The media layers are stacked progressively with the coarsest and densest media, typically gravel, at the bottom and the lighter, finer media, at the top. The filter media is usually 15 to 30 in. A backwash should be performed when the differential pressure is greater than 10-15 psi. For dual-media filters, the top anthracite layer has an effective size of 0.8-1.2 mm, a uniformity coefficient of less than 1.85, thickness of a few inches to two thirds of the total filter thickness of 24-30 in., and is underlain by a sand filter layer as described above. Multi-Media Filters contain several types of media … SDI less than 3? This produces a filter with excellent flow rate and and relatively easy backwash properties that will filter down to ten microns. Filtration Media (Replacement Media for Media Filters) AMI carries a large range of filtration media and support media to be used in most types of media filtration systems. Activated Glass Filtration Media replaces traditional sand media in all filtration applications. The backwash flow rate must be high enough that the media becomes de-compacted and expands by 40-50%. The settle phase should be seriously considered by those in places where access to water is scarce. 5µ nominal rating. Multi media filtration is a proven design concept; the coarse media layers in the top of the tank trap large particles, and smaller particles are trapped in the finer layers of media deeper in the filtering bed. Those are the ingredients you're getting, if you're buying a replacement load for a conventional filter. Iron reduction? As the  ), Contact us ), are used for closely controlled coagulation and sedimentation. 99. Multi-media water filters are able to trap and retain a far larger number of particles (generally down to 10-25 microns) than traditional sand filters … Principal of Operation – MultiMedia Filters. Multi media filters use graded support media layers over the under-drain to prevent the layers from migrating into each other during backwashing. This gives the media time to compact itself to give more efficient filtration performance before the filter goes into service. At this time the media is considered to be fluidized and acts more like the water flow than the solid filter bed. During the settle phase, the filter closes and no water flows in or out. The recommended backwash flow rate is 12-15 gallons per minute per square foot, which enough to lift the media bed sufficiently without forcing any media out of the top of the filter. Media filters have the advantage over other types of filters in that they have the ability to be ‘backwashed’. Conventional pressure rapid filters operate in a down-flow direction, during service flow operation, influent water to be filtered enters at the top of the filter, percolates through the filter bed, and is drawn off through the collector or the distribution system at the bottom. At 24 pounds per cubic foot it sits as the top layer in a multi-media filter. That is to say that any particle larger than the collective effect of the media particles will be separated from the water.
