This paper presents some aspects concerning the estimation of the parameters in the input-output chlorine residuals models of drinking water distribution networks (DWDNs) used for transportation of treated drinkable water from the water treating plants to consumers. To kill the microorganisms that can cause the waterborne ills, disinfection is usually the final treatment stage in the drinking w...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...

Leakage detection is an important task to ensure the operational safety of water distribution networks. characteristic extraction based on high-frequency data has been widely used for leakage in experimental However, accuracy single-feature-based methods limited by interference background pressure fluctuations In addition, setting diagnosis thresholds insufficiently studied, but influences perf...

Despite the growing concern of water companies throughout the world to have available water resources, which is strongly related to leakage control is not always properly considered within water management companies. Nowadays, the continuous monitoring of water distribution systems is a prerequisite towards the rapid and efficient detection of any abnormal situation. Within European Union prior...

This research involves the design and analysis of pinch-based water/wastewater networks to minimize water utility in the petrochemical and petroleum industries. A study has been done on Tehran Oil Refinery to analyze feasibilities of regeneration, reuse and recycling of water network. COD is considered as a single key contaminant. Amount of freshwater was reduced about 149m/h (43.8%) regarding ...

Abstract Acoustic sensors are widely deployed to detect hidden leakages in water distribution networks (WDNs). However, few studies have been conducted quantitatively understand the dominant leakage acoustic characteristics, which usually mixed with unknown environmental noises, coupled constraint of sparse deployment sensors. In this paper, a comprehensive approach, that performs data feature ...
