Utmost reliability for our customers is ensured by our DIN EN ISO 9001 - certified quality management system for the storage and trade of products for water treatment. Comprehensive in-house quality control of EVERZIT® N manufacturing ensures consistently high quality.

Grain size distribution is realized by a proprietary process with unparalleled precision to fulfil specific application requirements (oversize and undersize fractions < 5 %). We comply fully with DIN, EN, AWWA and other commonly used standards. Our internal quality specifications are however considerably stricter than these regulations in many instances.
