Being prepared for the drinking water contaminants of tomorrow: An interdisciplinary approach for the proactive risk governance of emerging chemical and microbial drinking water contaminants

“Access to safe drinking water is a fundamental human need and, therefore, a basic human right. Contaminated water jeopardizes both the physical and social health of all people”: such is the importance of safe drinking water, as stated by Kofi Annan, former Secretary-General of the United Nations, on World Water Day 2001. While some countries...

Hybrid membrane system for desalination and wastewater treatment: Integrating forward osmosis and low pressure reverse osmosis

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...

Subsurface iron and arsenic removal for drinking water treatment in Bangladesh

Arsenic contamination of shallow tube well drinking water is an urgent health problem in Bangladesh. Current arsenic mitigation solutions, including (household) arsenic removal options, do not always provide a sustainable alternative for safe drinking water. A novel technology, Subsurface Arsenic Removal, relies on the existing technology of...

Biofouling of spiral wound membrane systems

Biofouling of spiral wound membrane systems High quality drinking water can be produced with membrane filtration processes like reverse osmosis (RO) and nanofiltration (NF). Because the global demand for fresh clean water is increasing, these membrane technologies will increase in importance in the coming decades. One of the most serious...

Model-Based Control of Drinking-Water Treatment Plants

The drinking water in the Netherlands is of high quality and the production cost is low. This is the result of extensive research in the past decades to innovate and optimise the treatment processes. The processes are monitored and operated by motivated and skilled operators and process technologists, which leads to an operator-dependent,...

Integrated modeling of ozonation for optimization of drinking water treatment

Drinking water treatment plants automation becomes more sophisticated, more on-line monitoring systems become available and integration of modeling environments with control systems becomes easier. This gives possibilities for model-based optimization. In operation of drinking water treatment plants, the processes are usually optimized...

Improving operation of drinking water treatment through modelling

Bijdrage tot het oordeelkundig beheer van het duinwaterkapitaal

Investigation on the use of groundwater storage for drinking water in the dune area near Leiden, Netherlands. Optimization of the ratio of infiltration and extraction of drinking water

Over grondwaterstroomingen bij wateronttrekking door middel van putten

Calculation method for groundwaterflow in case of subraction of groundwater via vertical pumping wells for drinking water purposes. Both permanent and instationary pumping are considered.
