On‐site Free‐ammonia Test Helps Prevent Nitrification
This field report discusses a new analytical method for measuring free ammonia, being used by the District of Columbia Water and Sewer Authority (WASA), to efficiently measure real‐time free‐ammonia levels throughout its distribution system to ensure that a safe and stable monochloramine residual is maintained. WASA has found this method to adequately prevent monochloramine decay, which could lead to nitrification in the distribution system. The report provides a brief system overview, and relates WASA's history for free ammonia monitoring, including sampling and testing. The benefits of this new method are discussed, along with its effectiveness at system optimization.
