Summary: Phosphate-loaded industrial wastewaters have caused significant environmental issues in the Gulf of Gabes-Tunisia. This study compared the phosphate adsorption capacities of two types of Tunisian activated clays and optimized the phosphate removal efficiency using response surface methodology. The results showed that both activated clays demonstrated high adsorption capacities and could be considered as a cost-effective and efficient alternative for phosphate removal from industrial wastewaters.

Summary: The potential use of sewage sludge as a precursor for activated carbon production was investigated, and its performance was compared with a commercial activated carbon for Bisphenol A removal from synthetic solutions. The study focused on the impregnation ratio and the use of CO2 during carbonization to optimize the textural properties and adsorption performance of the activated carbon. The prepared activated carbon showed excellent adsorption efficiency for Bisphenol A, and the best conditions achieved were applied for the removal of Bisphenol A from real effluents, showing promising results.

Summary: In this study, a low-cost and environmentally friendly sludge-based adsorbent modified by calcium oxide (CaO) was prepared. The CaO modification was found to enhance the adsorption capacity and mechanical strength of the adsorbent. Optimal conditions for Cd(II) adsorption were identified as 5% CaO dosage and 60 degrees C drying temperature, with a Cd(II) adsorption rate of 99.74% achieved under these conditions.

Summary: In this study, potassium was tested as a novel washing agent for cesium-contaminated soil. Response surface methodology combined with a Box-Behnken design was used to determine the optimal washing conditions. The results showed that a potassium concentration of 1 M, a liquid-to-soil ratio of 20, a washing time of 2 h, and a pH of 2 achieved the highest cesium removal efficiency of 81.3% in field soil contaminated at 1.47 mg/kg.

Summary: This study optimized the operating conditions for coagulation-flocculation line sizing using BBD, achieving high turbidity removal and low residual metals concentration. The results showed that FeCl3 was the best coagulant, with optimal parameters including coagulant dose, stirring time, and stirring velocity. The obtained R-2 values indicated a good model fit for turbidity removal and residual iron concentration. The findings could be scaled up for application in desalination plants, highlighting the potential of the BBD approach for predicting response values without experiments.
