Water in a dual media filter passes through media with moderately smaller pores. Anthracite exudes out the largest molecules. Next layer removes particles with the help of adhesion and straining combination feature of sand and garnet. Filters do not block as fast as they do in a single filtration process. It is basically due to multiple depths or filters in dual media filter process.
A back washing technique is used in dual media filters that helps maintaining unit efficiency.
Dual filters are more efficient than the normal sand media filters in attracting large amount of particles present in water. This happens because of the many filter layers with different levels of pores.
Another difference noted when compared with the sand media filters is that dual media filters last longer. This is because of the complete utilization of the dual media filter bed. Some more benefits are mentioned below:

These filters are the most popular method for removal of turbidity from water. The Pressure Sand Filter consists of a multiple layer of sand with a variety in size and specific gravity. These Filters are designed to remove turbidity and suspended particles present in the feed water with minimum pressure drop. These Filters are custom designed to suit the process requirement. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.
The Pressure sand filter consists of a pressure vessel either vertical or horizontal, with a set of frontal pipe work and valves, graded silica quartz sand supported by layers of graded under bed consisting of pebbles and gravels, a top distributor to distribute the incoming water uniformly throughout the cross section of the filter, and an under drain system to uniformly collect the filtered water.
Raw water flows down wards through the filter bed and as the suspended matter, which is treated by addition of a coagulant like alum or poly electrolyte, is retained on the sand surface and between the sand grains immediately below the surface. There is steady rise in the loss of head over a period of time and the flow reduces once the pressure drop across the filter is excessive.
The filter is then taken out of service and cleaning of the filter media is effected by flow reversal also called as backwash. To assist in cleaning the bed, the backwash operation is sometimes preceded by air scouring by way of agitation through the under drain system. The air scouring agitates the sand with a scrubbing action, which loosens the intercepted particles. The filter is now ready to be put back into service.
