Sibelco offers a full portfolio of high-performance filtration sands, gravels and other media. After careful selection and extraction, all sands are washed, dried and sieved within rigorous quality control parameters. This ensures high quality products that deliver maximum performance over a long period of time. Sibelco’s worldwide reputation for quality and reliability is just one of the reasons why leading water and wastewater treatment experts choose Sibelco sands.
Paques applies Sibelco’s sands for its ASTRASAND® continuous filtration systems at Leiden Noord wastewater treatment plant in the Netherlands. The plant, which treats approximately 26 million litres of wastewater per day, is harnessing the power of Paques’ ASTRASAND® systems to remove nitrogen and phosphorous, thereby further enhancing effluent quality in line with increasingly stringent environmental standards.
Sibelco’s sands are perfectly suited to continuous filtration systems like ASTRASAND®. Continuous filtration equipment demands accurately-processed filter sands. The specific shape of the sand facilitates the constant moving of the sands and hence the uninterrupted filtration and cleaning process. At the same time, the precise grading reduces the filter bed resistance.
