Water is the world’s most precious resource. But although nearly 70 per cent of the world’s surface is covered with water, only about 0.007 per cent of the earth’s water reserves are available to us directly.

Pharmaceuticals in particular play a role here that cannot be overlooked. Their active agents and degradation products are excreted by humans and animals, thereby finding their way into the hydrological cycle via sewage. This waste is compounded by out-of-date medicines that are flushed down the toilet.

Sewage treatment plants are not designed to remove these substances at present, or have long reached the limit of their performance. That means new concepts are required which also purify the water of these substances and hence improve water quality crucially. Water 3.0 – the first efficient process for removing pharmaceutical residues from water – with sustainability and environmental friendliness as targets.

Since 2012, Jun.-Prof. Dr. Katrin Schuhen has been actively engaged in research together with her working group at the Institute for Environmental Sciences at the University of Koblenz-Landau. Her research centres on the development of innovative materials that fully remove residues from wastewater (sewage) and drinking water. The focus here is on hybrid silica gels, which are ideal reaction partners for diverse substances with their organic and inorganic units.



In Project 3.0, Jun.-Prof. Dr. Katrin Schuhen is researching new materials for the removal of anthropogenic stressors from water along with her team at the University of Koblenz-Landau.

Research only works if you have the right development partners onboard. Cooperation with Zahnen Technik is an important means of spurring on the materials science research results and implementing them in process technology.

Thanks to the Zahnen Engineering Tools, the research team is able to respond in line with the requirements associated with the customer’s situation. That is an essential factor for Water 3.0, as it enables new options to be devised in order to make the research more adaptable to various stressor loads.

With Water 3.0 and the cooperation partner Zahnen, a mobile container solution is to be available in the near future, enabling variable contaminants to be tackled so that access to clean water can be ensured everywhere in the world.
