Commercial Multimedia Filters have a higher retention capacity than conventional sand filters, and currently represent the most widely used optimal option for removing sediment, mud, silt, oxides, and suspended solid particles down to levels of 15-5 microns<\/em><\/strong>.<\/p>\n\n\n\n Multimedia Filters consist of a multi-layered bed with a gravel support. Particle removal is \u201cdeep\u201d since it occurs throughout the entire bed, in all its layers.<\/p>\n\n\n\n Although they are used mostly for commercial applications, they can be used in light industrial applications.<\/p>\n\n\n\n Over time, the bed will become saturated with solids, producing an increase in the pressure drop across the filter and lower water production.<\/p>\n\n\n\n In order to continue operating, the filter will require backwashing, which is carried out by means of an automatic valve located at the top of the container, reversing the direction of flow through the bed.<\/p>\n\n\n\n Automatic backwashing removes the solids retained in each of the layers of filter media and carries them down the drain. This operation usually lasts ten to 15 minutes and must be carried out periodically, by time or volume of filtered water to ensure filter operation.<\/p>\n\n\n\n The automatic Clack valve is standard on SWS supplies, but if you are already familiar with Pentair’s Fleck we carry that option.<\/p>\n\n\n\n For smaller systems the manual valve option is available.<\/p>\n\n\n\n Standard multimedia filter media consists of three layers on a bed of gravel, these are:<\/p>\n\n\n\nApplications of Commercial Multimedia Filters<\/h2>\n\n\n\n
