Filter-Ag is a filter media based on non-aqueous silica dioxide. It is designed to reduce contents of suspended particles in water.
Technical data
- Color - up to light gray to white
- Bulk density - 0,38‒0,42 kg/dm³
- Real density - 2,25 kg/dm³
- Effective bead size - 0,67 mm
- Uniformity coefficient - 1,8
- Particle size - 0,6–1,7 mm
The operating parameters
- Max. feed eater temperature +60 °С
- Media layer high - 600–900 mm
- Free space in the filter - at least 50% of media
- Linear filtration rate - 12 m/h
- Linear flushing rate - 20-24 m/h
- Expansion layer backwash - 20-40% of media
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.
