On March 31th, Dr. Thu-Ha Nguyen successfully defended her thesis on wave-overtopping processes for very mild sloping and shallow foreshores, supervised by Marcel Stive and Bas Hofland. For Marcel, this was a special occasion, as Thu-Ha was his last PhD in his role of promotor here at TU Delft. Starting back in 2003 with a tall Dutchman who obtained his degree with a thesis on Argus video imaging, Marcel has acted as the promotor of no fewer than 51 PhD candidates, 46 at TU Delft and 5 at other academic institutes.

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

Paco Lopez Dekker: Harmony in the Wadden

An important milestone in the preparation of ESA’s tenth Earth Explorer candidate satellite mission, Harmony, has been reached thanks to two aircraft flying in tight formation over the Dutch Wadden Islands collecting key data on sea state and currents. The main purpose of this tricky airborne experiment is to mimic the geometry at which the Harmony satellites will measure various aspects of ocean dynamics to understand how air and the ocean surface interact, which, in turn, will improve weather prediction and climate models.

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.

CEG participates in setting up the first Lithium production line in Europe
Lithium is a scarce resource that is essential for the production of batteries. Yet batteries we urgently need to enable the energy transition, as they provide efficient ways to store wind and solar energy. We therefore need ways to process lithium more efficiently, techniques to refine and ways to recycle. A consortium of European companies and universities, including TU Delft’s Resources & Recycling group, aims to set up the first-ever Lithium supply chain in Europe.
