Drinking water utilities are responsible for providing safe drinking water. As water directly impacts public health, water utilities follow stringent water treatment standards and processes. However to keep pace with the dynamic environment and tackle challenges such as water stress, water pollution, …

Information about the sources of plastic litter found in the Zeeuwse Delta is still scarce. This problem is addressed by this study with the aim to identify the possible sources of plastics that washed ashore on a selection of beaches in the Zeeuwse Delta. For this study the source and origin of the …

This research examines the water quality of Lake Volkerak-Zoom, focusing on annual returning blue-green algae (Microcystis) blooms. In addition, this research is focused on the possibility to sustainably remove 50% blue-green algae (Microcystis) from Lake Volkerak-Zoom using nutrient related measures, …

Since the Industrial Revolution, human activity has reinforced climate change to alarming rates and has introduced new stressors such as plastic pollution to the environment. Currently, 4.8 - 12.7 million tons of plastic litters enter the oceans every year. Globally alternatives to replace synthetic-based …

Waterschap Scheldestromen is curious about a 4-electrode conductivity sensor from Interuniversity Microelectronics Centre(imec), which provides a larger working range than Waterschap’s commercial 2-electrode sensor. The project aims to test the performance of this imec sensor, and couple it with Arduino …

The rapid implementation of large scale floating solar panels has consequences to water quality and local ecosystems. Environmental impacts depend on the dimensions, design and proportions of the system in relation to the size of the surface water, as well as the characteristics of the water system (currents, …

In this study, we present the e ects of time and temperature on the formation of urea deposits and their composition under conditions realistic to mobile heavy-duty SCR applications. To this end, various synthesis times were evaluated (1 h, 4 h and 24 h), as well as temperatures (298–673 K). The formed …

Small urban water bodies, like ponds or canals, are often assumed to cool their surroundings during hot periods, when water bodies remain cooler than air during daytime. However, during the night they may be warmer. Sufficient fetch is required for thermal effects to reach a height of 1–2 m, relevant …

This thesis project has been carried out at VHL (Van Hall Larenstein University of Applied Sciences) and consists of three different parts; the first part is an experiment in which during 20 days of cultivation the optimum nitrate concentration for protein production in Ulva lactuca is sought. U. lactuca …

Azorean waters have long been known to be inhabited by a vast number of cetacean species, representing a hotspot for marine wildlife within the North Atlantic. Various ecological factors are related to the complex habitat requirements of marine species such as water temperature, physiography and presence …
