| الوصف: | Valorisation of the supernatant of brewery effluent in plankton production for fish farming: an alternative for environment protection in southern countries Description of the subject. Identifying optimal conditions for the use of brewery effluents in phytoplankton production. Objectives. To determine the nutrient potential of the supernatant of this effluent, conditions for its use in phytoplankton production and the depollution that results from its use. Methods. Firstly, the supernatant of the effluent was analyzed. Five triplicate treatments were then seeded with Scenedesmus quadricauda, and followed for 27 days through measurements of biomass and physicochemical parameters. Finally, abatement rates of the initial polluting loads were determined. Results. Although the supernatant does not comply with the Benin standard, it does have a high nutrient potential. Not neutralizing the acidic initial pH led to a delay in algal growth. The treatment that contained 10% supernatant presented the highest algal production and significant reductions in polluting loads. Conclusions. In contexts where there is no functional wastewater treatment plan, it would be interesting to set up a win-win partnership between breweries and fish farmers. Optimal conditions would include optimal dose and prior pH neutralization. |
