Strategy to Transition from an Intermittent to a Continuous Water Supply Using a District Metering Area Approach

In this thesis, I develop and evaluate a demand-side approach to transition from an intermittent to a continuous water supply using a district metered areas approach in Accra, Ghana, an urban metroplex of 4.0 million persons in western Africa. Intermittent water supply (IWS) is inherently inefficient. These systems foment health hazards and are...

Smart Water Meters in Full-scale Drinking Water Distribution Networks (DWDNs)

For drinking water companies in Netherlands, the current conventional treatment technique may not be fully capable to cope with potential future problems resulted from climate change, salinization and social developments, such as population growth. Innovative technologies like reverse osmosis and more strict drinking water standards are expected...

Fluidization behavior of granular activated carbon: For drinking water treatment applications

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...

Thermal Energy Recovery from Wastewater at the TU Delft Campus

In order to reduce the emissions of CO2 and other greenhouse gasses, sustainable development is gaining in importance in the recent years. This is also the case for TU Delft. The sustainable advancement requires renewable energy sources that do not require fossil fuels. The wastewater flow is currently not utilised as a renewable energy source...

The Study of Potential Transition Effects on Water Quality During Distribution by Smart Water Meters (SWMs)

Driven by the fast development of water purification technologies, tightening of water quality regulations and the increasing public concern on water-related health problems, drinking water companies have spared no efforts on treatment processes upgradation as well as striving on maintenance aspects. In the event of perturbation such as supply...

Optimising the Ripening Period of Slow Sand Filters

This work is carried out in collaboration with Dunea and TU Delft. The aim of this study was to optimize the ripening period of slow sand filters and to identify the indicators of ripening. Combination of full scale and column scale slow sandfilters...

Organic Micropollutant Treatment by Pre-Ozonation and Activated Carbon

Inadequate treatment of wastewater effluent is one of the major point sources of pollution of organic micropollutants (OMPs) into aquatic environments. Wastewater treatment plants need to be upgraded to reduce OMP contamination. Recently, the combination of pre-ozonation and granular activated carbon (GAC) filtration has been proposed as a...
