Climate change accentuates heat waves in The Netherlands. This, in combination with high nutrient concentrations in Dutch surface waters, is intensifying the proliferation of toxic blue-green algae (cyanobacteria), a threat for the health of the population and ecosystems. Lakes are resources for recreational …

Summary Constructed wetlands have been used for decades on industrial areas to treat stormwater. European regulations and local ambitions for water quality dictate lower emissions before the water is discharged to the drainage system, surface water or infiltrated to ground water. The increase in the …

The combined impacts of urbanization and climate change pose significant threats for flooding and water quality in urban areas. Research shows that on average 83% of the flooding events were caused by gully pot blockages, stating the crucial importance of gully pot maintenance. Roadside gully pots are …

Floating wetland treatment systems (FWTS) are an innovative stormwater treatment technology currently being trialled on a larger scale in Australia. FWTS provide support for selected plant species to remove pollutants from stormwater discharged into a water body. The plant roots provide large surface …

An estimated 17 million tonnes of tires are discarded annually. Re-use is achieved by retreading (9%), recycling (39%), energy recovery (37%) and landfill (5%). A preferred, but complex way of recycling is to make new tires from discarded tire rubber. Vulcanised car tire rubber has to be devulcanized …

Stricter environmental policies, increased energy prices and depletion of resources are forcing industries to look for bio-based and low carbon footprint products. For industries, flax is interesting resource since it is light, strong, environmental friendly and renewable. From flax plant to fiber products …

Waterborne diseases are posing a constant threat for people. In developing countries there is a lack of microbiologically safe drinking water and in the developed countries there are occasional waterborne disease outbreaks. These diseases are caused by bacteria or parasites which can be found in various …

De waterkwaliteit van het oppervlaktewater in het beheergebied van Waterschap Peel en Maasvallei wordt sterk beïnvloed door de huidige landbouw, nalevering uit de bodem en water dat over de landsgrenzen binnenkomt. De verwachting is dat de nalevering uit de bodem nog tientallen jaren de waterkwaliteit …

The Pierre Auger group is studying ultra-high energy cosmic rays. Cosmic rays are charged particles which permanently hit and penetrate the atmosphere of the Earth. They will at a certain moment collide with nuclei in the atmosphere, like nitrogen. The results of such an interaction are new particles, …

Dit onderzoek richt zich op de twee RWZI’s van Uithuizermeeden en Uithuizen die in 2012 moeten worden samengevoegd tot één RWZI in Uithuizermeeden. In dit onderzoek is aandacht besteed aan de gevolgen van deze samenvoeging ten aanzien van de lozing van effluent op het Meedstermaar. De RWZI te Uithuizermeeden …
