Existing mathematical models for aerobic granular sludge have focused solely on lab-scale reactors. In this study, an effort was made to adapt these models to simulate the processes of full-scale installations. The model is the first aerobic granular sludge model to use transient radial diffusion and multiple granule fractions. Aerobic and...

The increase in salinity of groundwater is a global problem (Van Weert et al. 2009). In the west of the Netherlands, seepage of saline and brackish groundwater into layers of freshwater increases the salinity in polders and around drinking water wells (Grakist et al. 2002, Olsthoorn 2008). Systems like PURO and the Freshkeeper abstract brackish...

Nano Filtration (NF) is an advanced treatment process that is able to remove molecules and ions from water using special, synthetic, membrane modules. Under high pressure the so– called feed water enters the membrane module. Part of the water, the permeate, passes through the membrane wall while the rejected ions and molecules are flushed out...

In the application of the Zero Liquid Discharge (ZLD) strategy, not a single drop of water leaves the waste water treatment plant (WWTP). In the recovery strategy of an actual full-scale ZLD WWTP, the focus lies on high quality water, which is fully recovered from reverse osmosis brine (RO-brine). A residual solid stream is generated and...

The actual European Union (EU) guidelines for allowed concentration of arsenic (As) in drinking water fix a maximum of 10 ?g/L. However, this limit is expected to become more stringent: the recommended health related limitation from the US Natural Resources Defense Council is below 1 ?g/L. In Dutch groundwater treatment plants, the produced...

Worldwide 748 million people lacked access to improved sources of drinking water in 2014, of this group almost a quarter relies on untreated surface water (WHO & Unicef, 2014). According to the WHO, simple, socially accepted and low-cost household water treatment systems (HWTS), such as the Ceramic Pot Filter (CPF), can provide a solution for...

Aeration and rapid sand filtration are common practice for the treatment of iron, manganese and ammonium containing ground water for more than a century. Nevertheless, this process has not become obsolete. On the contrary, this thesis assumes that enhanced rapid sand filters remain standard treatment technology in the 21st-century. Iron can be...

Taking into account the growing population, water scarcity is a relevant problem which needs to be addressed. Wastewater needs to be assured by quality, ecosystems protected and the wastewater reuse in industry should be a more common approach that would also assure the reduction of fresh water intake. Dow Chemicals decided to reduce the fresh...

The wastewater infrastructure in Singapore is undergoing a major revamp, which includes the construction of a new water reclamation plant (WRP) in Tuas. This plant aims to maximise the energy recovered from wastewater, with the ultimate aim of achieving energy self-sufficiency. The Integrated Validation Plant (IVP) is a 1000 m3/day pilot plant...

The goal of the research is to determine the potential of laser scanning methods for accurate, non-invasive assessment of the changes in the inner pipe profile of concrete sewer pipes. The main research question is: ‘How accurate is the laser profiler when measuring deteriorated sewer pipes?’ In the research egg shaped concrete sewer pipes were...

Oasen has set itself the goal to “produce water of an impeccable quality and to delivery it flawlessly to its customers”. In formulating this goal, Oasen expresses its concern for unknown pollutants and the increasing concentrations of organic micro-pollutants in its source waters (primarily anaerobic groundwater). To achieve this goal, the...

The necessary removal of organically bound nitrogen and ammonium from sewage conventionally requires energy for aeration and reduces the potential biogas production in the following anaerobic stage due to the required carbon source for de-nitrification. It has recently been demonstrated that fuel cells can generate electricity, using ammonia as...

Introduction COD is one of the most important parameters for wastewater quality. Measuring COD is an expensive and time consuming process. There is a need for an inexpensive, accurate, reliable and continuous technique to monitor COD. Turbidity can be used as a proxy for COD, but is not accurate enough for some applications. Some research...

Surface water is microbiological unsafe, contains too much salts and is polluted with anthropogenic substances like pesticides, medicines, endocrine disruptors and industrial chemicals. The production of safe drinking water out of this water is only possible by applying a robust treatment. A process that can remove virtually all unwanted...

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...

Since several decades organic micro pollutants (OMPs) have been detected in natural waters. Although appearing in very low concentrations (nanograms to micrograms per litre or even lower), the presence of more than 100.000 registered chemical substances in the European Union, of which 30.000-70.000 are in daily use, is a major reason for concern...

The marine/ brackish recirculating aquaculture system (RAS) is a sustainable and environment-friendly cultivating system to meet the increasing demand of aquatic animal protein for the human consumption. However, the increasing amount of aquaculture waste becomes problematic for further application and demands much research attention on it. To...
