Abstract
Like countries concerned about the health of their population, Côte d'Ivoire is carrying out numerous actions against waterborne diseases through the treatment of drinking water. In this study, we collected water samples from three sites on which we carried out in situ analyses as well as laboratory analyses. The results generally showed that the parameters studied comply with the chosen standard, except for nitrites and nitrates; COD and iron content. The samples were treated on a filter consisting of a layer of activated carbon from palmyra fiber topped with a quantity of sand, all in a 4.6 cm diameter column. Analysis of the filtrates showed reduction rates ranging from 19.5% to 76.6% for in situ parameters, 23.8% to 92.8% for nutrients. The reduction rates for suspended solids and COD are around 100%. These are fresh waters with a corrosive character, with a strong correlation between the parameters studied.
