Higher energy efficiency and better water quality by using model predictive flow control at water supply systems

Half of all water supply systems in the Netherlands are controlled by model predictive flow control; the other half are controlled by conventional level based control. The differences between conventional level based control and model predictive control were investigated in experiments at five full scale water supply systems in the first half of...

Propagation of a cadmium spill through an impounded river system

In this paper, the influence of impoundments (sluices, weirs, etc.) and stream components (tributaries, river branches, associated canals) on the metal content in water and suspended particulate matter (SPM) in the Dutch part of the River Meuse is assessed using the decrease in the cadmium content of the particulate and dissolved phase during...

Diagnosis Report Gouda Wastewater Monitoring Network The Netherlands

Urban pollution managers are being forced to optimize the control of Urban Wastewater Systems (UWwS) in order to deal with more pressure and new criteria for performance. Furthermore, one of the main causes of the deficient control of the UWwSs is the lack of data in each subsystem and the lack of coordination within institutions to share the...

Discolouration in drinking water systems: A particular approach

The quality of drinking water in the Netherlands meets high standards as is annually reported by the Ministry of Housing, Spatial Planning and the Environment (VROM)(Versteegh and Dik, 2006). Also the water companies themselves report in the voluntary Benchmark that water quality is one of the least discriminating factors as all the companies ...

Effects of droughts and floods on the water quality and drinking water function of the river Meuse

The impact of climate change on the water quality of the Rhine river

In this research the effect of hydrological extremes on water quality are studied for the Rhine River, in order to assess potential water quality effects of climate change. The water quality of the Rhine was studied for the periods 1975-1977 and 1987-2005. During these periods eight hydrological extremes occured, five of which being classified...
