In terms of methods we conduct our services either by the more classical absorption measurements or by clean and easy desorption measurements as well as measurements according to the offgas method. Our services usually aim at the verification of guaranteed performance values but are also valuable as a general performance assessment of existing systems.

The proof of guaranteed performance values is a frequently requested service following the renewal of the aeration system. It is preferably performed as pure water measurement and is often time critical. Automated data recording allows us to continuously monitor the quality of our measurements, this helps us to minimize the delay between measurement and final report.

With our general performance assessment of the aeration system we support operators in monitoring the aeration efficiency of their plants. Regular, e.g. bi-annual determination of the oxygen transfer rate generates knowledge about the degradation of the aeration system over time and thus helps to estimate the economically most feasible moment for renewal. These measurements are conducted in activated sludge. Tests are possible even under full operation conditions (i.e. without operational interruption) when the offgas method is applied.

Our range of methods for aeration efficiency testing is completed by the possibility of on-site determination of the alpha factor, flow measurements and air flow measurements. We provide our services in Germany and, if required, worldwide.

We see ourselves in the tradition of the long-standing work of Dipl.-Ing. Gero Fröse, who together with Prof. Kayser established these measurements at the Braunschweig University of Technology in the 1980s and continuously developed them further until the beginning of the 2020s. Today he is still on our side as a mentor. Together we completely renewed all technical equipment with a special focus on mobile deployment.
