Water Filtration Through Fly Ash, Sand and Charcol Filter

Abstract

This project focuses on the implementation of a sequential filtration system using fly ash, sand, and activated charcoal filter beds to treat contaminated quarry water and contaminated cleaning water from a rubber factory The goal is to diminish the concentrations of diverse contaminants found in the wastewater and enhance its overall qual The goal is to diminish the concentrations of diverse contaminants found in the wastewater and enhance its overall quality. ity. To begin, the project involves the collection and characterization of the wastewater samples, including parameters such as pH, chloride, biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity, hardness, dissolved oxygen, and conductivity. This step provides a clear understanding of the initial contamination levels and aids in the evaluation of the filtration system's effectiveness. Ensuring the availability of the necessary filter media, namely fly ash, sand, and activated charcoal, is another important aspect. These materials are chosen for their filtration properties and compatibility with the wastewater being treated. The filter beds are then prepared, taking into consideration the appropriate sizing and arrangement of the filter media. Subsequently, the wastewater undergoes treatment using the sequential filtration process. The water flows through the fly ash bed, where larger particles and impurities are initially removed. It then moves on to the sand bed, which further removes suspended solids and finer contaminants. Finally, the water passes through the activated charcoal bed, where organic compounds and residual contaminants are adsorbed, resulting in further purification. After treatment, the characteristics of the treated wastewater are evaluated and compared to the initial values. The results reveal a significant reduction in parameters such as COD, BOD, pH, chloride, and turbidity, indicating the successful removal of contaminants through the filtration process. Overall, this project demonstrates the effectiveness of the sequential filtration system using fly ash, sand, and activated charcoal filter beds in reducing contamination levels and improving the quality of the wastewater. The findings suggest that this filtration approach holds promise as a potential solution for wastewater treatment in various industrial and environmental applications.
