Passion for Quality and Efficiency in Biological Wastewater Treatment – For More Than 25 Years!

We manufacture MAGNUM® and STANDARD fine bubble tube diffusers as well as FLEXNORM® (EPDM) and FLEXSIL® (silicone) membranes in our own production facility with Made in Germany quality. We also develop and install turn-key aeration systems for high-performance municipal and industrial wastewater processing. Our HE® programme offers customers wide-ranging options for significant energy savings and/or increased throughput capacity.
