Multi-media filter is a typical multi-media filter with layered anthracite, sand, finely crushed garnet or other materials as the bed layer.
The equipment is pressure type, and its principle is that when the original water passes through the filter material from top to bottom, the water suspended matter is retained by the surface of the filter layer due to adsorption and mechanical flow blocking; when the water flows into the middle of the filter layer, as the sand particles in the filter layer are arranged more closely, so that the water particles have more chances to collide with the sand particles, so the water coagulation, suspended matter and sand surface adhere to each other, and the impurities in the water are retained in the filter material layer, thus Clarified water quality is obtained. The suspended matter in the filtered water can be below 5 mg/l.
