Industrial Mechanical Sand Filter For Water Treatment ...
A multi-media filter is a layered bed containing anthracite, quartz sand, activated carbon or other fine particles. The principle is that when the raw water passes through the filter material from top to bottom, the suspended matter in the water is intercepted by the surface of the filter layer due to adsorption and mechanical blockage.
