Dual Media Filter - Manufacturers, Suppliers & Exporters
SHUBHAM INC. Manufacturer,exporter,trader,supplier of all type of sewage treatment plants, effluent treatment plants, India best quality sewage treatment plants manufacturers from Ahmedabad, send requirement detail of Dual Media Filter, sewage treatment plants and effluent treatment plants etc.Dual Media Filter contain anthracite along with fine sand reinforced by marbled and gravels. These filter consist of a coating of anthracite (1.25-2.5 mm) resting on a coating of fine sand (1-1.5 mm) 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 back washing 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
