Fighting Chemical Pollution Water: Purification using Algae

Fossil remains of diatoms can efficiently remove contaminants from water after being chemically modified

28-Jan-2025 - Europe's water bodies are in poor condition: more than half of them are heavily polluted with chemicals. This is hardly surprising – every day, up to 70,000 different chemicals are used in Europe’s industries and agriculture. Researchers at the University of Duisburg-Essen have now developed a ...

Researchers develop a new material that removes a dangerous “forever chemical,” from drinking water

Powerful technology can detect and filter out chemical linked to cancer and other health risks, potentially revolutionizing water purification efforts

09-Dec-2024 - Researchers at NYU Abu Dhabi (NYUAD) have developed an innovative cationic covalent organic framework (COF) that efficiently detects and removes perfluorooctanoic acid(PFOA), a harmful and persistent pollutant, from drinking water. This breakthrough addresses a global challenge of removing ...

Nanofibers rid water of hazardous dyes

Waste to purify water - it sounds paradoxical, but that is exactly what has now been achieved

25-Apr-2024 - Dyes, such as those used in the textile industry, are a major environmental problem. At TU Wien, efficient filters have now been developed – based on cellulose waste. Using waste to purify water may sound counterintuitive. But at TU Wien, this is exactly what has now been achieved: a special ...

Clean water from fog

A property known as photocatalytic memory ensures that this also functions when skies are overcast and at night

25-Aug-2023 - Researchers at the Max Planck Institute for Polymer Research and ETH Zurich are using a specially coated metal mesh to extract water from fog while removing environmental pollutants. People in dry but foggy areas could benefit. It's already being done in Peru, Bolivia and Chile, but also in ...

Cleaning water with ‘smart rust’ and magnets

New method for pollutants such as crude oil, glyphosate, microplastics and hormones

22-Aug-2023 - Pouring flecks of rust into water usually makes it dirtier. But researchers of FAU have developed special iron oxide nanoparticles they call “smart rust” that actually makes it cleaner. Smart rust can attract many substances, including oil, nano- and microplastics, as well as the herbicide ...

PFAS contaminated water becomes clean again

Promising and environmentally friendly process developed

25-Jul-2023 - There are many man-made environmental pollutants. One of the most serious is pollution with the harmful perpetual chemical PFAS, which can be found in many soils and waters and thus also in our food. Although it is possible to remove it, it is costly and produces hazardous waste. Now, researchers ...

Magnetic bacteria can help to extract dangerous heavy metals from wastewater

Filigree sewage plants

10-May-2023 - A research team at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has managed to purify water containing uranium using a special kind of bacteria known as magnetotactic bacteria. The name derives from their ability to react to magnetic fields. They can accumulate dissolved heavy metal in their ...

Plasma against toxic PFAS chemicals

“Ideally, the harmful PFAS substances are eliminated to the point that they can no longer be detected in mass spectrometric measurements”

04-May-2023 - Harmful PFAS chemicals can now be detected in many soils and bodies of water. Removing them using conventional filter techniques is costly and almost infeasible. Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB are now successfully implementing a ...
