The problem of water depollution is gaining importance, especially as regulatory standards concerning drinking water are increasingly strict. The different industries (textile industries) generate chemically stable pollutants such as methyl orange which make their degradation difficult. It is therefore necessary to find new, more effective techniques for the treatment of these discharges. Among the different solutions proposed to deal with this problem, we find advanced oxidation processes (POAs) which are clean and promising technologies in the field of wastewater depollution. In this regard, heterogeneous photocatalysis was used in an aqueous suspension of titanium oxide (TiO2) using a ultraviolet (UV) lamp as artificial radiation. The objective of this work is to study the influence of some operating parameters such as: the catalyst mass, the initial pollutant concentration, the volume of the solution and the pH of the solution, were examined. The results obtained showed that this photocatalyst made it possible to degrade 99.85% of the initial concentration of methyl orange (10 ppm), after 240 min of irradiation with an optimal mass of 0.50 g of TiO2 for a volume of 200 mL of methyl orange solution at pH = 3.0.

Physico-Chemical Characterization of Industrial Liquid Discharges of Soap Factories in Abidjan, Côte D’Ivoire

This work deals with the efficient management of industrial liquid discharges from soap factories (ILDS) in the region of Abidjan. The aim of this work is to evaluate the physico-chemical quality of these discharges as well as the different types of pollution generated. Seventeen (17) industrial soap sources were studied through fourteen (14) global pollution parameters (T, pH, electrical conductivity EC, redox potential EH, suspended matter SM, COD, BOD5, biodegradability factor BF, , , , , total iron and ). A liquid waste collection campaign was done during six weeks from February to March 2016, corresponding to a period of intensive activity of these industries. The samples were analyzed according to the norms of the French Standardization Agency (AFNOR). Results were compared with the Ivorian guide values recommended by the Classified Installations Inspection Service (CIIS). Principal Component Analysis (PCA) is allowed to evaluate the pollution induced by these factories’ rejection. In addition, Ascending Hierarchical Classification (AHC) method leads to classify soap factories into three groups according to the physico-chemical quality of their releases. Moreover, the estimation of the biodegradability factor is permitted to know the state of the biodegradability of these effluents.
