Improving the design life cycle efficiency of wastewater treatment plant inflow pumps Hilary A. Johnson, Kevin P. Simon, Alexander H. Slocum



This paper evaluates data from 10 centrifugal pumps in a large wastewater treatment facility to illustrate the impact of pump design, selection, maintenance, and operation on system efficiency. The paper explores the efficiency impact of several interventions and qualitatively presents trade-offs to implementation. Of the interventions explored, energy savings up to 3% were identified representing 239,000 kWh annually.

Keywords variable speed pumps, pump energy efficiency, pump system optimization, wastewater treatment, product lifecycle, performance metrics
