Why Sibelco filter materials?

Water treatment materials engineered to your specification, for consistent results every time

Your filtration system demands the best media. To deliver maximum performance, filtration sands need to meet precise specifications for factors such as particle size distribution, uniformity coefficient, loss on ignition, sphericity, hardness and silica content.

At Sibelco, we place the quality of your filtration media at the centre of our business. We use specialist processing equipment and the latest laboratory technology, employing rigorous quality control checks throughout and after production. Raw materials are carefully selected, washed, dried and sieved to guarantee a low uniformity coefficient.

Our plants are certified to MEN-EN-ISO 9001:2015 quality management standards, whilst our filter sands comply with EN 12904 standard. The Wessem, Netherlands site has silica fulfilling KIWA certification. The products from France are ACS-certified.

Higher quality for a longer lifespan and lower operating costs

Whilst a relatively low-cost element of a filter system’s total design, filtration media have a major impact on the system’s overall performance. The quality and consistency of our filter sands ensure a longer filter media lifetime and high performance, which means you spend less time and money replacing media. Our materials also enable long filter runs and efficient backwashing, which means lower maintenance costs. So in comparison to cheaper alternatives, our solutions ultimately provide a more cost-and higher value-in-use solution for your filter system.   

“Sibelco filter sands have been used at our drinking water treatment plant for a number of decades without decreasing performance” – Process technology expert, Brabant Water.
