The feasibility of applying the UASB concept for the anaerobic treatment of stillage of distilleries in the sugar producing area of Argentina was subject to study. Results obtained in a 100-l UASB reactor treating stillages with COD values between 35 and 100 g COD/l are presented. Loading rates of up to 24 g COD/l/day, were applied with an average COD removal of 75% and a biogas production of more than 9 l/l/day, with an average methane content of 58%. The settling velocity distribution of sludge particles would indicate a good formation of biomass pellets. System interruptions of months without feed and at ambient temperature (20-24/sup 0/C) were well tolerated.
