This paper presents a study conducted on reuse water from the Gibson Island Advanced Water Treatment Plant (AWTP) in Brisbane, Australia, to determine if different chloramines dosing conditions affect the formation potential of N-Nitrosodimethylamine (NDMA). The Gibson Island AWTP has an NDMA treated water goal of less than 10 ng/L. This limit was established as a result of the plant being a high level reuse facility. Because the effluent supplements the region's water supply reservoir, potential accumulation of microconstituents is a public health concern. Bench-scale evaluation of NDMA formation while using chloramines was a key component to establishing appropriate design criteria. The objective of this paper was to provide information regarding bench-scale formation of NDMA when both preformed and sequential chloramination are employed, and the impact of pH on NDMA formation. Includes 12 references, table, figures.
