New technologies and products

As a result of changed framework conditions, new regulatory requirements and social mega trends, there is a constant stream of new technologies and products on the market to treat, disinfect and post-process drinking water at the point of entry. These will be investigated as part of research work related to the efficiency, security and robustness for practical application. Technologies, products and materials already established or introduced in other industries play a major role. A high technology readiness level (TRL) is also extremely important. Past examples are membrane technology or in future, UV-LED technology and hybrid processes. Functionalised materials will also gain significance in future.

Drinking water treatment

Future developments in drinking water treatment concern the use of energy-efficient technologies that conserve resources. Existing processes are not only optimised in terms of their performance but also with regard to their energy, material and personnel efficiency. Membrane and hybrid processes are becoming increasingly competitive compared with conventional methods. The recycling of water company residues will gain importance. Structural and supply concepts must be adjusted to changing framework conditions (climate change, demographic development, industrialisation).

New systems and materials

Entirely new products that take account of the social mega trend of individualisation are expected in drinking water post-processing. Devices and systems to safeguard drinking water in the event of contaminations such as Legionella will also become more important. Research projects also investigate materials for their long-term behaviour, functionality and suitability.

UV and UV LED technology

Rapid development can be observed in the field of UV technology. This lies in the fact that UV emitters are being continuously optimised for energy reasons, and perspectively replaced by mercury-free radiation sources. A technological change will happen with UV LEDs, which requires entirely new reactor and monitoring concepts. At TZW, we are conducting various national and international research projects on this topic.
