Dual media filter contain anthracite along with fine sand reinforced by marbled and gravels. These filter consist of a coating of anthracite (1.25-2.5mm) resting on a coating of fine sand (1-1.5mm) Anthracite is coarse and has more dirt holding capacity as compared to fine sand. Dual media filters are used in places where the raw water contains suspended contaminants, turbidity and iron. Dual media filters provide very efficient particle removal under the conditions of high filtering system amount. These filters use layers of anthracite and garnet contaminants as the filter medium, with filtering system amount of 98% down to 2 microns. The dual media filters employ an automatic backwashing feature, which employs a variety of air and water to maintain unit efficiency. Working Principle: The media in a dual or multi-media filter are arranged so that the water moves through media with progressively smaller pores. The largest particles are strained out by the anthracite. Then the sand and garnet trap the rest of the particulate matter though a combination of adhesion and straining. Since the particles in the water are filtered out at various depths in a dual or multi-media filter, the filter does not clog as quickly as if all of the particles were all caught by the top layer. Advantages and Features Efficient Turbidity and TSS Removal Filter up to 20 – 30 Microns FRP, CS, MSEP, SS Vessel available ASME Pressure Vessel is also available Two, Three and Multi layer filters Low Pressure drop across the vessel Air scouring available for high flow pressure vessel Manual, Semi Automatic and Automatic features are provided Long filter cycles between backwashing with minimum loss of pressure. Pneumatic and electrical operating automatic valves Two elliptical manholes Hand-holes Automatic control and electrical cabinet. Salient Features: Dual media filters have high dirt removal capacity of the finest sand forms Dual media filters are five times more effective in removing dirt than the pressure filters Dual media filters provide very efficient particle removal under the conditions of high filtration rate. Inside a sand-anthracite filter is a layered bed of filter media Sand is used to remove the suspended particles and anthracite is used to remove the odour and colour etc. to make the water fit for different applications It also cocks-up with existing benefits of PSF and ACF Applications Drinking water filtration Effluent water filtration Swimming pool filtration Processes water filtration To remove turbidity from water For pretreatment of reverse osmosis & desalination system To remove and minimize suspended particles from the water

Dual Media Filter (DMF) : Dual Media Filter primarily used to Filter out Turbidity in the raw up to level of 50 NTU.It consists of of sand and Anthracite as Filtering Medium, Anthracite having higher dirt holding capacity is used for removing turbidity. Activated carbon Filters (ACF) : Activated carbon Filters consists of charcoal which is used as a media for removal of Free Residual Chlorine, Colour,Odour and Oil in small quantity. Pressure Sand Filter (PSF) : Fine mesh sand along with gravel of different sizes are used as the filtering Media. It is used to filter out turbidity from Raw Water up to level of 25 NTU.
