Blankestijn, Rick (author)“Upwards along the pipes” focuses on the Tamansari subdistrict in Bandung, Indonesia, in which the Cikapundung river is a central physical element, dividing the highly dense informal settlements in two. The project tries to tackle several ecological and spatial issues occuring within the site, including a large amount of (organic) waste being...master thesis 2019

Gao, Chang (author)Certain industrial wastewaters have posed a big challenge to biological water treatment systems because of their high toxic organic compounds concentration (e.g. phenol) and high salinity. The maximum biomass specific phenol bioconversion rate (PhCR) of a mesophilic (35 °C) anaerobic membrane bioreactor (AnMBR) under high sodium concentration ...master thesis 2019

Visser, Thibaut (author)Besides wastewater and rainwater, the sewers in the Netherlands also transport a lot of water that is not supposed to be in the sewer. This water is called extraneous water and is the result of unwanted discharges in the sewer system. This could be groundwater infiltrating leaky sewer pipes, or pumped from construction sites directly into the...master thesis 2019

Ndayizeye, Christophe (author)‘Phytoremediation is the use of plants and their associated microbes for environmental clean-up’(Pilon-Smits, 2005). It is a natural, passive and efficient way of cleaning contaminated soil, water, and air. Every year, there are reports of contamination of swimmers due to the contaminated canal water round the Marineterrein in Amsterdam. The...master thesis 2019

Wang, Yundan (author)Nitrogen (N) removal is one of the key tasks for every wastewater treatment plant under the growing pressure of environmental protection. Prevailing applied N treatment technologies are mostly energy-intensive. This dilemma triggers a rethinking of the way to approach N management. “N2kWh-From pollutant to power” is a project that aims at...master thesis 2019

Bandinu, Giacomo (author)Municipal and industrial wastewater contains a significant amount of dissolved nitrogen. This is the results of the organic protein degradation and of the large employment of nitrogen (<i>N</i>), usually in the form of ammonia (<i>NH</i><sub>3</sub>), in the industry. Currently, nitrogen is removed in wastewater treatment plant (WWTP) by means...master thesis 2019

Rafiee, Poorya (author), Tong, Yen Wah (author), Hosseini, Maryam (author), Ebrahimi, S. (author)For further applications of microalgae such as bio-products, microalgal harvesting from its culture medium (e.g. wastewater) must be studied. This becomes more essential when investigating whether or not cells can stay viable to be recycled into the system. Microalgae culture, wastewater, and a mixture of both were separately...journal article 2019

(author), van Loosdrecht, Mark C.M. (author)The strong greenhouse gas nitrous oxide (N<sub>2</sub>O) can be emitted from wastewater treatment systems as a byproduct of ammonium oxidation and as the last intermediate in the stepwise reduction of nitrate to N<sub>2</sub> by denitrifying organisms. A potential strategy to reduce N<sub>2</sub>O emissions would be to enhance the activity of...journal article 2019

Saadabadi, S.A. (author), Thallam Thattai, A. (author), Fan, L. (author), Lindeboom, R.E.F. (author), Spanjers, H. (author), Aravind, P.V. (author)Anaerobic Digestion (AD) is used worldwide for treating organic waste and wastewater. Biogas produced can be converted using conventional energy conversion devices to provide energy efficient, integrated waste solutions. Typically, the electrical conversion-efficiency of these devices is 30–40% and is lowered due to biogas utilization instead...review 2019

Lam, K.L. (author), Zlatanovic, L. (author), van der Hoek, J.P. (author)Life cycle assessment (LCA) is an established methodology to assess the potential environmental impacts of products and processes. We reviewed 49 recent LCA studies (2010-2019) on wastewater nutrient recovery to synthesise some current methodological practices. Their scopes, variations, nutrient recovery accounting, uncertainty and sensitivity...conference paper 2019

van der Hoek, J.P. (author), Duijff, R. (author), Reinstra, Otto (author)Due to an increased food production the demand for nitrogen and phosphorus as fertilizers grows. Nitrogen based fertilizers are produced with the Haber-Bosch process through industrial fixation of N2 into ammonia. Through wastewater treatment the nitrogen is finally released back to the atmosphere as N2 gas. This nitrogen cycle is characterized...book chapter 2019

Amosov, M. V. (author), Zlatanovic, L. (author), Lam, K.L. (author), Solomonides, S. (author), van der Hoek, J.P. (author)The wastewater chain of Amsterdam offers an opportunity to recover up to 100% of phosphorus per year, versus 47% currently recovered. However, for the stakeholders of Amsterdam (e.g. citizens, business) it remains difficult to scale-up existing solutions for resource recovery. Mainly, due to the limitations of the widelyused methods (e.g. mass...conference paper 2019

Ampe, K.V.J. (author), Paredis, Erik (author), Asveld, L. (author), Osseweijer, P. (author), Block, Thomas (author)Recently, calls have increased for a paradigm shift or transition towards resource recovery and a circular economy in the Dutch wastewater system. However, we have observed diverging interpretations on the nature of the transition. This reflects the political environment of sustainability transitions: political struggle emerges over the...journal article 2019

(author)With the growth in production and use of chemicals and the fact that many end up in the aquatic environment, there is an increasing need for advanced water treatment technologies that can remove chemicals of emerging concern (CECs) from water. The current lack of a homogenous approach for testing advanced water treatment technologies hampers...review 2019

(author), Olsson, Gustaf (author), McMahon, James E. (author)The need for energy in water provision and use is obvious, however the drivers are often complex, difficult to assess, and often inconsistently presented. Here we build a clearer definition and conceptual framework of “water-related energy”. We apply this framework to harmonise data and results across disparate studies so that regional...journal article 2019
