Dual Media Filter

A sand-anthracite filter or dual media filter/multi-media filter is primarily used for the removal of turbidity and suspended solids as low as 10-20 microns. Dual media filters provide very efficient particle removal under the conditions of high filtration rate.

Features of Dual Media Filters

• Simple design.
• Multi-layer filters.
• 20-30 micron filtration rating.
• Standard and persuasive quartz sand media.
• Air cleaning for high flow pressure vessel.
• Low pressure drop across the vessel.
• Vessels like MSRL, SS, DRP, and MSEP.
• Manual, semi-automatic, and automatic features.
• For safety, structural steel legs are designed which provide strong support.
• Takes care of occasional fluctuations in flow rate.
• Filter cycles between backwashing are long.

Application of Dual Media Filters
Dual media filters are mostly applicable where water is contaminated with turbidity, iron, suspended solids, etc. They are one of the most effective ways to remove impurities under various conditions.

Common uses of dual media filters are in these filtration processes:

Drinking Water Treatment
