The current Aqua&Gas issue 3/2023 focuses on the WWTP Brienz, which was newly built and equipped with the ARAbella control system from STEBATEC. Read the report to find out why the wastewater treatment manager Michael Baumann particularly appreciates the menu-guided and reliable flexibility for optimising his processes.
After a planning phase lasting several years, which resulted in an approved water rights notice, the next step is to equip the neuralgic points in the 370 km long sewer network of the wastewater association in Upper Austria with the measuring and control technology shown in the picture.
The increasing digitalisation of sewer networks and the possibility to dynamically regulate and optimise them open up new and unexpected potentials. We offer economic solutions that make it possible to prevent overflows in the future.
Stebatec offers the algorithm-based INKA system and regularly publishes measurement data that provide information about the functionality of the system. In order to establish a certain degree of comparability with other systems, the company has now developed some evaluation options that enable both unregulated with dynamic, but also the comparison of different dynamic systems.
In December 1990, Hanspeter Gafner founded STEBATEC together with two business partners, thus laying the foundation stone of a long success story. With some articles under the title «30 YEARS STEBATEC», we will share our history with you here in the coming weeks.
The Zweckverband der Abwasserregion Olten (ZAO) is an association of 13 municipalities which treat their wastewater in the WWTP Winznau. The WWTP itself was and is already the subject of refurbisching measures, but other structures in the sewer network also showed a considerable need for refurbischment, including pumping stations and storm water tanks.
Intelligent management of the storage volumes in the sewer network makes a major contribution to water protection, reduces overflows, makes optimum use of the storage volume in the sewer network and ensures the hydraulic capacity utilisation of the sewage treatment plant.
