MARTINEZ NODAL, Pastora de la C. et al. Reduction of the environmental impact of oleaginuos water by means of a fix bed column filled with sugar cane bagasse. cen. az. [online]. 2016, vol.43, n.1, pp. 61-69. ISSN 2223-4861.

From the environmental assessment conducted in the centrifugation process fuel that is used as raw material for generating electricity in Power Plants (CE) operating with diesel and the physicochemical characterization of oleaginuos water (ARO) that it generates, it was performed the environmental impact assessment of these waters if they are discharged without any treatment. A matrix of importance was made, which allowed us to identify the impact on the actions and factors by the activity and the generated waste. From the physico-chemical characterization of ARO, a sustainable treatment is proposed with the use of a fixed-bed column filled with sugar cane bagasse as biosorbent material to minimize the environmental impact caused by oleaginous water if spilled. A physicochemical characterization was made to the natural sugar cane bagasse in terms of moisture, density, porosity and high adsorption capacity. The results allowed to define the fraction of interest (+1 -2 mm), given by the performance in the screening (41%), the homogeneity of this fraction and sorption capacity (2g diesel/g BN). The breakthrough curve was obtained by a continuous flow system 2 l/h of ARO through a fixed bed of 59.997 g of BN and an initial concentration of hydrocarbon of 1444.9 mg/l. Studies showed that the sugarcane bagasse has potential as biosorbent oil, achieving a significant removal of the indicator total hydrocarbon, of 65%.
