Abstract

Providing clean and safe water has become a staggering challenge due to the increasing demand for clean water supply. In this research project, a multimedia filtration system with silica sand, activated carbon, and zeolite as the filter media will be used to treat the water sample, which is rainwater mixed with clay soil. From the study, the results indicated that configuration 2 with a higher total mass of 800 g which consists of 5% Zeolite, 5% Activated Carbon, 70% Silica sand of 2.3 mm, and 20% Silica sand of 0.6 mm produce the best results for all water parameters. This is because the increase in the total mass of filter media will also increase the efficiency of the filtration process as it increases the surface area of the filter media in contact with the particles of contaminant. Meanwhile, concerning the configurations of the same total mass of 400 g, configuration 5 gives the highest reduction of contaminants. This is due to the higher portion of Zeolite and Activated Carbon compared to other configurations of the same mass. Configuration 5 consists of 20% of Activated Carbon and Zeolite, while configurations 1,3, and 4 consists of 5%, 10%, and 15% of Activated Carbon respectively. Hence, a higher proportion of filter media with high adsorption capacity are more effective compared to other configurations considering the low filtration rates. Moreover, it is found that filtration at the lowest flow rate could achieve the maximum removal of polluting contaminants. Hence, three important aspects must be considered for the implementation of the multimedia filtration system which includes the configuration of filter media, the total mass of filter media, and the filtration flow rate. A new design of a multimedia filtration system and some recommendations are proposed to overcome the limitations of the filtration system used in this study.
