Filter-Ag is a filter media based on non-aqueous silica dioxide, and designed to reduce contents of suspended particles in water. Used in water purification pressure and gravity filters. Thanks to its density, Filter-Ag can also be applied in multimedia filters.

Key advantages:

  • low pressure loss at the Filter-Ag bed compared to other filter media

  • light weight reduces water consumption during backwash

  • high efficiency results in lower expenses related to the equipment

  • high sediments reduction capacity leads to longer service life of the media

  • replacement of sand with Filter-Ag increases filter capacity by 100% or more

The Filter-Ag granules have fractured edges and non-uniform surface which provide large filtration surface. High efficiency is achieved in reduction of suspended particles sized more than 20-40 micron.
