Against the backdrop of the global water crisis, the pressure for municipalities to efficiently treat water is greater than ever. Water treatment plant operators should regularly analyze the plant’s water treatment performance and ensure systems are operating . Any operating engineer, who typically has a chemical engineering background and who desires to protect his pumps from frequent failures must develop not only a good understanding of the process but also thorough knowledge of the mechanics of the pump. Effective troubleshooting requires an ability to observe changes in performance over time.

1. Introduction. Pump-and-treat (PAT) techniques are often applied to the remediation of dissolved chemicals from shallow aquifers. A related management problem typically consists of the selection of the pumping policy and the most appropriate treatment method, in order to minimize the cost of remediation while meeting a set of technical, economic and social constraints. Work with the Experts. When it comes to your water, don’t take chances. Explore treatment options, and work with a professional to help you make the best decision for your specific water needs.

Elements for Effective Management of Operating Pump and Treat Systems The lessons learned, however, are relevant to almost any P&T system. Therefore, the document may serve as a resource for managers, contractors, or regulators of any P&T system, whether or not that system is within the Superfund Program.
This fact sheet summarizes key aspects of effective management for operating pump and treat (P&T) systems based on lessons learned from conducting optimization evaluations at 20 Superfund-financed P&T systems.

I recommend reference 7, which provides a complete treatment of the subject. However, all the principles for Total Head determination described in this book apply to slurry fluid systems. The only exception is the methods used to calculate pipe friction head.
Centrifugal pumps are by far the most common type of pump used in industrial processes. Juan Reca-Cardeña, Rafael López-Luque, in Advances in Renewable Energies and Power Technologies, Pumping System. Pumping systems are usually composed of one or more than one centrifugal pumps arranged in parallel.
Early PV pumping systems used fixed speed pumps driven by electric motors, and their design and management was considerably simpler. Asset management is the management of the physical components of a drinking water or wastewater system and can include: pipe, valves, tanks, pumps, wells, hydrants, treatment facilities, and any other components that make up the system.
While asset management planning can also include human. In-depth articles on pump industry issues; Pumps. 5 Considerations When Designing a New Pump Test System.

pump and system curves. The operating point will always be where the two curves intersect. Figure 6. Pumps and Pumping System Bureau of Energy Efficiency Figure Pump Operating Point If the actual system curve is different in reality to that calculated, the pump will operate at a flow and head different to that expected.
The first group of pumps operated as 1+1 arrangement (1 operating + 1 standby) during the first year. It ran at low speed. Five pumps were needed in the second year (two existing VSD pumps and three new pumps). These operated in 3+2 arrangement (3 operating + 2 standby).
Each pump provides a capacity and head of 2, m3/h and 60 m, respectively. Centrifugal Pumps •Develop pressure by increasing the velocity of the liquid •Liquid is literally flung out of the cutwater.
Positive Displacement Pumps •Allow liquid to flow into an open cavity •Trap the liquid in the pump •Transport liquid from the suction to discharge port •Mechanically force liquid out of the pump.
Researchers at the U.S. Department of Energy’s Pacific Northwest National Library recently released a paper on the Performance Assessment of Pump-and-Treat Systems. The pump-and-treat (P&T) remediation technology is comprised of three main aspects: groundwater extraction for hydraulic control and contaminant removal, above-ground treatment, and groundwater monitoring to.

The results showed that the moving-well model provided a more effective solution to the well location problem than did fixed-well formulations.

Communi-ties may also need to be educated about protecting water sources from animal or human contamination, and mobilized. It should be emphasized that all the positive effects of a water-treatment system could be jeopardized if the water is not drawn, stored and trans. discharged. The treatment method depends on the physical-chemical properties of the contami-nants to be removed.
This remediation scheme is known as pump-and-treat (P&T). P&T systems are designed to: (1) Hydraulically contain and control the movement of contamina-ted groundwater and prevent continued expansion of the contamination zone.
1 Diagram depicting the general pump-and-treat scenario where a source zone results in a dissolved phase plume, extraction wells are used to intercept the contaminant plume, and contaminated water is treated in an aboveground treatment system prior. Controls can also provide system monitoring functions to ensure that pumps are operating at the optimal point.
Time can reduce pump operating efficiency for example with impeller wear. Monitoring energy consumed provides feedback on such events and allows the end user to better maintain optimal operating performance.Pump-and-treat systems can be designed for two very different goals: containment, to prevent the contaminant from spreading, and restoration, to remove the contaminant.
In pump-and-treat systems designed for containment, the extraction rate is generally established as the minimum rate sufficient to prevent enlargement of the contaminated zone.
