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

Tinti, Francesco (author), Kasmaeeyazdi, Sara (author), Guatame-Garcia, Adriana (author), Chagnes, Alexandre (author), Chernoburova, Olga (author)This chapter addresses the general properties and characteristics of the following residue categories: mining wastes, mineral processing wastes or tailings, metallurgical wastes (slags, dusts, slimes, and muds), and wastewaters. Residue origin, storage, disposal, and a brief indication of associated environmental impacts are discussed;...book chapter 2023

Pothof, I.W.M. (author), Clemens, F.H.L.R. (author)Air-water flow is an undesired condition in water pipelines and hydropower tunnels. Water pipelines and wastewater pressure mains in particular are subject to air pocket accumulation in downward sloping reaches, such as inverted siphons or terrain slopes. Air pockets cause energy losses and an associated capacity reduction. Despite its practical...conference paper 2012

Van der Helm, A.W.C. (author), Bhai, A. (author), Coloni, F. (author), Koning, W.J.G. (author), De Bakker, P.T. (author)Three years after Zaatari camp was established in the Hashemite Kingdom of Jordan, to host Syrian refugees, its population has grown to 82,000 persons. Zaatari is one of the largest refugee camps in the world, in one of the most water scarce areas on earth. Since its establishment, drinking water has been delivered by trucks to communal...conference paper 2015

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

Clemens, F.H.L.R. (author), Duinmeijer, S.P.A. (author)Sumps of wastewater pumping station can experience problems due the formation of (solid) floating layers of fat and scum as a result of insufficient current guidelines for sump design with respect to transport of floating debris. To complimentary the guidelines, the use of free-surface vortices is defined as a potential transport mechanism for...conference paper 2016

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

Amosov, M. V. (author), Zlatanovic, L. (author), van der Hoek, J.P. (author)The wastewater system of Amsterdam offers an opportunity to recover phosphorus, and contribute to circular economy. However, it remains unclear where to intervene in system to maximize recovery and valorisation in a resilient and feasible way. The Design Structure Matrix method was tested to define the system architecture from Food-Water-Energy...conference paper 2018

Langeveld, J.G. (author)Wastewater systems consist of sewer systems and wastewater treatment works. As the performance of a wastewater treatment plant is affected by the characteristics, i.e. operation and design, of the contributing sewer systems, knowledge of the interactions between sewers and wastewater treatment works is very important when trying to understand...doctoral thesis 2004

Schilperoort, R.P.S. (author)The wastewater system in the Netherlands comprises approximately 100,000 km of sewer pipes and more than 350 wastewater treatment plants (wwtp). The system collects and treats the majority of domestic and industrial wastewater. A small amount of untreated wastewater, however, is occasionally discharged to rivers and lakes, often resulting in a...doctoral thesis 2011

Elias Maxil, J.A. (author)This text presents an approach to assess the energy content (flow and temperature) at any point of the sewer system based on the coupling of a stochastic model to predict drinking water demand from households and a model to estimate the temperature distribution in the sewer network. An application example is given where the developed tool is...doctoral thesis 2015

Valladares Linares, R. (author)Since more than 97% of the water in the world is seawater, desalination technologies have the potential to solve the fresh water crisis. The most used desalination technology nowadays is seawater reverse osmosis (SWRO), where a membrane is used as a physical barrier to separate the salts from the water, using high hydraulic pressure as the...doctoral thesis 2014
