30 years ago Arnold Jäger, proprietor of Gummi-Jäger during its 2nd generation, was approached by the German water utilities to develop his first aeration membrane from rubber. At that time, German water purification plants typically used aeration technologies relying on ceramic membranes. Yet rising energy and wage costs in the German communities compelled them to seek new technologies.

Inspired by the idea of saving energy and lowering operating costs, he developed an EPDM membrane together with his sons.

His extensive knowledge in chemistry and rubber processing, lean manufacturing and quality control helped Arnold Jäger find a unique solution for the German wastewater treatment industry.
