Garnet sand in accordance with EN 12910

EVERZIT® GS is a naturally occurring garnet sand (Almandine). Its high density makes it particularly well suited for use in very fine grain sizes for ultra-fine particulate filtration.

Grain sizes

I)     0.2 - 0.6 mm
II)    0.6 - 1.4 mm
III)   1.4 - 2.5 mm

Other grain-size ranges can be supplied in accordance with your specific requiremants.

Features and Benefits / Applications

EVERZIT® GS is used as the bottom filtration layer in dual media filters. Very high in density, it can be used in very fine grain sizes – i.e. down to 0.2 mm – in wide-ranging applications including:

  • Ultra-fine particulate filtration
  • Pre-filtration before activated carbon filters, ion exchangers or reverse osmosis units
  • Shallow media layers, i.e. layers 200 - 400 mm in height
  • Dual media filters, used in combination with EVERZIT® N
  • Multi-media filters, used in combination with EVERZIT® N and quartz sand.

For optimum operation, we recommend use of a support layer of EVERZIT GS® in the grain size range 1.4 – 2.5 mm.
