This work deals with Wastewater treatment plant deterioration in connection with effluents from a cosmetics production unit in Abidjan, Côte d’Ivoire. It highlights the chemical impact of these effluents on wastewater treatment infrastructures by underlining the importance of systematic assessment for predicting harmful effects on the environment and public health. The study uses predictive models to analyze the chemical composition of effluents to identify potentially toxic substances and propose recommendations for sustainable waste management. Colorimetry, gravimetry, AFNOR, and Rodier analysis methods were used during four sampling campaigns. The results of this study show that the effluent has average pH, temperature, and redox potential values equal to (5.22), (24.23 °C), and (103.45 mV), respectively. The effluent is oxidizing and acidic at room temperature. In addition, this effluent is highly charged in COD and BOD5 with respective average values (39150 mg O2 /L), (11930 mg O2 /L). The effluent is, therefore, acidic, oxidizing, and abiotic. Such effluent is a source of hydrogen sulfide and sulfuric acid, highly corrosive pollutants for wastewater treatment plants. These results are, therefore, intended to sensitize involved actors about the need to improve sanitation and regulatory practices in the cosmetics sector.References
