This project examined the robustness and reliability of treatment barriers that are used in two key process barriers for water reuse, microfiltration and reverse osmosis. The tests were performed at the Scottsdale Water Campus in Arizona. The project involved observing the response of failures in ultrafiltration and reverse osmosis membranes by intentionally breaching the integrity of the membrane. The purposeful destruction of these critical barriers and enhanced operational monitoring during these types of failure are unique. The City’s operations staff were a key resource during these tests since significant involvement from the operations team provided unique insight into the failure events. Test results confirmed that electrical conductivity and pressure decay test are reliable and sensitive monitoring measurements. The results compare key monitoring parameters used for membrane integrity and discuss the sensitivity of these parameters to system changes.
