Norwegian University of Science and Technology (NTNU)
Norwegian University of Science and Technology (NTNU) is a university that is part of the pulse of the water sector. Here we bring together everything it publishes on Smart Water Magazine: its news, its blogs and the events it takes part in.
Ultrasound can save fish in hydropower rivers
The phenomenon of gas supersaturation occurs when air enters water-filled hydropower inlets and is then exposed to high pressure. When this water is subsequently released into the river below the hydropower plant, it's almost like opening a bottle of champagne, filling the river with bubbles. There is so much air in the water that it […]
The ice in Antarctica has melted before, says study
Sixty percent of the world's freshwater is bound up in Antarctic ice sheets. Thirty million cubic kilometers of ice is perhaps a difficult number to grasp. But if absolutely all Antarctica's ice melted, the seas would rise by 58 meters on average. "The ice sheet in East Antarctica stores enormous amounts of water. This means that this is the […]
Norwegian rivers need to be better protected
When hydroelectric power plants suddenly switch off the water, we risk killing fish fry and other living organisms in rivers. The regulations need to change, say scientists and anglers.
Municipal wastewater treatment plants to recover fertilizers to aid farmers
Nutrients contained in wastewater, such as phosphorous and nitrogen, can be put to good use as fertilizers. Municipal wastewater treatment plants are now planning to recover more of these valuable resources, which are becoming globally scarce. "Wider Uptake" is a joint project involving water and sewage treatment companies, research institutes and private sector businesses in […]
Well-meaning climate measures can make matters worse
Lifestyle changes can reduce our greenhouse gas emissions and help protect nature. While some actions offer great potential, some aren’t as effective as we think and may even require more land and water, such as shifting to renewable energy. We need to change our lifestyle if we want to make a dent in greenhouse gas […]
Clean water eliminated effects of discharged drugs in fish
The discharge of pharmaceutical drugs is a major problem around the world, but a new study of the freshwater fish burbot shows that there is hope. The development of new drugs is a good thing for both humans and animals. But unfortunately, the medications we take can have untoward consequences. Discharges of medications by the […]
