Résumé : Five 1-L Erlenmeyer mini reactors were installed in the FL 12 laboratory at the Gaston Berger University in Saint Louis to test anaerobic co-digestion between cow dung and Typha domingensis. To boost bacterial activity, a ceramic type biological activator was used to see what impact this might have on biogas production. In order to respect the experimental procedure, the mini-reactor (A) was considered as a control, i.e., without biological activator. In the B, C, D and E mini-reactors, 2g, 4g, 6g and 8g of biological activator were added respectively. A magnetic stirrer was also used to limit temperature variation and ensure the homogeneity of the reaction medium. Differential behaviour was observed during the codigestion process due to the changing density of the solution and the action of the biological activator on each mini-reactor. The mini-reactor that produced the most biogas was D, which received 6g of activator, with a maximum production of 3436 ml, and this production decreased from the second day of the test.
