AFE July/August 2012 : Page 23Another benefi t associated with fl u-orescent-traced product systems is that the inhibitor level can be continuously monitored online in real time. When coupled with a web-enabled controller, a traced product system will continuously monitor and log the cooling tower’s inhibitor level, then initiate an email alarm whenever it is out of range. Th is capability greatly reduces the time it takes to identify and correct a major chemical feed problem, such as a pump losing prime or a feed tank running out. It also allows the inhibitor level to be monitored and data logged in real time as can be done with other key control parameters, such as conductivity, pH, ORP and water usage. Th is data can be used to continuously monitor and adjust the water treatment program based on changing system demands. IMAGE 2 Traced Product Feed and Control System. Image courtesy of Chem-Aqua Fluorescent Tracing Makes Testing Easier Trace levels of molybdenum (Mo) are often added to cooling water inhibitor formulations to provide a relatively easy way to determine the treatment level in the system water. Currently, the operator must sample the system water and perform a two-to three-minute wet chemistry test for Mo that < Take your professional development and networking to the next level...Join AFE Toolkit for SUCCESS > CAREER-FOCUSED NETWORKING Gain access to solutions and best practices, events and opportunities to connect with fellow leaders and peers in facilities engineering.
