Treatment Summary: | During the time of the experiment, both reactors (3,000 m3 each) worked at half capacity due to a constraint in the availability of substrate to treat. On average, the full-scale digesters were operated at a mean hydraulic retention time (HRT) of 34 days and a mean organic loading rate of 0.82 kg of volatile solids m-3 day-1. For the first four months of study, the two reactors operated at 35 °C. Reactor A was kept at this temperature during all the experiment. For digester B, the temperature was decreased abruptly to 30 °C on the 123th day and maintained at this level for 2 HRTs until the 190th day. Then, the temperature was modified to 25 °C and maintained for 3 HRTs (between the 191st and the 373th days). Finally, the heating of reactor B was increased from day 374 onwards to reach the initial temperature of 35 °C. |
