Abstract

The types of silica that can be obtained from the rice husk waste product included crystalline and amorphous silica. Since the process to obtain the amorphous silica is much more energy-saving than crystalline silica, this study is fully utilizing the amorphous silica to produce the silica water filter. Meanwhile, for the preliminary studies will be conducted by using synthetic silica. In light of that, this study aims to produce amorphous silica from rice husk waste product that can be obtained from the area of Pasir Puteh and Pasir Tumboh, Kelantan. Other than that, this study also aims to fabricate the silica water filter by using the Slip Casting method, and next, investigate the physical and mechanical properties of the developed silica water filter. In this study, the method that will be used to fabricate the silica water filter Slip Casting method. For the preliminary studies of this research, the synthetic silica will be used to test the work rate of the mould for the method mentioned. After the fabrication process, the silica water filter will undergo several testing processes. The testing processes consists of Scanning Electron Microscope (SEM), shrinkage analysis, porosity analysis, density analysis and water absorption analysis. Under this research, amorphous silica with very low residual carbon content (approximately 1.0wt% residual carbon) was successfully being produced. The optimum freeboard height to prevent sand contamination and to achieve complete carbon burnout in the silica rice husk was found to be at least 5000mm. The obtained results indicate that the Slip Casting method can be used to produce the silica water filter. The water that have been flown through the silica water filter have been observed from time-to-time. This shows that the silica water filter has successfully absorbed the unwanted contaminants and change the colour of the water from muddy colour to a clear colored water. In conclusion, the different silica composition and temperature used greatly influence the rate of porosity, density and water absorption of water filtration. For the suggestion of this study, hopefully this research study can have the continuity to have a deeper and more precise case study so that this research study can produce a more effective and efficient silica water filter to help those in needs.
