| Scope note: | In direct descending filtration, the filtering medium can be made either of a single material (single layer) which is also usually made of sand, or of different materials (multiple layers). The most common example of multilayer filters is the double layer filter, usually consisting of anthracite and sand. (Adapted from https://bit.ly/3iWqTTZ) |
