EVALUATION DE LA QUALITE PHYSICO-CHIMIQUE DES RESIDUS DU COMPLEXE AGRO-INDUSTRIEL DE BANDA/SARH (TCHAD)
Journal Title: Larhyss Journal - Year 2016, Vol 25, Issue 25
Abstract
This work, which has been carried out in the Sugar Company of Chad, has focused on the physic-chemical characterization of the residues of the agroindustrial complex of Banda/Sarh in southern Chad and on the quality of the water of the pumping stations of this company. The pH, conductivity, temperature, phosphate and silica were determined on five samples of water for cane washing. The chemical compositions of the molasses, bagasse and defecation scum were also determined. The results of physic-chemical analyzes of the water have given values ranging from 7,1 to 7,4 ; from 86,88 to 87,58 µs/cm; from 0,10 to 0,14 mg/L and from 22,7 to 24,2 mg/L respectively for the pH, the conductivity, phosphates and silica. The average moisture of scum, of molasses and bagasse are respectively 77, 15 %, 47, 44 % and 7, 8 %. The rates of pollution are respectively 2, 81% for the scum, 3,18% for the bagasse and 32,77% for the molasses. The bagasse contains 4,0 % of nitrogen and 37,0 % of cellulose. The values of the physic-chemical parameters obtained in the water samples of the agro-industrial complex, which are all consistent with the WHO standards, are acceptable for the washing of canes and for the supply of the energy production equipment. In the light of the results obtained on the residues of the agro-industrial complex of Banda, the scum, the bagasse and molasses can also be valued in the fertilization of the soil as well as in cattle feeding.
