Calibrated sand/ Filter sand

Filcom sand is ideally suited for water treatment by careful sieving and a low uniformity coefficient.

Filcom calibrated sand can be used in various ways.

  • Filter sand and filter gravel (drinking water, wastewater, process water, sewage water, swimming pool water and aquariums)
  • Fine-grained sand (water softening)
  • Infill sand (sports fields)

 

Filcom is the only company in the Netherlands that is certified by Kiwa to provide sand and gravel for the production of drinking water.
