Based on strictly selected raw materials and through an industrial process of washing, drying and sieving, we offer a significant range of closely graded filter sand and gravel. Specific sand fractions play an important role in the purification of water to create drinking water, for instance as fine-grained sand for water softening. Treating wastewater, sewage water, process water and recreational water has also helped us to find specific applications for our sands such as water extraction and soil energy, wellpointing, groundwater sampling and the removal of iron from water.
Choosing the right size as well as the right high-quality filter media is critical for an optimally functioning filter system. Thanks to our monitored production processes, our products always comply with your specifications, especially when it comes to the properties and composition of the material, the size of the grain or the toxicological and micrological aspects in the area of environment and health.
We can provide product certificate sand and gravel for the production of drinking water, certified by the Dutch test and research institute KIWA, including ATA (attest on toxicological aspects). Filter sand complies with European standard EN 12904 (materials for treatment of water intended for human consumption - sand and gravel).
We have an extensive established network and supply our products worldwide.
