Will global warming force a shift in Biel’s drinking water intake? What caused the sudden turbidity of the water supply in the winter of 2009? Eawag has come up with answers to these and other questions for Energy Service Biel, and in the process, new questions have also emerged. Read more

Bastian Etter checks the quality of the stabilised urine, from which fertilizer will be made.
August 25, 2017

Eawag researchers working on the research project “VUNA” have developed a new recycling process with which nutrients in urine can be harvested and used as fertilizer. In order to further their ideology of sustainable handling of water and wastewater and to work out and implement innovative concepts of water and wastewater treatment, the researchers have founded the Spin-off Vuna GmbH.  Read more

Arsenic-contaminated groundwater used as drinking water or for irrigation may threaten the health of 50 to 60 million people in Pakistan. This is shown by an Eawag-led study – co-financed by SDC – in which data from 1200 groundwater samples was analysed and combined with geological and hydrological parameters to generate a hazard map.

Analyses of environmental gases which previously required months of laboratory work can now be carried out rapidly in the field. A group of Eawag scientists have developed a portable mass spectrometer allowing on-site measurements – and a spin-off has been created to commercialize the new system. Read more

April 27, 2017

If drinking water or wastewater containing bromide is treated with ozone to remove micropollutants, bromate – a potentially carcinogenic substance – is formed. Eawag scientists have developed a new process which makes it possible to minimize bromate formation during ozonation. This is achieved by transferring ozone to the water in small doses through the pores of PTFE membranes.  Read more

On 31 March 2017, «Gravit’eau» – a project run jointly by Eawag and the FHNW School of Life Sciences – was awarded the main 2017 prize in front of around 500 guests in Theater Basel. Read more

Urban water management 4.0 on World Water Day
March 22, 2017

The future of urban water management is also our future – this was the opinion of seven PhD students from Eawag came to, who decided to write a paper on the subject.  Read more
