF) hybrid reactor under mesophilic temperature
conditions (37 °C). The reactor was operated in semi-continuous
mode with hydraulic retention times of 6, 5, 3 and 2 days and
organic loading rates of 3.8, 4.6, 7.0 and 10.8 kg CODt
m\−3 d\−1. Biogas volumes of 0.60.8 m3 m\−3
d\−1 (3.84.6 kg CODt m\−3 d\−1) and 1.21.4 m3
m\−3 d\−1 (7.010.8 kg CODt m\−3 d\−1),
with methane concentrations between 69 and 75%, were attained. The
removal of organic matter with values of 6081% (CODt) and 5175%
(CODs) allowed methane yields of 0.1550.183 m3 CH4 kg\−1
CODt and 0.4010.513 m3 CH4 kg\−1 CODs to be obtained.
Volatile solids were removed in 34 to 69%, with corresponding
methane yields of 0.27 to 0.42 m3 CH4 kg\−1 VSremoved. The
good performance of the novel hybrid reactor was demonstrated by
biogas outputs higher than reported previously in the literature,
along with the quality of the gas obtained in the various
experimental phases. The hybrid reactor investigated in this study
presents comparative advantages, particularly in relation to
conventional complete mixture units, considering economic factors
such as energy consumption, reactor volume and installation
area.",
