New Eawag spin-off advises wastewater treatment plant
TechTransfer
Eawag
Environmental engineer Wenzel Gruber and microbiologist Robert Niederdorfer – both Eawag postdocs – founded the spin-off Upwater together with two other partners at the beginning of November 2022. It offers measurements for wastewater treatment plants to support them in reducing process instabilities, greenhouse gas emissions as well as energy consumption.
Glacial melt threatens habitats of alpine river organisms
Research
Eawag
When glaciers retreat, the habitats for cold-water organisms also change. Researchers have now modelled where refuges that are vital for biodiversity in glacial rivers will remain in the future.
DNA traces in groundwater
Research
Eawag
An Eawag study shows that a large variety of living organisms leave their DNA traces in groundwater – which also depends on the land use in the catchment area. In future, these biological parameters could be used to assess groundwater quality.
Improving the microbial quality of recycled water in Bengaluru
Research
Eawag
In urban India, rising water scarcity and increasing pressure on water supply utilities have prompted the use of treated wastewater as an alternative source. A study of Eawag together with Indian partners explains how the use of sensors and automated chlorination can improve microbial water quality in on-site water reuse systems for increased user safety.
Tracing mine accidents with satellite data
Research
Eawag
Mining repeatedly causes water pollution. In the Global South, polluters often get away with it because the waters are seldom monitored. Satellite data can provide evidence of the origin, spread and extent of environmental disasters.
Fish diversity documented in Switzerland’s rivers
Research
Eawag
In a survey of Swiss rivers and streams, more than 50 different fish species were recorded. For the first time, more than one species was also found in the case of smaller types of fish such as the bullhead.
