Science that matters

The ETH Board has appointed Serina Robinson as Assistant Professor of Environmental Biochemistry. The scientist heads a research group in the Environmental Microbiology Department at Eawag.

An Eawag study at 10 WWTPs that use sludge densification shows that the process could improve capacity as well as nitrogen removal. 

Estimates as to how much more electricity could be generated from hydropower in the absence of residual flow requirements vary widely, and they have previously been based on inadequate data. A team of researchers from WSL, the University of Bern and Eawag has now used a new database and simulations to show that, between now and 2050, the additional decrease in production due to residual flow requirements – amounting to barely 2% – is likely to be much lower than feared.

The Swiss Federal Institute of Aquatic Science and Technology (Eawag) has been newly commissioned by the Federal Office of Public Health as the National Reference Centre for Wastewater Monitoring. This work centres around the collection of health data from municipal wastewater, and particularly that of viruses that are known to be pathogenic. A new national mandate has also been introduced for the analysis of substances related to pharmaceutical and illicit drug use.
