Working Group for Urban Water Management / Water Supply

Welcome to the Water Supply Research Group at Hochschule Magdeburg-Stendal. Our group focuses on the research and development of innovative technologies and concepts for sustainable and efficient water supply. Our research areas include ozonation, advanced oxidation processes (AOP) followed by biofiltration, and the modeling of these processes. Our goal is to develop solutions that address the challenges of water supply in the 21st century while contributing to the protection and sustainable use of our water resources.

Completed Projects

Optimization of filter backwashing at the Oranienbaum water treatment plant

The goal of the project was to develop a concept for optimizing filter backwashing at the Oranienbaum water treatment plant when using expendable filter materials. The concept was created based on an extensive investigation program assessing the current state of filter operation and backwashing regimes.

Assessment of the treatment Process at the Oranienbaum Water Treatment Plant

The project aimed to conduct a comprehensive assessment of the groundwater treatment at the Oranienbaum water treatment plant, based on standard water quality parameters. The results of this assessment led to the identification of the optimization potential for the Oranienbaum water treatment plant.
