sand filter
Granular water cleaner
A sand filter is a water purification device that passes liquid through layers of sand to remove suspended particles and contaminants.
Common in swimming pools, wastewater treatment, and drinking water systems, sand filters trap debris as water flows downward through the granular bed.
They require periodic backwashing to flush out accumulated material.
