Aus einem gezüchteten marinen Schwamm entwickelten Forschende der TU Bergakademie Freiberg einen innovativen Werkstoff. Reagieren die Fasern des Schwamms mit einer kupferhaltigen Ammoniaklösung, w ...
Based on his measurements hydrologist is able to calculate how the ground water quality will deteriorate in the future. what does he make of the government's approach. and i'm stuck on sort of recognizing the problem early on and working with us on solutions from i think they said there was no nitrate problem i knew a few of them still claim that one off yes the e.u. was threatening to impose fines time is running short on action has to be taken to . we accompany him to the land where he will inspect his latest sample too much nitrate in drinking water is carcinogenic with young children parti...
Isn't sufficient that's why in an additional treatment step the bavarian team is also testing two different filter systems the first employed sound in bacteria. the second uses activated carbon granules in early trials it was much more effective that's because the compounds left over after the nation it here readily to their uneven surface but the system has a drawback after two years at the latest the activated carbon particles are covered completely they can't absorb anymore so the filters have to be swapped out and cleaned which is complicated and expensive. that's why the researchers have ...
Is that the process of degradation could create problematic transformation products . so those own alone isn't sufficient that's why in an additional treatment step could be very intimidating also testing two different filter systems the first employed sounding bacteria. the second uses activated carbon granules in early trials it was much more effective that's because the compounds left over after as a nation and here are readily to their uneven surface but this system has a drawback after two years at the latest the activated carbon particles are covered completely they can't absorb any more...
A rifle noise his colleagues at the regional environment office they conduct tests for example in a comparison untreated samples turn reddish orange samples treated with ozone remain clear. but an overall exhibit when it comes to hormones we're very satisfied after ozone nation there are practically undetectible but with other medications the situation isn't quite as well. we have some good rates of degradation over ninety percent for example with back with a knock on average we're at about eighty five percent but that's not quite good enough since some of these medications like blood pressure...
