Get to know TZW in 186 seconds.

TZW’s comprehensive research activities and practical experience form the basis of solutions and concepts for all areas of national and international water management issues. These range from resource protection to water catchment and treatment to the water supplying consumers' taps. About 200 highly qualified staff members cooperate closely with water utilities, companies, expert authorities, and universities. TZW supplies reliable figures, data and facts, and creates solutions for a sustainable water supply. Part of DVGW - German Technical and Scientific Association for Gas and Water, TZW is a non-profit and independent institution.

What does the TZW test centre do?

A three-minute video shows what is done there to protect drinking water quality. Every material that comes into contact with drinking water must be thoroughly tested in Germany. Migration and microbiological testing, odour testing, mechanical testing and UV testing are just some of the many tests on the work schedule at the old waterworks in Karlsruhe. The video offers exciting insights behind the scenes of the TZW test centre.

The video offers insights into the work of the microbiologists at TZW.

It focuses on a research project entitled “Enterococci in drinking water systems”. In the DVGW-funded project, scientists at TZW used a new method to identify enterococci quicker using the MALDI-TOF spectrometer in order to identify possible contamination causes.

A BMBF research project uses artificial and collective intelligence to improve water quality.

The video offers interesting insights at the interface between water analysis and data science. The "K²I Trace Substance Tracker" is a cross-laboratory cloud solution that enables water suppliers to analyse detected organic trace substances more quickly using non-target analytics. A specialised drinking water laboratory, one of the leading data centres and a waterworks are the highly interesting locations in the video.

How does the pilot plant operated by TZW at the waterworks work?

Lukas Lesmeister from TZW takes you on a tour of the Rastatt-Rauental waterworks and explains the pilot plant for the removal of PFAS. The process that the scientists are currently developing as part of the EU ZeroPM project is a hybrid approach in which granular activated carbon and a regenerative ion exchange resin are combined to treat both hydrophobic and hydrophilic PFAS. The key to the sustainability and cost-effectiveness of this process lies in the fact that the service life of the granular activated carbon is extended. In addition, the ion exchange resin should be regenerated in such a way that as little sorption material as possible is used.
