Laminar Water - Model MMF -Multimedia Filtration System

Multimedia filtration uses a media mix of engineered sand, anthracite and larger structural media to provide filtration for removal of impurities from water. This technology, also referred to as rapid sand filtration, is simple and reliable and allows removal of suspended solids, pathogenic organisms and some organic macromolecules. MMF uses a reverse-graded, dual-media bed. A top layer of larger, less dense anthracite sits above a lower layer of smaller, denser sand. As water flows downward, the largest particles are captured in the coarse top layer, while progressively smaller particles are removed by the finer sand layer below. This design utilizes the entire depth of the filter bed for solids storage.
