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. Working Group I...

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...

Het probleem in Beira (Mozambique) is dat de stad een matig- tot sterke bevolkingsgroei kan verwachten tot en met 2035. De huidige drinkwaterzuivering staat 100 km van de stad af door verzilting van de Pungue-rivier. Uiteindelijk is het gunstiger gebleken om de hoofd-transportleiding te vervangen en de zuivering uit te breiden, in plaats van een...

Van Rijswijk, M. (author)
This graduation thesis researches the benefits of using natural wastewater purification as a spatial development strategy on a, still unexplored, large scale. Novi Sad functions as a case study for the theoretical & design reflection of the application of large scale wastewater purification by using natural techniques. The city is located in the...

Increasingly, harbour activities in the harbour of Rotterdam are moving west towards the Northsea (Maasvlakte I & II). This impoverishes harbour areas close to Rotterdam like the Stadshavens area. The municipality of Rotterdam is trying to revitalize these areas by transforming them into sustainable living and working communities. Evides N.V. is...

The main objective of the thesis is to develop a design for a vertical green facade with integrated wastewater treatment. Vertical green systems provide a highly versatile type of facade that upgrades equally the building and it’s surroundings. The lack of quantitative benefits though, limit the motives for installing green facades to...

Despite continuous developments in the field of MBR technology, membrane fouling together with the associated energy demand and related costs issues remain major challenges. The efficiency of the filtration process in an MBR is governed by the activated sludge filterability, which is still limitedly understood and is determined by the...

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...

In this research a considerable amount of scientific evidence had been collected which leads to the conclusion that the urban wastewater components should be designed as one integrated system, if the protection of the receiving waters is to be achieved cost-effectively. Even more, there is a need to optimize the design and operation of the...

The removal of nitrogen from wastewater is a costly and high energy demanded process. Not only in wastewater treatment facilities but also in the livestock sector nitrogen removal is costly. In this study the removal of nitrogen from wastewater by converting to ammonia to be fed as a fuel to a Solid Oxide Fuel Cell (SOFC) is treated. Ammonia is...

Phosphorus depletion is an emerging and serious global environmental issue. At this moment, research and policy discussion on phosphorus scarcity is still limited. This research investigates the possibilities of phosphorus recovery by controlled precipitation of struvite from digested sludge. At Waternet’s wastewater treatment plant Amsterdam...

Several wastewater stabilization ponds (WSP) in Tunisia suffer periodically from the ‘red-water’ phenomenon due to blooming of purple sulfur bacteria, indicating that sulfur cycle is one of the main element cycles in these ponds. In this study, we investigated the microbial diversity of the El Menzeh WSP and focused in particular on the...

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...

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...

Clean water is becoming a scarce resource. As a consequence reclaimed wastewater can be an attractive alternative to replace existing water resources for non-potable reuse options. In order to achieve this goal advanced treatment technologies are required. An example of such technology is the membrane bioreactor (MBR) process. In the MBR process...

Ravazzini, A.M. (author)
In the usual wastewater treatment schemes the application of membranes follows a biological process. However, ultrafiltration of untreated wastewater produces permeate free of particles and bacteria in one single step and could represent the starting point for new water-reuse concepts. This thesis focuses on crossflow ultrafiltration of raw...
