Media Filtration Multi-Media Filtration Water ...

Multi-media (multi-layer) Filtration. Multi-media filters consist of several layers—usually three to five—of different media. The media are loaded by density—the densest in the bottom of the tank, the least dense on top. This produces a filter with an excellent flow rate and relatively easy backwash properties that will filter down to ten ...

filter water with an average turbidity of less than 25 NTU. Dual and multi-media filters are used with direct filtration. They are able to remove more suspended material per cubic foot of filter media than sand filters. Direct filtration plants have a lower capitol cost. However, the process cannot handle large variations in raw water turbidity.

Filtration Processes IWA Publishing

Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth
