A planetary boundary for green water

A planetary boundary for green water

Water is the bloodstream of the biosphere, but we are profoundly changing the water cycle. This is now affecting the health of the entire planet, making it significantly less resilient to shocks. A reassessment of the planetary boundary for freshwater indicates that it has now been transgressed, according to a recent assessment. The paper was performed by an international consortium, led by by Stockholm Resilience Centre, and published on Nature, April 2022.

Two CEG researchers receive Veni grant

Two CEG researchers receive Veni grant

The Dutch Research Council (NWO) has awarded a Veni grant worth up to 280,000 euros to two highly promising young scientists of the Faculty of Civil Engineering & Geosciences. The grant provides them with the opportunity to further elaborate their own ideas during a period of three years. A total of nine Veni's have been awarded to TU Delft researchers.

Cooperation Witteveen+Bos – TU Delft

Cooperation Witteveen+Bos – TU Delft

At the end of this month, two years have passed since I started working at the African Water Corridor Initiative. It will be also 18 months since I have left behind my life in the Netherlands to start my new life in West Africa, in Ghana. My name is Jasper Schakel and in contrast like many other people working at the TU Delft, my employer is not the TU Delft, but the international engineering firm Witteveen+Bos. Two years ago I talked with Doris van Halem where she introduced me to the African Water Corridor

AdOx – from laboratory research to pilot plant research

AdOx – from laboratory research to pilot plant research

After almost four years of lab research, the AdOx process will be tested on pilot plant scale. AdOx is an innovative technology for removal of organic micropollutants (OMPs), such as pharmaceuticals, from domestic wastewater effluent. It combines adsorption with oxidation: zeolite granules remove OMPs from treated wastewater effluent by adsorption in a fixed bed filter, and the zeolite filter is regenerated with ozone gas after the zeolite granules are exhausted. The process is very selective for OMPs, cost-effective and extremely sustainable: the CO2-footprint is low, no bromate and oxidation by-products are released to the receiving surface water, and the ozone use is low. It is a very competitive technology compared to GAC filtration and direct ozonation of wastewater effluent.
