September 7, 2023Timely analyses of the bacterial community in wastewater treatment plants enables changes to be detected and remedied before cleaning performance suffers.
August 17, 2023The combined sewer system is a great achievement. But the discharge of diluted wastewater into central sewage treatment plants is approaching its limits.
July 14, 2023Barbara Jeanne “BJ” Ward received the ETH Medal for her doctoral thesis on predicting the dewatering capacity of faecal sludge in mid-July. The medal honours excellent master and doctoral theses at ETH Zurich each year.
May 16, 2023Container-based sanitation has the potential to generate carbon credits through avoided greenhouse gas emissions. Eawag, the Swiss Federal Institute of Aquatic Science and Technology, worked on developing a draft methodology to quantify these emission savings.
May 9, 2023Environmental 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.
May 8, 2023When 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.
April 28, 2023The hot summer made water supply security a political issue in 2022. Added to this were deficits in groundwater protection and "eternal" chemicals.
April 20, 2023In 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.
April 11, 2023Nitrous oxide is one of the main greenhouse gases and also contributes to the destruction of the ozone layer. One of the places where it is released is in wastewater treatment plants. A study has now investigated how much of this is due to the treatment of sludge liquid, which is to be expanded over the next few years.
March 17, 2023The UN Water Conference is an urgent appeal to the global community to act on Sustainable Development Goal 6 - Clean Water and Sanitation. Eawag is willing to make its contribution and presents new approaches such as the Urban Water Flow Diagram, which improves water management in cities.
