Developing effective methods for treating waste brines to enable reuse is economically and environmentally beneficial. Studies demonstrated biological denitrification in high salt solutions, enabling reuse of waste brines for resin regeneration (Lehman et al., 2008). Clifford and colleagues demonstrated heterotrophic biological denitrification in a bench-scale sequencing batch reactor, allowing reuse of waste brine for at least 15 cycles of IX resin regeneration and reducing brine waste volumes and salt requirements by 90% and 50%, respectively (Clifford and Liu, 1993a and Clifford and Liu, 1993b). However, biological treatment of waste brines presents its own challenges, including slow start up times biochemical reactions make intermittent treatment applications problematic, and the unpredictability of the bacterial culture in the presence of non-target water constituents (Lehman et al., 2008).
