SiLibeads certified according to NSF/ANSI/CAN 50
We did it!
We are the first glass beads manufacturer in the world to achieve NSF/ANSI/CAN 50 standard certification for our Type S glass beads. This standard was developed by experts from a group of manufacturers, health authorities and users and evaluates the suitability of equipment for swimming pools, spas, hot tubs and other recreational water facilities. This ensures that certified equipment meets the highest standards of performance, such as the health effects of materials, performance, labeling and user instructions. This is achieved through strict test specifications with rigidly defined criteria. For filter media, for example, filtration performance with contaminated water (45 NTU ± 5 NTU), cleaning during backwashing after filtration with contaminated test water, and pressure drop with clean (± 2 NTU) and contaminated water (45 NTU ± 5 NTU) are tested here. In addition to application-related parameters, general material properties such as grain distribution, non-uniformity (Cu) and roundness are also evaluated.
Both our SiLibeads Type S 0.40 – 1.20 mm and SiLibeads Type S 0.50 – 1.00 mm successfully meet the requirements, which is expressed by the receipt of the certificates and the listing on the NSF website. This proves the best suitability of our SiLibeads Type S glass beads as filter media for swimming pools, spas, whirlpools and similar applications.
