Dual Media Filters | Fluid System
The Dual Media Filter utilizes combination of Filter Media and Anthracite for higher flow rates with a smaller footprint. High filtration velocities are achieved by proper selection of Media, and designing of Distribution and collection systems. These filters are offered in Mild Steel, FRP or SS construction with face piping and associated Valves.
Granular Activated Carbon Pressure Filters
Media options and arrangements are several and depend on the application and internal piping arrangement but often consist of a dual-media, sand-and-anthracite arrangement (to minimize backwash frequency) above a gravel support bed.
Filtration - MRWA
filter water with an average turbidity of less than 25 NTU. Dual and multi-media filters are used with direct filtration. They are able to remove more suspended material per cubic foot of filter media than sand filters. Direct filtration plants have a lower capitol cost. However, the process cannot handle large variations in raw water turbidity.
Multimedia Filtration | Multi-Media Water Filters
Pressure vessels with sand or other loose media are widely used in industrial filtration applications. During the cleaning cycle, called “backwash”, the bed is lifted (or “fluidized”) to loosen the filter media and release trapped dirt which is removed in the backwash flow.
