de Vries, Irene (author)Polders water canals are sometimes exposed to brackish seepage from the nearby saline sea (salinization). This is a problem because the canal water is used to irrigate crops. A characteristic of water is that less dense (fresh) water floats on top of dense (saline) water. In lakes and oceans, it is common that water layers with various densities...master thesis 2023

Maus, Sönke (author), Bahafid, Sara (author), Hendriks, M.A.N. (author), Jacobsen, Stefan (author), Geiker, Mette Rica (author)Frost salt scaling of concrete is related to cyclic freezing and melting of a few millimeter thick deicer solution on the surface of the concrete. It is almost absent when pure water is freezing and reaches a maximum at a so-called pessimum concentration that for NaCl is around 3%. Different mechanisms have been suggested to explain this...journal article 2023

Chen, Kuei-Tso (author)The city of Rotterdam has a long and interesting history. It began as a small settlement on the River Rotte, at the place where the river met with the Nieuwe Maas. In 1270, the long dam was built in an attempt to reclaim the swampy land for development. In another word, since its origins, Rotterdam had to adapt to the natural circumstances of...master thesis 2022

Muñoz Sierra, Julian (author)Industrial wastewaters generated in chemical industries are often characterized by extreme conditions, such as the presence of complex, recalcitrant, and toxic aromatic compounds, high temperature, and high salinity. The mentioned conditions predominantly occur when chemical industries reduce process water use or strive for closing water loops....doctoral thesis 2022

(author)Treating petrochemical wastewater is a challenge for conventional anaerobic reactors. One example is coal gasification wastewater that, besides its salinity, is rich in toxic and inhibitory aromatics, such as phenol, cresols, and resorcinol. Studies have shown that phenol and p-cresol share the same degradation intermediates, whereas...journal article 2022

van den Berg, L. (author), Pronk, M. (author), van Loosdrecht, Mark C.M. (author), de Kreuk, M.K. (author)Granular sludge processes are frequently used in domestic and industrial wastewater treatment. The granule buoyant density and biomass density are important parameters for the design and operation of granular sludge reactors. Different methods to measure the granule density include the pycnometer method, the Percoll density gradient method,...journal article 2022

(author)The Vietnamese Mekong Delta (VMD) is an example of a complex dynamic socio-hydrological system in which societies and hydrology interact and co-evolve. The dominant engineering approach in the VMD has enhanced the dynamics of society and hydrology. This study looks at the implications of socio-hydrological dynamics in the coastal VMD where...journal article 2022

Aydin, B.E. (author), Oude Essink, Gualbert H.P. (author), Delsman, Joost R. (author), van de Giesen, N.C. (author), Abraham, E. (author)A significant increase in surface water salinization in low-lying deltas is expected globally due to saline groundwater exfiltration driven by rising sea levels and decreasing freshwater availability. Sustaining fresh water-dependent agriculture in such areas will entail an increased demand for fresh water flushing. Unfortunately, the...journal article 2022

Mirzaie Yegane, M. (author), Boukany, P. (author), Zitha, P.L.J. (author)Due to increased energy demand, it is vital to enhance the recovery from existing oilfields. Polymer flooding is the most frequently used chemical enhanced oil recovery (cEOR) method in field applications that increases the oil sweep and displacement efficiencies. In recent years, there has been growing interest to assess the use of polymer...journal article 2022

Tedeschi, Anna (author), Cerrato, Domenico (author), Menenti, M. (author)There is a new and growing interest in using hemp as a raw material for a wide portfolio of food and non-food products. This study provides a synthesis of such information on the basis of literature and experimental data. For comparison, similar information on maize is provided. To document multiple uses of both crops, a list of products was...journal article 2022
