Activated coal obtained from mango residues is an alternative for the valorisation of these wastes for applications. This work focuses on the production of a new adsorbent from mango residues collected in the urban common of Mamou (Republic of Guinea) by chemical activation with potassium hydroxide. To do this, the different rates: humidity, cinders, volatile matter, fixed carbon et iodine indices before activation and after activation at 400°C and 700°C were determined which are: (6.28%;0.97%;73.80%;25.23%) respectively. The best indices were found in powdered activated coal compared to grain activated coal for the concentrations used. This study can be an alternative bio-adsorbent for the urban community of Mamou in water treatment.

The valorization of agricultural waste in the treatment of our rivers can be an alternative to waste management. This study deals with the use of mango kernel shells in the depollution of the Bafing River (rural commune of Tolo, Mamou prefecture) in the Republic of Guinea. Thus, the different concentrations of ions found in April (low water period) were determined and which are: a reduction of 35.64 mg/l (79.69%);a reduction of 41.53 mg/l (81.24%);and 47.53 mg/l (82.10%) and 3.83 mg/l (75.24%);8.45 mg/l (81.72%);11.67 mg/l (87.94%) at the sampling points P1, P2, and P3 respectively. In October (flood period), the concentrations found are 24.98 mg/l reductions (79.88%);29.83 mg/l reduction (81.41%) and 35.15 mg/l (85.50%) at the same sampling points P1, P2 and P3, respectively. This study can be considered as a water treatment alternative for the village community of the Tolo sub-prefecture (Mamou prefecture).

The aim of this work is the purification of wastewater by double filtration on granular activated carbon prepared from peanut shells. The samples of carbonized peanut shells were activated with 35% sulfuric acid and finally, we proceeded to the purification tests on double filtration of wastewater. Granular activated carbons (GAC) were very effective for the treatment of turbidity, dissolved oxygen, suspended solids, iron, COD and BOD5 but the best results were observed with nitrite, nitrate and phosphate. However, the second filtration was the most efficient while the lowest rates were observed for pH (17.91% on average), and conductivity (29.71% on average). In addition, this work has allowed increasing the dissolved oxygen by more than 50.16% at the exit of the first filter and more than 105.36% at the exit of the second filter. This study shows that granular activated carbon prepared from peanut shells could be a credible alternative for developing countries in the control of pollution and environmental protection.
