Multimedia Filtration (MMF) Multimedia filtration is a modern physical water treatment technique that uses at least three different layers of filtration media, typically anthracite, sand and garnet, to filter water.
In some cases, physical state is changed, as in vaporization, and often dispersed substances are caused to agglomerate, as happens during filtration. Physical methods of wastewater treatment include sedimentation, flotation, and adsorption, as well as barriers such as bar racks, screens, deep bed filters, and membranes.
