sand filter

A sand filter is a device used to remove impurities from water. It consists of a container filled with layers of sand, where water passes through. As water flows through the sand, particles, debris, and some microorganisms are trapped, leaving cleaner water to exit at the bottom. Sand filters are commonly used in various applications, such as swimming pools, drinking water treatment, and wastewater management. They are effective, natural, and low-maintenance solutions for improving water quality. Overall, sand filters help make water safer and more pleasant for human use and the environment.
