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.

Project duration: June 2023 - February 2024
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.
