A multi-media filter is an efficient filtration device that uses one or several filtering media to pass high turbidity water through a certain thickness of granular or non granular materials under a certain pressure, effectively intercepting and removing suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions in the water, ultimately achieving the effect of reducing water turbidity and purifying water quality.

Common filter media include quartz sand, activated carbon, high – quality magnets, tree bark, mineral balls, and so on. Widely used in various industries such as chemical, petroleum, metallurgy, and mining.

The multimedia filter equipment has the characteristics of simple structure, automatic control during operation, large processing flow rate, few backflushing times, high filtration efficiency, low resistance, and easy operation and maintenance.
