A bacterial inoculum previously acclimated to the substrate was used. Organic material removal efficiencies of 62.2%, 85% y 94% were obtained with retention times of 5.14, 6.01 and 8.01 hours, and with volumetric organic loads (Lv) of 7.68, 6.19 and 4.61 kg/day.m3, respectively. Also, the kinetic mass transfer constant (k) was calculated and it presented a value of 0.02 m/day. On the other hand, an F/M ratio of 0.4 was determined, indicating that the process had a similar performance to an extended aeration system. Finally, the biomass generated inside the reactor was analyzed, obtaining a value of 11560 mg /L, which is a higher value than those of conventional systems.</p>}, number={4}, journal={Enfoque UTE}, author={Muñoz, Marcelo and Reina, Jessica and Aldás, María Belén}, year={2016}, month={Dec.}, pages={pp. 31 - 42} }
