Product Description

high-bed (multi)media filters have a filter bottom with removable filter plugs. The raised filter bed results in more contact time with the medium, which provides the possibility of achieving higher capacities. In addition, it is possible to use more layers as a filter medium, which increases capacity and/or enhances quality. These filters are provided with enough manholes to allow for easy inspections and changing of the filter material. All models can be modularly joined, in conjunction with appropriate flush valves, to form units of any shape and capacity and for continuous service. To this end, a comprehensive range of fittings, connectors, and rapid couplings of the same make is available.



Pressure Sand Filter offered by us is used for water purification processes for different types of water like river water, lake water, bore well water filtration and others. For delivering optimum performance, these pressure sand filters consist of a pressure vessel that can be either vertical/ horizontal-fitted with a set of: 

Description:


Frontal pipe work and valves
Graded silica quartz sand that is supported by layers of graded under bed consisting of pebbles & gravels
Distributor to distribute incoming water uniformly throughout the cross section of filter
Under drain system to collect filtered water

This product generally also known as:

Applications:
 
Pre-filtration of disinfection equipment
Preparation for micro and ultrafiltration
Swimming pool filtration
Groundwater purification
Separation processes in which flocculants are used
Water treatment plants
Suitable for various filter media (active carbon, neutralisation media)


 
 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.
 
This kind of arrangement allows the largest dirt particles to be removed at the top media bed and the smaller and smaller dirt particles being retained deeper and deeper in the media. This down-flow filtration permits delivery of high quality filtered water at much faster flow rates; typically particle removal approximately 5 to 25 microns.
