Fu, Mingyan (author)Organic micropollutants (OMPs) that occur in the aquatic environment at trace levels are emerging concerns to society. Domestic wastewater is an important source. OMPs end up in surface water and groundwater via conventional municipal wastewater treatment plants (WWTPs), penetrating drinking water. Comprising pharmaceuticals, personal care...doctoral thesis 2023

Calderon Franco, D. (author)Antibiotic resistance is one of the biggest threats to global health, food security, and development today, leading to a growing number of difficult-to-treat infections and an economic burden. It can affect anyone of any age and in any country. It is mainly accelerated by the misuse and abuse of antibiotics, poor hygiene, and a lack of...doctoral thesis 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

de Graaff, D.R. (author)Increase in sea level will lead to an increase in salinity in domestic wastewater systems. In order to anticipate its effects on biological wastewater treatment, the impact has to be assessed with lab-scale experiments. Aerobic granular sludge (AGS) is a successful technology for simultaneous removal of organic carbon (COD), nitrogen, and...doctoral thesis 2020

Suresh Kumar, P. (author)Eutrophication and the resulting formation of harmful algal blooms causes huge economic and environmental damages. Phosphorus (P) has been identified as a major limiting nutrient for eutrophication. Phosphorous concentration greater than 100 µg P/L is usually considered high enough for causing eutrophication. The strictest regulations however...doctoral thesis 2018

Zahmatkesh, M. (author)In order to address the ambiguities and knowledge gaps in the HA removal by WRF, mechanisms of removal were explored in chapter 2. It was shown that the mechanisms of HA removal by WRF involves the degradation of HA to smaller molecules, conversion to FA and also biosorption of HA by fungal mycelia. Furthermore, the ability of laccase to...doctoral thesis 2018

Hoekstra, M. (author)Currently wastewater treatment plants (WWTP) consume a lot of energy and surface area. While the incoming water contains chemical energy (BOD) and reusable resources which are not effectively utilized. The ideal is to develop a treatment scheme which allows for the efficient removal of pollutants while minimizing the energy input and maximizing...doctoral thesis 2017

Hu, J. (author)In the recent years, the removal of micro-pollutants from treated wastewater has been highly advocated throughout Europe and the rest of the world. The relevant regulations and the suitable techniques have been proposed accordingly, which promoted the innovation of the conventional wastewater treatment plants (WWTPs). Activated carbon adsorption...doctoral thesis 2016

Lotti, T. (author)Conventional wastewater treatment plants (WWTPs), like activated sludge systems, are energy demanding requiring a large electrical energy supply (e.g. 25 kWh PE-1 year-1) which, especially during peak-load periods, may account for an important quote of the grid installed power of the surrounding area. Only across the EU, there are 16000 WWTPs...doctoral thesis 2016

Welles, L. (author)Enhanced biological phosphorus removal (EBPR) is a biological process for efficient phosphate removal from wastewaters through intracellular storage of polyphosphate by polyphosphate-accumulating organisms (PAO) and subsequent removal of PAO from the system through wastage of sludge. In comparison to physical and chemical phosphorus removal...doctoral thesis 2015

Özgün, H. (author)In recent years, anaerobic membrane bioreactor (AnMBR) technology has been increasingly researched for municipal wastewater treatment as a means to produce nutrient-rich, solids free effluents with low levels of pathogens, while occupying a small footprint. An AnMBR can be used not only for on-site wastewater treatment, but also for the...doctoral thesis 2015

Dereli, R.K. (author)The success of anaerobic digestion relies on the presence of highly active methanogenic biomass, requiring effective retention of slow growing anaerobic microorganisms inside bioreactor by decoupling the hydraulic retention time (HRT) from solids residence time (SRT) or the employment of long SRTs in fully mixed systems. So far, flow through...doctoral thesis 2015

Erşahin, M.E. (author)Anaerobic membrane bioreactors (AnMBRs) physically ensure biomass retention by the application of a membrane filtration process. With growing application experiences from aerobic membrane bioreactors (MBRs), the combination of membrane and anaerobic processes has received much attention and become more attractive and feasible, due to advantages...doctoral thesis 2015

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

Mohd Amin, M.F. (author)The presence of micropollutants, especially pharmaceuticals, in wastewater has become a significant concern to both the water treatment industry as well as consumers. A new method of treatment was developed to curb this problem. The use of polymers as flocculants and combining them with materials helped to reduce the concentration of these...doctoral thesis 2015

Van den Brand, T.P.H. (author)The depletion of fresh water sources forces to design innovative integral solutions for the urban water cycle. Usual practice in most cities is to use drinking water to transport waste outside the city via sewer system. For toilet flushing the water quality is less important and seawater could be used as alternative to use of drinking water. Due...doctoral thesis 2014

Daelman, M.R.J. (author)Since 1750, the year that commonly marks the start of the Industrial Revolution, the atmospheric concentrations of carbon dioxide, methane and nitrous oxide have risen about 40 %, 150 % and 20 %, respectively, above the pre-industrial levels due to human activity (IPCC (2013) Climate Change 2013: The Physical Science Basis.
