摘要：

The present work was a comparative study of four types of biodigesters systems upflow anaerobic sludge blanket (UASB) operating with brewery effluent in hot climate region. In case a UASB IC 20 meters high and 660 m(3) in volume in steel protected by epoxy resin, a conventional UASB 6 feet tall with a volume of 965 m(3) protected concrete with high density polyethylene (HDPE) film, a conventional UASB 6 feet tall with cylindrical volume of 2,000 m(3) protected steel, and end a digester system consists of two UASB arranged in series, plug flow, forming cascade of 0.5 m(3) volume at 1.2 m height each, built in HDPE rotomolded. Both systems operated hydrolyzed receiving tributary. The hydraulic retention time varied between 2.66 and 24 hours, removing the organic load of between 70% and 91% and the methane concentration between 75% and 81%. Preliminary results allowed the comparison of performance and eco-efficiency of both systems studied when objective environmental sanitation and/or bioenergization of wastewater from the brewery.
