Measurements and analysis of cavitation in a pressure reducing valve during operation – a case study
(Procedia Engineering, Elsevier, 2015-09-01)
This paper proposes a methodology and presents its practical application for evaluating whether a pressure reducing valve (PRV) is under cavitation during its operation in a water distribution system. The approach is based ...
A Behavioural Membrane Fouling Model for Integrated Simulation of Membrane Bioreactors for Wastewater Treatment
This paper presents a simple membrane fouling model intended for use in conjunction with an activated sludge model to form an integrated model of a membrane bioreactor (MBR). It is based on an earlier development of Liang ...
Efficient energy management of a large-scale water supply system
(Taylor & Francis, 2006-09-01)
Efficient energy management is important for water companies in order to meet economic and environmental targets. For many water supply systems, increased savings can only be accomplished by taking into account the non-linear ...
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 ...
Dynamic optimization approach for solving an optimal scheduling problem in water distribution systems
A new dynamic optimization (DO) approach to solve large scale optimal scheduling problems for water distribution networks is presented. The main motivation of this research is to formulate an algorithm which is significantly ...
Dynamic modeling of pressure reducing valves
(American Society of Civil Engineers, 2003-01-01)
Models are currently available for representing the dynamical behavior of most water network components. Such models are relatively simple, accurate and can be easily solved. However, there is no generally accepted dynamic ...
