A media filter is a type of filter that uses a bed of sand, peat, shredded tires, foam, crushed glass, geo-textile fabric, anthracite, crushed granite or other material to filter water for drinking, swimming pools, aquaculture, irrigation, stormwater management, oil & gas operations, and other applications.

As particles become trapped in the media, the differential pressure across the bed increases. Periodically, a backwash may be initiated to remove the solids trapped in the bed. During backwash, flow is directed in the opposite direction as normal flow. In multi-media filters, the layers in the media re-stratify due to density differences prior to resuming normal filtration.

De.mem offers a wide range of media filters for all common applications in municipal and industrial water filtration. De.mem also supplies the required media for replacement.
