A sand filter is a type of water filtration system that uses sand as a filtering medium. It is commonly used in swimming pools, aquariums, and water treatment plants.
The sand filter works by allowing water to pass through a layer of sand, which traps and removes impurities and particles from the water. The filtered water is then collected and returned to the pool or other water source.
Sand filters come in various sizes and capacities, and the size of the filter required depends on the volume of water that needs to be filtered. Some sand filters also use additional filtering media such as gravel, anthracite, or activated carbon to enhance the filtration process.
Overall, sand filters are an effective and affordable option for water filtration and are commonly used in various applications. They require regular maintenance, including backwashing the sand to remove accumulated debris and replacing the sand periodically.
