Water Media Filters | Industrial & Commercial

Pressure Media Filters

Wigen is a leading producer of custom-built pressure filter systems for a wide variety of industrial and municipal applications. Pressure filters utilize a process in which, a pressurized fluid stream contacts granular media for physical and/or chemical removal of impurities. We design our pressure filter systems to ensure the right media products are used to meet the client's desired effluent and waste stream requirements. Often we are able to incorporate our patented reclamation technologies to greatly reduce the amount of waste water produced from normal backwash operations.

UAE Water Filters 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 deionization systems or as a pre-treatment system prior to a disposable bag or cartridge filters.


The multi-media water filter systems operate for much longer periods of time (five or more times as long at the same filtration rate) before backwashing is necessary because the bed can hold more turbidity. Turbidity is trapped and held throughout the entire bed depth, rather than the top one or two inches.

Multi-media filtration is much better suited for use in a closed pressure tank since cracking of the bed, and subsequent breakthrough of turbidity is virtually eliminated and the need for visual inspection is unnecessary. The use of pressure tanks (rather than open basins or filters) is an obvious advantage for point-of-use filtration and could also be of real importance in the filtration of small community water supplies. More rapid filtration flow rates in multi-media filtration allow the use of smaller diameter tanks with equal or better results. A very high degree of clarity is achieved in the filtered water because of the fact that the finer particles of garnet at the bottom trap finer turbidity particles.

What is media filter in water treatment?

Multi media water filter systems use three media layers for multimedia filtration. These layers are called anthracite, sand and gravel. Their usefulness resides in the distinct differences in density between these layers of media. Anthracite has the least density among the three, followed by sand, and gravel.

Benefits of multi-media filters?

While conventional sand filters are composed of only one filtration media, media filters consist of multiple and are ordered in descending entrances. Due to their greater amount of layers, multi media water filter systems are capable of capturing and holding a superior number of fragments than conventional sand filters before backwashing is needed. Additionally, multi media water filters function for an extended amount of time in comparison to traditional sand filters, since they are able to trap sediment and particles throughout the entire filter bed. This filtration process creates cleaner water much at a much faster rate than conventional sand filtration. The media filter comes complete with 5 valves and automatic controller to accomplish the backwash cycles.
