This paper addresses the development of a process that is intended to precede and
facilitate the biological degradation of trihalomethanes (THMs) in the treatment train by creating conditions
that allow nitrifying cultures to flourish in the filters, primarily the destruction of
monochloramine using granular activated carbon (GAC). The specific goals of this
research are as follows:
demonstrate the utility of GAC as a suitable media for the reduction of
monochloramine in packed-bed filters under drinking water treatment plant
conditions; and,
determine GAC surface properties that control reduction of monochloramine. A series of continuous-flow activated carbon column studies was performed for a suite of
GAC types, source waters, empty-bed contact times (EBCTs), monochloramine influent
concentrations, and pH values. All studies were run until a
steady-state condition with respect to monochloramine was achieved. Includes 5 references, tables, figures.
