THE CHALLENGE: In 2008, Murfreesboro Water Resources Department in Tennessee sought to expand and update aging equipment at its Stones River Water Treatment Plant (SRWTP). THE NEED: Located just outside of Nashville, the city's population was rapidly growing and the water treatment plant required additional capacity to meet demand. THE SOLUTION: Upgrading to Pall Water's Aria FLEX system enabled Murfreesboro to meet demand and proactively prepare for anticipated new EPA regulations relating to water treatment while preventing cryptosporidium and giardia lamblia from reaching the public water supply.

THE CHALLENGE: In 2002, Georgia’s City of Flowery Branch faced strict new requirements about discharging water back into the nearby Lake Lanier, which is a drinking water source for the community, compelling the City to find an alternative wastewater system. THE NEED: At the time, the wastewater plant was using conventional sand filters that were unable to achieve the reduction of phosphorus to meet the new limit of 0.13 mg/L. Not only were the sand filters working improperly, but they were creating barriers to the plant’s ability to reach a higher level of treatment and recovery for discharging into the environment. THE SOLUTION: Pall Water's Aria FLEX membrane system was selected due to its critical ability to meet the phosphorus limits. The quality and performance of Pall’s membranes for tertiary treatment were particularly important as this allowed the plant to meet the new permit requirements for phosphorus limits.
