Product Description

Deep Bed Multimedia Filters For feed water turbidity Removal

Multimedia Sand Filters
Following multi-layer filtration, Multimedia Sand Filters are most recommended systems to remove suspended particles, color, odor and iron from ground water and wastewater. Multimedia filtration works on pressurized filtration process, where three layers of filter media are used for fine particle removal approximately 5 to 25 microns. As compared to conventional sand filters, multimedia filters offer superior filtration quality, longer filtration cycles and lower water consumption during backwash; hence, these filters offer a flexible and feature-rich way to reduce the amount of suspended solids and turbidity in feed water. These multimedia filters are mostly used as pretreatment to reverse osmosis, DM and softener.



Working Principle
 
Also refers to multi-layer filter, a typical multimedia filter contains three layers of filter media (anthracite coal, sand and garnet). The principle behind using these three types of filtration media is the difference between particle size and density properties of these materials. Anthracite media is the lightest and largest particle size media, which remains of top following backwash while the intermediate size media (sand) will settle in the middle and garnet, the heaviest but having the smallest particle diameter, will settle to the bottom. Periodically backwashed is mandatory to remove contaminants trapped in the media during filtration process.

 Most frequently used filtration fillings:
Fine gravel: 1-20mm
Silica sand of various roughness: 0.4-2.5mm
Active charcoal: is used for absorption of chlorine and other mineral substances
Anthracite: is used in two-layer or multi-layer filtration of drinking water in connection with sand - the addition of anthracite guarantees a longer filter lifetime, it facilitates a larger filtration through-flow and reduces sand contamination


The filtration bed can be formed by one layer or more layers of various filtration materials. Filtration sand lifetime during a proper washing of filters oscillates around 8 years on a standard basis.

Filters are controlled manually [with ball valves / shut-off valves] or automatically. In the case of an automatic filter control process, membrane or hydraulic or pneumatic valves are used.


The entire automatic process of filtration and back washing of filters is controlled by a central control unit. The control unit makes it possible to set filter washing on the basis of time, pressure difference or filtered water quantity.
 
Filters are washed, on a standard basis with raw water or with treated water from reservoirs.
 
Filters are fitted with a filtration inter-bottom with jets. The jets are made of the ABS material and make it possible to wash with water or both water and air. In the case of the filling height not exceeding 1500 mm, the water flushing process is fully sufficient.
 
Pressure filters are made of carbon steel with a protective anticorrosion coating with epoxy resin in the RAL 5010 [gentian blue] or 5012 [light blue] colour shade. The coating meets the conditions of hygienic harmlessness for contacts with drinking water.
