| description | The objective of this research is to enhance the elimination of humic substances found in agricultural drainage water using a two-fold approach: coagulation-flocculation using aluminum sulfate both separately and in combination with powdered activated carbon made from prickly pear skin. To attain our goal, laboratory jar test were conducted on synthetic solutions. Several reaction parameters were examined, including the impact of changing coagulant dosage, impact of temperature, and adjusting pH levels. The results obtained demonstrated that the flocculation process is more effective in reducing compounds with higher molecular masses. Compared to a 49% removal rate with aluminum sulfate alone, the addition of an adjuvant powdered activated carbon made from the skin of prickly pears greatly improved the elimination process, resulting in removal rates of 92%, 84%, and 79% for powdered activated carbon masses of 0.50 g/L, 0.20 g/L, and 0.10 g/L, respectively. Throughout this investigation, we will showcase the outcomes derived from the tests performed on synthetic solutions containing model organic compounds (commercial products) dissolved in distilled water, alongside the analysis of agricultural drainage waters. The study investigates the influence of various reaction parameters on the removal efficiency of humic substances through coagulation-flocculation using aluminum sulfate. The results show also that in the presence or in the absence of powdered activated carbon derived from the skin of prickly pear, the coagulation is more eficient at low pH (5 to 6). In addition, we have show that simple coagulation flocculation remove only 66% of Chemical oxygen demand (COD) of initial value and the presence of powdered activated carbon (40 mg.L-1) increases efficiency up to 82%. To enhance this process, the addition of a water additive is considered to improve treatment efficiency. |
