Efficient operation of effluent pumps at water and wastewater treatment plants is critical. These days, with energy costs skyrocketing, inefficiency in pumps operation presents real and significant challenges to the plant management.
Equipment reliability is a must in small towns like Dunn Center, N.D., where Goulds Pumps turbines and Aquavar controllers are in demand.
Proper selection, installation and maintenance are the key elements in maximizing pump life
My goal is to help you better understand the misunderstood “chemical feed pump.”

Using Metering Pumps and Degassing Valves
in Industrial Water Treatment Systems
The purpose of this paper is to discuss utilization of flow-controlled pump stations as a method to reduce distribution system leakage and, as an additional benefit, reduce power costs associated with the more traditional constant pressure systems. Though conceptual, this article discusses in general terms pump station controllers that are being used to track the varying pressure requirements in distributions systems. By anticipating those requirements based upon flow, modern day pumping systems controllers can provide smooth-flow systems that meet the minimum pressure requirements.

Although the pump is a relatively small part of the overall cost of an RO system, expenses resulting from downtime and inefficiency quickly can diminish the productivity of the system and your return on investment. Due to the corrosive atmosphere and high demands on these sea water RO systems, special attention is required in the pump selection process. There are several key factors that will help to ensure optimum pump and system performance.
Costly, time-consuming and persistent maintenance problems, coupled with unacceptable odor levels, prompted a major southwest wastewater treatment plant to scrap its sludge handling system.

The Cupertino Sanitary District (CSD) recently underwent significant equipment upgrades at its lift stations. The district's submersible pumps now operate with a new type of impeller designed to virtually eliminate blockages. During the year following the pump retrofit program, the utility saved several thousand dollars by preventing all but one blockage. Additional energy savings are being realized due to the suspended high operating efficiency offered by the new pumps.
