Ion exchange (IX) is a well-established treatment technology for perchlorate and nitrate
treatment in drinking water application. But this process produces a significant volume of
concentrated waste that requires special handing and disposal. The disposal options for
the residuals are frequently limited by local regulations or are very costly. Therefore, it is
important to develop an effective, sustainable and eco-friendly strategy to deal with
concentrated IX residuals. This paper demonstrates the application of biologically enhanced
acetate-fed fluidized bed reactors (FBR) and hydrogen-fed membrane biofilm reactors
(MBfR) for perchlorate and nitrate reduction from IX residuals. Bench-scale testing
conducted with FBR and MBfR showed almost complete reduction of perchlorate and
nitrate from 3-6% synthetic brine solution. Includes 24 references, tables, figures.
