A multi-media filter utilizes two or more filtration media (e.g., anthracite, quartz sand) layered with decreasing particle size from top to bottom. It effectively removes suspended solids, colloids, silt, rust, and larger particles through depth filtration principles. It is commonly used as essential pretreatment for precision systems like reverse osmosis and ion exchange, reducing feedwater turbidity and SDI to protect downstream membranes or resins.
