The kinetic study shows that the kinetic constants are classified in the following order: 0.11; 0.15 and 0.17 min-1, respectively for 0.006; 0.2 and 0.340 g / l. In the other hand, for the faecal enterococci, complete inhibition was observed after 5 minutes of exposure at all concentrations used (0.006; 0.2 and 0.340 g / l).

This application is not limited to a simple transposition of the Walloon model. The Burkina context calls for adaptation to the local environmental and socio-economical realities with an adequate partnership management. The importance of the mobilization around this project of institutional partners, as well as local collectivities, agricultural producers and water users in general reveals the great expectations of the actors concerning this new tool of water participative management. But will the latter be equal to the task? A first assessment has been drawn up one year after the launch. During the first year of the project, a participative diagnostic was implemented but the understanding of basic notions of water management such as ‘river’ (not translatable in the local language), ‘watershed’, ‘con...

The 50 sites studied are the object of a physicochemical and environmental characterization followed by a floristic survey (phanerogams, mosses, liverworts, and macroalgae). Six clusters of watercourses with their characteristic species are highlighted by two-way clustering and indicator species. The abundance of phanerogams in some watercourses of the Arden region is not only linked to light intensity but also depends on the degree of slope and the nature of the geological substrate.

De ce fait, l’intégration de procédés biologiques de traitement des eaux de consommation pourrait être une alternative durable dans l’amélioration de la qualité des eaux de boisson, du fait de la disponibilité et de la non-toxicité des substances. La présente étude porte sur l’optimisation de l’efficacité des graines de Moringa oleifera dans l’assainissement des eaux de consommation en milieu rural au Burkina Faso. Des eaux de surface et de puits alimentant les populations ont été traitées avec différentes concentrations de coagulant de graines de M. oleifera. Le suivi de paramètres physico-chimiques et microbiologiques à différents temps de décantation a permis de déte...
