Case Study: Murfreesboro, TN
Municipal Water Treatment – Drinking Water | North America: Murfreesboro, Tennessee, USA
In 2008, Murfreesboro Water Resources Department in Tennessee sought to expand and update aging equipment at its Stones River Water Treatment Plant (SRWTP). Located just outside of Nashville, the city's population was rapidly growing and the water treatment plant required additional capacity to meet demand. The upgrade also gave Murfreesboro the opportunity to proactively prepare for anticipated new EPA regulations relating to water treatment while preventing cryptosporidium and giardia lamblia from reaching the public water supply. After evaluating numerous membrane filtration systems, Pall Water's Aria FLEX custom water treatment system was selected because it can meet high safety standards for water quality and operator safety.

The Stones River Water Treatment Plant (SRWTP) in Tennessee wanted to expand and update its aging water treatment equipment, and proactively prepare for new EPA regulations. Natural conditions, turbidity, and water hardness in the Murfreesboro area posed additional treatment challenges for the SRWTP expansion project.
When the plant update and expansion project was initially conceived, membranes were coming to the forefront as the most reliable, highest quality filtration technology. Compared to sand filtration, which SRWTP previously used, membrane filtration allows the plant to more effectively control cryptosporidium and giardia lamblia at a lower cost and with an absolute barrier to the protozoans.
When the upgraded Stones River Water Treatment Plant opened its doors in 2008, it was operating at the highest flux rate in the country. Following nearly a decade of operation, Pall Water's Aria FLEX system is still running strong. With clean-in-place (CIPs) conducted monthly, the membranes are able to recover and perform at the same standards as when they were placed in service in 2008.

Watch Our Story:
Initially intrigued by the opportunity to reduce membrane costs, the SRWTP swapped out one train of Pall Water membranes with a competitor who was willing to match Pall Water's warranty. The replacement membranes were operationally comparable, though a mere seven months into testing and the membranes experienced significant drops in permeability while flux rates fell within hours of cleaning.
The continued decline of the competitor’s membranes led SRWTP to reinstalling Pall Water’s proven, hollow-fiber membranes. Watch our video to learn more about this project, and see Pall's trusted membranes in action.
