NDMA Precursor Control Strategies for Direct Potable Reuse

This project investigated the occurrence, possible sources, and fate of nitrosamines and their precursors in a wastewater collection system, through the biological nutrient removal process and different advanced treatment trains suitable for potable reuse. The research provides a holistic evaluation of N-nitrosodimethylamine (NDMA) and its precursors from the collection system to effluent used for potable reuse, examines the effectiveness of common advanced treatment technologies at the removal of NDMA and its precursors, and offers guidance for utilities that are considering potable reuse and need to evaluate the formation of NDMA and other disinfection byproducts.
