“How can we use sand to filter water?”

Sand has many wonderful properties. People can use some of these aspects to filter water. Sand’s small pore size makes it easy for large particles to get trapped, stick to sand particles, or settle down from low velocity. So what if we were to fill a filter with sand, pump water onto the top of the sand bed, and then place pipes near the bottom of the sand to catch the cleaned water at the end of the journey? Well, this is the main idea behind Sand Filters. Sand filters are an excellent way to filter water for your purposes. Some sand filters require backwashing to operate
