Silica sands are used as filter media for drinking water treatment and wastewater treatment. Our ultra-pure filter sands and gravels are characterised by their particularly high quartz content and naturally comply with the requirements specified in DIN EN 12904 and DIN EN 15798. This provides official confirmation for their use in treating drinking water as well as for use as filters for swimming and bathing water. Our silica sand is guaranteed to be free of fine particles and reliably ensures the cleanest possible water filtration.

Our products comply with DIN 4924 filter sands and gravels for well construction. Our filter sands and gravels have a rounded grain shape and are free of organic impurities.
