  • Abstract: We chose this topic because many people around the world get diseases such as diarrhea and cholera due to unhygienic water and die due to it. Dirty water is passed through a carbon filter and then a silica filter to remove solid materials and improve clarity, smell, and taste in a small scale filtration system. For visualisation, the water is placed in a bucket with a pump to push it through the sand filter to create water with fewer solid materials that is not suitable for drinking. However, the next step is to disinfect the water to kill any germs and viruses.
