MICRODYN-NADIR has a worldwide reputation for its innovative membrane products for microfiltration, ultrafiltration and nanofiltration. A global player today, the company maintains strong links with its origins. Its headquarters are located at the Kalle-Albert Industrial Park in Wiesbaden, Germany, where the MICRODYN-NADIR story began more than 50 years ago. MICRODYN-NADIR is the technology leading membrane and module supplier for the micro-, ultra- and nano filtration worldwide. The membrane division of the former Hoechst AG which used to be known as NADIR Filtration was founded in 1966. In 2003, NADIR Filtration and MICRODYN Modulbau, whose roots go back to the AKZO AG, merged and have been an important player in the membrane market as MICRODYN-NADIR ever since.
