Abstract
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.
Highlights
IntroductionThese industries are localized in various areas of the different industrial zones [1]
All the measured values are lower than 40 ̊C, respecting Classified Installations Inspection Service (CIIS) recommended temperature in the case of discharge of effluents towards environment [9]
The high alkaline pH values recorded in 29.00% of the soap factories studied can be explained by the different activities related to the use of alkaline agents in soap formulation
Summary
These industries are localized in various areas of the different industrial zones [1]. The increase of soap industries is due to the increase of human beings needs in term of soap, detergent and cosmetic This soap factories growth participates to this ecological disaster. These soap factories, like the other industries, are mainly concentrated in the area of Abidjan. That is why more complete physicochemical characterization constituted the first step to be taken into account in order to estimate the level of pollution of this type of industrial waste
