Several regions in the world are facing the risk of water scarcity due to arid climatic conditions or resource contamination by metallic pollutants generated by anthropogenic activities. This situation is a significant threat to the agriculture industry. Slow sand filtration has been recognized as an effective and sustainable approach to decontaminating water contaminated by heavy metals. This study aims to present a general modeling approach of slow sand filtration process, with a focus on the removal of heavy metals from contaminated water for irrigation purposes in the Draa Sfar region in Marrakech - Morocco. This article outlines the theoretical basis of the modeling approach, including the kinetics of heavy metal removal and the role of adsorption mechanism of sand in the filtration process. The model considers various parameters: contaminated water (C), adsorbed water (A), diffused water (D) and filtered water (F). The simulation results indicate that slow sand filtration can achieve a high degree of heavy metal removal. The model can also predict the breakthrough point, which can be used to optimize the filter design and operation. The findings of this study suggest that slow sand filtration can be an effective and sustainable approach for decontaminating water contaminated by heavy metals in the Draa Sfar mine region, providing safe irrigation water for agriculture. |
