Filter Material

WBG provides filter materials for mono-layer or multi-layer filters. The filter materials are selected specifically for your application. Our special requirements on materials (hardness, resistance to abrasion and granulometry) will secure stable operation for the entire lifetime of your plant.


Materials of different density and grain size are combined in multi-layer filters. For selection of the appropriate filter materials, we take into account the parameters: height of filter material layer, penetration depth, head loss and water quality required.
