Organic micropollutants (OMPs) originate from organic chemicals such as drugs and pesticides that are widely used in human activities. OMPs are difficult to remove by conventional water treatment techniques, and hence continue to accumulate in natural water bodies. More effective methods need to be investigated for the removal of OMPs in...

Reusing water is a crucial part of the solution for addressing the growing concern regarding the risk of water scarcity in industrialized and urbanized areas. This study introduces a tool for the design of water networks, focusing on water reuse in industrial parks. Utilizing a mixed-integer nonlinear programming (MINLP) model developed earlier,...

Slow sand filters (SSFs) are essential for ensuring microbial quality and biological stability of drinking water in the Netherlands. However, gaps exist in understanding of removal processes of dissolved organic carbon (DOC) and ammonium and the effects of grain size, loading rate, and backwashing on removal in SSFs.<br/>Four lab-scale SSF...

Groundwater is an essential source of drinking water, and it often contains contaminants in the form of dissolved metal ions that pose health risks and affect its suitability for consumption. Removal of these contaminants by conventional treatment methods, such as oxidation and filtration, results in additional treatment steps for managing...

Groundwater (GW) makes up roughly half of the global drinking water supply. Conventional iron removal in GW treatment produces approximately 10,000t/d of iron sludge. Iron sludge consists of low-density flocs with low to no commercial value and causes frequent energy intensive backwashing of the rapid sand filter. This study aimed to explore the...

Bromate is a possible human carcinogen that does not naturally exist in surface or groundwater bodies. Its formation mostly results from ozonating bromide-containing water during wastewater treatment or drinking water production. Bromate is difficult to remove from water due to its high solubility and low reactivity in the aqueous environment;...

Brine producing industries progressively become the centre of attentionas they carry greater environmental consequences. Despite the extensiveliterature that can be found on desalination, limited information is availableabout the practical comparison of the technologies with regards to the brineconcentration performance and associated energy...

Groundwater is an excellent source for the production of drinking water due to its low concentration of microorganisms and contaminants. The main contaminants present in groundwater are iron, ammonium and manganese, which are sequentially removed in rapid sand filters by a combination of biological and chemical processes. Currently, limited...

For drinking water treatment applications, it is possible to predict the external porosity of an expanded bed of granular activated carbon in fluidized conditions. A new model has been developed with a 2% relative prediction error. <br/><br/>In order to supply sufficient and safe drinking water, water utilities use a treatment train consisting...

In 2013, Brabant Water (BW) adopted a new goal of &lt;1 μg/l for As level in the drinking water, resulting in the need to enhance As removal at seven water treatment plants (WPT’s), including WTP Prinsenbosch (As = 2.6 μg/l). Earlier experiences of BW at WTP Dorst had shown that dosing of NaMnO4 to an aeration-filtration system efficiently...

Water Treatment Plants (WTPs) play a key role in assuring water availability to citizens and businesses. Long term availability of these plants is the interest of the asset manager of a WTP and can be influenced by maintenance strategies and modifications of the system. A WTP is characterized by a complex configuration and repairable,...

This thesis explores the potential to use factories as sources of water and energy for peri-urban industrian contexts in developing countries. The project is situated in Bandung, Indonesia, on the border wall of a large textile factory surrounded by informal settlements. The project transforms the wall of the factory into a public facility that...

Ceramic membranes are gaining more and more attention due to their inherent advan- tages compared with polymeric membranes. Their high thermal, mechanical and chem- ical stability make them more applicable in treating e.g. corrosive and hot wastewater. With their small pore sizes, the ceramic tight ultrafiltration (tight UF) membranes show a...

Ballast water, routinely taken on by ships for stability and structural integrity can contain thousands of mi- crobes, algae and animals. When discharging this ballast water holding these organisms in a non-native ecosystem, new invasive aquatic species can be introduced. This can have to devastating consequences for the local ecosystem. To...

The rapid economic and population growth recently drives Maputo to become more metropolitan, with construction sector as one of the pillars to support its transformation. This progressive move is, however, hindered by one of the most crucial problems: water scarcity. Water is essentially required by construction sector, especially in concrete...

Foams find many applications in the oil industry with their uses ranging from fracturing stimulation treatments to enhanced oil recovery processes. Many of these applications concern the reduction of injected gas mobility which can be induced by a strong foam. However, foam behavior inside a porous medium is complex and a fully predictive model...
