Garnet Sand as Filter Media

The garnet filter is manufactured from chemically stable natural silicate mineral garnets, with a garnet mineral content of ≥ 95%, a tan color, light yellow-green color, a specific gravity of 3.6-3.8, and a capacity of 2.0-2.2. The garnet filter has stable performance and low price, and can replace the expensive manganese sand diamond sand filter and other imported raw materials. The garnet filter is widely used in petroleum and water treatment industries.

Filter garnet is used in the highest specification multi layer multi media filters. The decreasing grain size from the top layer of anthracite through the sand layer to the bottom layer of garnet produces the ideal conditions for high filtration rates and long filter runs.

Filter Media Garnet Advantage

*High specific gravity provides unique filter design. It’s an excellent support bed.
*Garnet, in combination with other filter media, provides higher flow rates, loading and better filtration
*High hardness reduces attrition and extends the life time of the filter bed and provides for years of reliable service.

Garnet is a high hardness, high density granular filter media. It can be used extremely effectively as the lower strata in a dual media filter bed. Its high specific gravity as well as its acid endurance and abrasive resistance makes garnet ideal for filtration.

Due to its large proportion of iron-aluminum-garnet, it does not contain organic matter and soluble acids and therefore has advantages in filtering urban water. It can compete with silica sand, ilmenite, magnetite, etc. from cost, durability and effectiveness.

The garnet used for single-media filters in swimming pools uses one or two different types of garnets; garnets can also be used in multi-media industrial filtration systems. The so-called multi-media namely garnet – quartz, garnet – sand – anthracite and so on. The particle size of these materials is controlled so that they are differentiated according to the specific natural gravity, forming a number of horizontal layers that are coarsely tapered from bottom to top. This medium removes floc from the water.

Advantages of the Garnet filter media

1.Garnet Has good acid resistance and wear resistance;
2.Garnet has good chemical stability;
3.Garnet filter media is Ideal supporting layer;
4.Better filtering velocity, adsorption and filtering efficiency;
5.High mechanical strength and long service life;
6.High melting point and large proportion.
