We are Largest manufacturer and supplier of Dual Media Filters. We mainly manufacture FAB Technology based Dual Media Filters.These are constructed using high grade raw material, which is procured from most trusted & reputed vendors of the market. Robustly constructed, defects-free, finely finished & rust resistant range of these premium quality is available in different standard sizes as well as customized as per the specifications of our valued customers.
Dual Media Filters are employed for the removal of turbidity, suspended solids and some part of odor and color from Water & Waste-water. We offer filters at at reduced cost, reliable and highly efficient way to filter the water.
Our unique designing of Dual Media filter insures the maximal usage of the surface area, little pressure drop across the filter beds and effectual separation of the wastes even under the states of higher filtration rate in comparison with pressure sand filter.
Our DMFs are accessible in diameters from 0.225 Mts. to 4.0 Mts.(vertically) as well as in length from 3.0 Mts. mm to 11 Mts. (Levelly) with flow rationgs up to 400M3/Hr. These sturdy, pre-assembled, pre-engineered, units minimize installation and start-up costs. Whether you need filtered water or RO feed process water we can efficiently fulfill applications requirements.
Raw water is processed through the dual-media filters, comprise anthracite along with fine sand made by gravels and marbled. These filters have a coat of anthracite (1.25-2.5mm) resting on a finishing of fine sand (0.6-1.5mm) Anthracite is coarse-grained substance that has more dirt holding capability in comparison with fine sand.
During the filtration interval the largest molecules are forced out by the anthracite. After this the sand traps the remainder of the particulate matter though an accumulation of straining and adhesion. Since the materials in the water are filtrated at different depths in a duple media filter, the filter does not block as speedily as all of the materials were caught by the top level.
