Answer Details
During water treatment for town supply, water is passed through layers of sand beds in order to filter the water. The sand beds act as a physical barrier that separates large particles, sediments, and debris from the water. As the water flows through the sand bed, the sand traps the suspended particles, and clean water passes through. This process is called filtration and is an essential step in water treatment, as it removes impurities and improves the quality of the water. The filtered water can then be treated further to remove any remaining impurities or disinfect it to kill any harmful bacteria and viruses.
