How it works

The Filter-Ag granules have fractured edges and non-uniform surface which provide large filtration surface.

In the filtering process water enters the filter vessel, passes through a layer of media, which detains mechanical impurities (sand, rust, silt, etc.)

When contaminants “clog” the free space of the material, the pressure drop in the filter increases and the productivity drops. In this case, the Filter-Ag is flushed and back flushed with a reverse flow of water. After it, the filter is ready to purify the water again.

Application

Filter-Ag can remove particles having a size of 20-40 microns (sand, silt, etc.).

The structure of the granules is heterogeneous, which contributes to a more active retention of particles, including iron in low concentrations.

Consumers

Used in water purification pressure and gravity filters. Thanks to its density, Filter-Ag can also be applied in multimedia filters, incl. sediment filters.
