Pump schedules optimisation with pressure aspects in complex large-scale water distribution systems
(Copernicus Publications on behalf of the Delft University of Technology, 2014-06-16)
This paper considers optimisation of pump and valve schedules in complex large-scale water distribution networks (WDN), taking into account pressure aspects such as minimum service pressure and pressuredependent leakage. ...
Why PRVs Tends to Oscillate at Low Flows
A pressure reducing valve (PRV) consists of a main valve and a PRV controller which senses the output pressure and adjusts the opening of the main valve to maintain the outlet pressure at a given set-point . Although ...
A fast and practical method for model reduction of large scale water distribution networks
This paper presents a method for the reduction of network models described by a system of nonlinear algebraic equations. Such models are, for example, present when modeling water networks, electrical networks, and gas ...
Solving the battle of post-disaster response and restauration (BPDRR) problem with the aid of multi-phase optimization framework
(WDSA / CCWI Joint Conference 2018, 2018-07-14)
The Battle of Post-Disaster Response and Restauration (BPDRR) is a challenging optimization problem which requires the restauration of the B-city water distribution network (WDN) after an earthquake. More specifically, the ...
Interface model between the bioreactor and the membrane in a membrane bioreactor for wastewater treatment.
This paper proposes a structure of an integrated mathematical model of a membrane bioreactor (MBR) and describes the links between two main parts of a MBR model: the bioreactor and the membrane. In case of an immersed MBR ...
Utility-service provision as an example of a complex system
(Emergence: Complexity and Organization, E:CO, 2015-02-01)
Utility–service provision is a process in which products are transformed by appropriate devices into services satisfying human needs and wants. Utility products required for these transformations are usually delivered to ...
