Energy Efficiency Improvement in Pumping Systems

Abstract

Industries, it accounts for 25-50% of energy usage. Pumping has wide range of applications such as domestic, commercial, industrial and agricultural services; a major chunk of the pumping requirement is in Municipal water and waste-water services. The Water Supply system is one of the major functions of urban local bodies in terms of providing pure water to its residents. The energy charges on water supply pumping system also occupy a major portion of the electricity bill. Hence, special attention should be given to energy conservation in the water supply system to minimize the expenditure related to energy consumption, based on the associated energy tariffs. This project focuses towards assessment of Pumping Systems in the Water Treatment and Distribution Plants in Municipal systems as well as Industries by carrying out energy audit to explore scopes of energy efficiency improvement for such systems. EPANET software is used for designing the fluid piping and pumping systems in form of hydraulic network. It can be useful to develop/design new systems as well as its contribution in analysis and improvement of existing system’s performance is also quite creditable. Most optimum configuration for energy efficiency aspect is designed on the basis of various conditions, factors, measurements and afterwards the analysis of such hydraulic systems is done. The pumping system is also evaluated in Pumping System Analysis Tool (PSAT) for determining the actual pump performance, obtaining characteristic pump curves and calculate energy savings. The results of analysis as obtained from both the tools are then verified and compared with measured site data, performance equations and then mathematical techniques are used for justification of these results.
