Summary: This study investigates the treatability of leachate from hazardous waste landfills through electrocoagulation. The results show that electrocoagulation can effectively reduce the chemical oxygen demand (COD) of the leachate by up to 90% under optimized conditions. Significant reductions in other parameters were also observed. The findings suggest that electrocoagulation can be a viable alternative to energy extensive treatment technologies for managing leachate from hazardous waste landfills.

Summary: This study investigated the feasibility of using biological and electrocoagulation treatment systems in poultry slaughterhouse wastewater treatment. The response surface methodology was used to determine the optimal operating conditions for electrocoagulation and its integration with a biological pretreatment. The results showed that electrocoagulation outperformed the biological method alone, but there was no significant difference when both methods were combined. Additionally, the novel pretreatment method, Ecoflush(TM), proved to be highly efficient in removing fats, oils, and grease from the wastewater.

Summary: The study aims to design and optimize a full continuous combined process based on electrocoagulation-adsorption to treat real textile effluent using Tunisian clay. The characterization of the clay confirms its suitability for the process. The response surface methodology (RSM) was used to optimize the process parameters, and the achieved removal efficiencies for color, COD, and TSS were satisfactory, accompanied by a reasonable cost. The results of additional laboratory experiments validated the accuracy and capability of RSM for predicting outcomes in defined conditions. The designed process offers an environmentally friendly and cost-effective alternative for treating and reusing wastewater in industrial processes.

Summary: In this study, wastewater from the Antibiotical-Saidal pharmaceutical plant was pretreated by coagulation-flocculation using copper sulfate (CuSO4), iron chloride (FeCl3), and a mixture of the two salts. Response surface methodology (RSM) and Gaussian process regression coupled with the dragonfly optimization algorithm (GPR-DA) were employed to optimize the treatment process and predict the reduction rates of dissolved organic carbon (DOC), absorbance at 254 nm (UV 254), and turbidity. The results showed that the mixed coagulant (CuSO4 + FeCl3) achieved superior treatment efficiency compared to using CuSO4 or FeCl3 alone.
