Abstract: | The present research work attempts to investigate the solubility and the biodegradability of the liquid wastes of olive presses in three Algerian regions (Mila, Jijel, and Bejaia) in anaerobic mode. The experiments were carried out in a series of reactors of 150 ml and 250 ml at a mesophilic phase (37 ° C) and a thermophilic phase (55 C). Before the incubation of the liquid wastes of olive presses and the sewage waters, the characteristics of the three regions allow for good solubilization. After the incubation was conducted, the solubility of the liquid wastes of olives presses at Jijel proved to be the best with a DCOS / DCOt ratio of 88.88%. Similarly, the study of biodegradability, by the process of anaerobic digestion in a mesophilic and a thermophilic phase, revealed that the incubation of the liquid wastes of olive presses and the sewage waters at Jijel provides the best production of both biogas and methane in particular with an order of 283 ml / gTVS for methane in a mesophilic phase and of 192.25ml / gTVS in a thermophilic phase. |
