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...

Mooij, P.R. (author)
This thesis deals with selective environments in microalgal cultivation. As explained in Chapter 1 microalgae have changed the course of life on Earth dramatically by performing oxygenic photosynthesis. In oxygenic photosynthesis electrons from water are used to reduce carbon dioxide to carbohydrates or lipids using solar energy. As a waste...

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...

Anaerobic digestion is a widely applied process in which close interactions between different microbial groups result in the formation of renewable energy in the form of biogas. Nevertheless, the regulatory mechanisms of the electron transfer between acetogenic bacteria and methanogenic archaea in the final steps of the anaerobic digestion...

Challenges to achieve biological stability in drinking water distribution systems Drinking water is distributed from the treatment facility to consumers through extended man-made piping systems. The World Health Organization drinking water guidelines (2006) stated that “Water entering the distribution system must be microbiologically safe and...

Polyhydroxyalkanoate (PHA) is a natural product that can potentially replace a part of the chemicals and plastics derived from fossil sources. One of the main barriers for market entry of PHA is its relatively high price compared to conventional (fossil) feedstocks. This high price is related to current industrial production methods which are...

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...

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. Working Group I...

Van den Brink, P.F.H. (author)
The widespread application of membrane bioreactors (MBRs) for municipal wastewater treatment is hampered by membrane fouling. Fouling increases energy demand, reduces process performance and creates the need for more frequent (chemical) membrane cleaning or replacement. Membrane fouling in MBRs is known to be caused by several membrane fouling...

Polyhydroxyalkanotes (PHAs) are naturally occurring polymers synthesized by a wide range of microorganisms. Their physiological role is to act as carbon and energy reserves, and their mechanical and physical properties are similar to those of petrochemical plastics. PHAs can be synthesized from renewable materials and they are biodegradable....

Winkler, M.K.H. (author)
Book 1 Chapter 1 gives a short overview of the history of aerobic granular sludge technology and finishes with an outline of the thesis. Chapter 2 deals with segregation of biomass as a function of height of the sludge bed. Phosphate accumulating organisms were found to dominate at the bottom of the sludge bed, whereas Glycogen accumulating...

Bassin, J.P. (author)
The removal of nutrients such as nitrogen and phosphorus from both domestic and industrial wastewaters is imperative since they potentially harm the environment. One of the main consequences of excessive availability of nitrogen and phosphorus in aquatic ecosystems (freshwater, marine and estuarine) is the overgrowth of algae and other aquatic...

De Vet, W.W.J.M. (author)
Drinking water production from anaerobic groundwater is usually achieved by so called conventional techniques such as aeration and sand filtration. The notion conventional implies a long history and general acceptation of the application, but doesn’t necessarily mean a thorough understanding of the processes involved. This is certainly the case...

Jiang, Y. (author)
Polyhydroxyalkanoates (PHAs) is a natural bacterial storage compound, which can be used as carbon and electron source. Their remarkable similarities in physical properties to conventional plastics, such as polypropylene, attract great commercial interest. This thesis focuses on PHAs production by bacterial enrichments. As compared to the current...

Areas of research - Petroleum microbiology: Determination of the microbial diversity of oil reservoirs and oil associated ecosystems (wellhead samples and oil field core samples). This research is performed to investigate if microbes can serve as indicators for changing conditions in subsurface environments and if they have a potential use in so...

Nitric oxide (NO) and nitrous oxide (N2O) emissions can be a serious threat to the environment. Rising levels of N2O in the atmosphere contribute to global warming and destruction of the ozone layer. This thesis describes an investigation on the emission of NO and N2O during nitrogen conversion processes. Emissions were measured at wastewater...
