The Long Beach Water Department (LBWD) is conducting comprehensive research to
evaluate seawater desalination integration issues. Although distribution system
corrosion has historically been the main concern with integrating desalinated seawater,
recent research has identified a detrimental phenomenon associated with rapid loss in
disinfectant residual when chloraminating desalinated seawater. This residual instability
not only reduces the system's ability to suppress microbial activity, it also raises
concerns with nitrification. In addition, the need to rechlorinate to recover the residual
loss can impact disinfection byproduct (DBP) formation, as presence of higher bromide
coupled with natural organic matter in the system may result in substantial formation of
DBPs. Extensive bench top evaluations were performed using various synthetic waters
and end-quality desalinated seawaters to understand the behavior of chloramination of
waters containing bromide and to quantify extent of the residual stability impacts. The
results of these investigations are discussed in this paper. Includes 11 references, table, figures.
