Chen, M. (author)
Water scarcity, population growth, and climate change are causing a shortage of water resources globally. Industries are turning to the reclamation and reuse of wastewater, including oily wastewater, which is a major byproduct of oil and gas extraction. The small droplet size of oil-in-water emulsions, however, makes them difficult to remove...

Over the past decades, direct nanofiltration (NF) without pre-treatment has been widely recognized as an alternative for conventional membrane technologies in both drinking water and wastewater treatment, owing to its advantages in energy saving, low chemical usage and high permeate purity. As an alternative, ceramic NF has received growing...

To eliminate organic micropollutants (OMPs) from (surface) water, activated carbon adsorption is a cost-effective technology to remove a broad range of OMPs without producing any byproducts. However, co-existing dissolved organic matter (DOM), at much higher concentrations (mg C/L) than OMPs (ng/L-μg/L), inducing adsorption competition, can...

Groundwater arsenic (As) contamination is a severe drinking water quality problem and threatens human health in Bangladesh and other countries. Chronic exposure to As-contaminated drinking water has resulted in tens of millions of people suffering from skin lesions, hyperkeratosis, melanosis, skin cancer, and cancer of internal organs. The World...

Excessive fluoride (F¯) in drinking water due to natural and anthropogenic activities is a serious health hazard affecting humans worldwide. Groundwater is the major and preferred source of drinking water, also in developing countries. The removal of the excess F<sup>-</sup> from groundwater prior to drinking is important in terms of protection...

Caltran, I. (author)
Natural organic matter (NOM) in drinking water sources causes several problems in water consumption and distribution, and decreases the efficiency of water treatment steps. Ion exchange (IEX) with anion resin can be used to remove NOM in combination with or as an alternative to other techniques, such as coagulation and activated carbon. IEX...

Daniel, D. (author)
Household water treatment (HWT), such as boiling, chlorination, and ceramic filtration, is an interim solution to solve the problem of unsafe drinking water at home, especially for households that do not have access to safe drinking water services. However, previous reports indicate that many people in low and middle-income countries (LMICs) do...

Jiang, N. (author)
A broad range of organic micropollutants (OMPs), including pesticides, pharmaceuticals and personal care products, are present in drinking water sources and effluent of wastewater treatment plants (Kolpin et al., 2002; Stackelberg et al., 2004). The presence of OMPs in water significantly threatens public health and thus calls for effective...

The primary goal of a drinking water company is to produce safe drinking water that meets the quality standards defined in national and international guidelines. Depending on the source water, one or multiple treatment steps are required to produce safe drinking water. Generally, the drinking water treatment plants (WTP) are very robust and over...

Kramer, F.C. (author)
Worldwide population growth, water scarcity, and climate change contribute to an urgent need for alternative water sources for irrigation water, industry water, and, in some countries even, drinking water. The implementation of municipal sewage reclamation is an upcoming trend in water treatment. The use of municipal sewage has the advantage of...

Gude, J.C.J. (author)
Arsenic (As) mobility in water is worldwide studied since its toxicity was proven in 1888. Intake of As can lead to skin disease, cancer, kidney and heart failure, diabetes and paralysis. In the Netherlands, groundwater used for drinking water production contains As in the range from 0 – 70 μg/L. Currently, all groundwater treatment plants...

Gutiérrez, Juan Pablo (author)
Riverbank filtration (RBF) is a surface water filtration method for drinking water through the banks and bed of a river, using extraction wells located near the water body in order to ensure direct aquifer recharge. As the surface water travels through the sediments, contaminants, such as suspended and colloidal solids and pathogenic...

Keuten, M.G.A. (author)
As swimmers enter a swimming pool, they release micro-organisms, particles and soluble substances. While chlorine is often used to inactivate micro-organisms, a side-effect of chlorination is the formation of unwanted disinfection by-products. In order to reduce these by-products, more knowledge is needed on the release of pollutants by bathers...

Sanchez Torres, L.D. (author)
The use of upflow gravel filtration (UFG) is relevant for water supply systems in rural areas and small towns in Colombia, because water quality from surface sources is changing due to the deterioration of watersheds caused by deforestation, erosion, and the discharge of untreated wastewater. These changes are intensified by the effects of...

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...

Moed, D.H. (author)
Boiler feedwater and steam have to be of high purity, because of the susceptibility of the steam-water cycle to corrosion. Organic contaminants break down in boilers by hydrothermolysis, leading to the formation of organic acid anions, which are suspected to cause corrosion of steam-water cycle components. The impact and behavior of organic...

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...
