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

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)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

(author), Kirichek, Alex (author), Habdank, Janis (author), Amman, Baerbel (author)Maintenance of the nautical depth in the seaport of Emden, Germany, is achieved by re-circulation of fluid mud using a trailing suction hopper dredger. Continued re-circulation has proven to maintain low settling rates and to keep yield stresses of re-circulated fluid mud below 50-100 Pa, in combination with densities of 1.15- 1.2 t/m³ enabling...conference paper 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
