A dual media filter is a water filtration system designed to remove suspended solids, turbidity, and contaminants using two layers of filtration media, typically anthracite coal and sand. The anthracite layer, being lighter and coarser, traps larger particles, while the finer sand layer captures smaller impurities, ensuring efficient filtration and longer run times between backwashing cycles. These filters are widely used in water treatment plants, industrial processes, and wastewater treatment applications to improve water clarity and quality. Regular backwashing and maintenance are essential to prevent clogging and ensure optimal performance over time.
