Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...

Noise and vibration present increasing environmental problems to society. Noise and vibration are hazards to human when they occur at high levels, or continue for a long time. High noise levels can cause hearing loss, headaches, dizziness, high blood pressure, loss of concentration, heart disease...etc. There are many researches addressed effect of pumping stations' noise and vibration on perfo...

In district heating stations, the heat carrier is circulated between the energy source and consumers by a pumping system. Fluid handling systems, such as pumping systems, are responsible for a significant portion of the total electrical energy use. Significant opportunities exist to reduce pumping energy through smart design, retrofitting, and operating practices. Most existing systems requirin...

pumps are among the early instruments invented by humans to be taken advantage of in the use of water utilities. design and operation problem of pumping stations is a type of mixed integer non linear programming, in which gradient based optimization methods are not efficient for solving complex problems of this type. in this regard, such evolutionary optimization algorithms as genetic algorithm...
