Multimedia filter

Water multimedia filter by far is the most common type of water filtration, they contain multi layers of media. Each layer is progressively sized in coarseness and layer depth. 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.


Pressure vessels with sand or other loose media are widely used in industrial filtration applications. During the cleaning cycle, called backwash, the bed is lifted (or fluidized) to loosen the filter media and release trapped dirt which is removed in the backwash flow.

That is to say that any particle larger than the collective effect of the media particles will be separated from the water. MultiMedia filters are essentially particle separators. Visible particles are ~microns.


The above multi-media filtration calculator calculates the diameter of a round multi-media filter (MMF) based on the filter bed speed as input. Dual Media Filter also called as mechanical filter is composed of deep-bed system with multi layers of media in the tank. The major media to be applied in the system of sand and anthracite.


Pure Aqua multi-media water filter systems are ideally suited for use where stringent water quality standards are required or where higher levels of suspended solids are present.

These applications can include re-use applications, water pre-treatment applications for reverse osmosis and. When the filters are loaded with particles, the flow. What is a multimedia water filter? Traditional filter systems use graded silica sand filter media. Multimedia Filters and Depth Filters: Produce filtered water and remove sediment efficiently.


Since the sand grains all have about the same density, larger grains lay toward the bottom of the filter bed and finer grains lay at the top of the filter bed. If the solids are uniform in size and shape, a single filter media can be selected to efficiently remove the particles. Multi-Media Filters (MMF ) are an efficient, economical method for removing suspended solids from a waste stream.


In low TSS streams, they can be used for primary treatment. They are an excellent method of secondary treatment after a primary treatment such as an inclined plate clarifier. AMI carries a large range of filtration media and support media to be used in most types of media filtration systems. Media Filtration is the most effective method for removal of suspended organic and inorganic solids from water.


The media filters operate on the same basic principle as nature’s own ground water filtering process. A wide variety of multimedia sand filter options are available to you, There are 2multimedia sand filter suppliers, mainly located in Asia. The top supplying countries or regions are China, Malaysia, which supply , of multimedia sand filter respectively.

In a water supply system, a bed-type filter containing several different filtration media (e.g., coal, san and garnet). Filter media properties The filter media is characterized by two main parameters:the effective size and the uniformity Effective size of the filter media coefficient. The eff tiffective size of the media is the di tdiameter that of the filter media is less than it size and is denoted as d 10.


They are used in applications such as chlorination filtration systems, general turbidity removal and prior to ultraviolet sterilizers or water softeners.
