Media Filtration

Media Filtration is the passage of a fluid through media in order to remove matter held in suspension. Filter media are granular filtering materials installed in the filters, to retain the suspended solids during the filtration process. Suspended solids consist of small particles such as silt, clay, grit, algae, organic matter and other microorganisms.

Multi-media water filters are made of three filtration media, ordered in decreasing porosity. They are able to trap and retain a larger number of particles because of their multi-layer design before backwashing becomes necessary.

Trapping sediment and particulates throughout the entire depth of the filter bed, allows multi-media water filters to operate for much longer periods of time than conventional sand filters. The process of multimedia filtration produces high quality, filtered water at much faster flow rates than traditional sand filtration.
