...crystal clear water
SiLi is a fifth generation family enterprise. Our company philosophy is based on tradition, innovation and sustainability, and we strive for stable, long-term cooperation with our customers, employees and business partners. We have produced and developed high-quality glass beads for over 150 years and grinding beads of zirconium oxide and zirconium silicate for over 10 years.
Our quality management, based on DIN ISO 9001, proved itself years ago; we also carry out work and tests with DIN ISO 15378 for pharmaceutics.
Press release:
Our extensive and well-grounded experience with the efficient use of natural resources has played an increasing role in our actions and decisions. Procuring water will represent a major challenge in the future, along with procuring alternative energy sources.
We want to remain active in this field with our products and ideas. We have made a detailed examination of the use of glass beads as support and filter material in cooperation with an established well sinker, other specialists in this field, and universities. After two years of research, the results confirm that our SiLibeads, beads of soda-lime glass, have the characteristics most suitable for this application.
The following advantages were discovered compared to standard filter gravel:
SiLibeads glass beads have almost the ideal shape for a sphere with a smooth surface, which clearly minimises the build-up of incrustation and reduces the regeneration frequency of the well.
SiLibeads Due to their homogeneity, SiLibeads possess a very high breaking strength, which is higher than that of filter gravel by a factor of 10. When the well’s annular space is filled, no breaks, undersized particles, or colmation particles form.
SiLibeads have a very narrow grain size distribution and are available in all size distributions. This way, the bead size can be selected to match the ground conditions. This also helps avoid colmation and reduces incrustation, thus lowering the regeneration costs. In addition, filling the well space with SiLibeads can prevent the development of harmful bridging formations.
SiLibeads soda-lime glass beads are free of impurities and heavy metals and do not display any concentrations of toxicological elements when used with acid-based regeneration substances.
