Case Study: Hendersonville, TN
Municipal Water Treatment – Drinking Water | North America: Hendersonville, Tennessee, USA
During the summer of 2007, Hendersonville Utility District’s (HUD) 23-year-old water treatment plant, experienced a particularly severe drought that stressed the capabilities of the plant. In need of a long-term solution, HUD officials were tasked with deciding whether to expand the conventional treatment plant or design and build an entirely new water treatment plant. The solution needed to increase output capacity and incorporate the latest advancements in treatment technologies.
The vision of HUD’s general manager, Tom Atchley, and Board of Commissioners was to build a water treatment plant equipped to provide a plentiful, high-quality water supply for the town for generations to come. With this in mind, it was decided that a brand new, state-of-the-art water treatment plant would be constructed. Following a pilot phase, Pall Water’s Aria FLEX custom water treatment system outperformed competing solutions through its impressive and accurately scaled results, robust membranes, and the professionalism of the Pall Water team.

The Challenge
HUD needed to either expand their conventional treatment plant or design a new water treatment plant to meet regulations and accommodate for a growing population.
-
The Solution
The durability and performance of Pall Water’s Aria FLEX system and its membranes have allowed Hendersonville Utility District’s state-of-the-art facility to produce high quality water that meets all regulations. Designed to accommodate Hendersonville’s population growth and rising water demands for decades to come, Pall Water’s system can increase its capacity to provide an additional 2 MGD of filtered water.
-
The Results
Since opening, the new Hendersonville water treatment plant has realized thousands of dollars in additional cost savings each month as the high recovery rates and quantity of wastewater produced by the membranes have reduced more than 70% of sludge waste compared to the original plant. Additionally, the superior performance of the membranes has also allowed the facility the luxury of periodically taking racks off-line in order to conduct preventative maintenance.

Service & Maintenance: Aria CARE
As the new water treatment plant turned on at the same time the old plant shut down, it was absolutely critical that operators were well-trained, confident, and equipped to run the Pall Water system. Making matters more complicated, operators were using a membrane system for the first time. Key to the smooth transition was an extensive two-week training program that Pall Water technicians provided, both in the classroom and at the old water treatment plant, to ensure operators could confidently run the system independently from day one.
