Report from the ATW 2023


This year, the 15th Aachen Water Technology Conference returned in presence and was again held at the Eurogress Aachen. As in previous years, we were able to attract renowned scientists and authority speakers.

On the first day of the conference, Prof. Erik Roesink (NX Filtration, Netherlands) started with insights into the production and applications of hollow fiber nanofiltration membranes. Subsequently, Regina Gnirss (Berliner Wasserbetriebe, Germany) and Dr. Marie Launay (Kompetenzzentrum Spurenstoffe Spurenstoffe Baden-Württemberg, Germany) gave interesting insights into the potentials of membrane processes and trace substance recovery in urban wastewater treatment plants. On the second day, Prof. Jörg Drewes (Chair of Urban Water Management TU Munich, Germany) gave a presentation on perspectives and technologies of alternative water resources. Finally, Prof. Andrea Iris Schäfer (Institute for Advanced Membrane Technology Karlsruhe Institute of Technology, Germany) presented the development of off-grid water treatment systems for use in developing countries.

At the meeting, the 56 speakers presented their latest technological developments and operational experiences on large-scale systems in a total of 12 sessions. The membrane, adsorption and oxidation processes discussed, as well as their combinations, represent the most important approaches to the current challenges of water treatment and wastewater purification: Industrial and municipal recycling management, resource recovery and sustainable resource use, and elimination of trace substances.

A trade exhibition featuring 26 leading companies from the water sector framed the conference and provided a platform for stimulating discussions. With more than 400 participants, the Aachen conference represents the largest German-speaking, process engineering conference in the water sector.

As in previous years, the 15th Aachen Conference on Water Technology was jointly organized by the Department of Chemical Process Engineering at Aachen Process Engineering (Prof. Wessling) and the Institute of Urban Water Management (Prof. Wintgens) at RWTH Aachen University.

We are already looking forward to the 16th Aachen Water Technology Conference on November 11 and 12, 2025 in Aachen.
