What is a sand filter and how does it work?
A sand filter is a type of water filtration system that uses sand as its primary filtering medium to remove dirt, debris, and other impurities from pool water. It operates by directing water from the pool through a pump and into the filter tank, where it passes through layers of sand. As the water flows through the sand, contaminants are trapped in the grains, and the cleaner water is then returned to the pool.
The effectiveness of a sand filter depends on the type of sand used and the size of the filter. Generally, the filter media is specifically designed to capture particles of varying sizes, providing adequate filtration to ensure that pool water remains clean and clear. Regular maintenance, including backwashing and replacing sand as needed, is essential for optimal performance.
