Ferrate(VI), though well-acknowledged for its multiple treatment functions, has traditionally found application in an auxiliary treatment of conventional water treatment trains, primarily targeting specific contaminants. However, the reactor configurations and system operations developed from this traditional approach are not optimally suited for harnessing its full multifunctionality. In contrast, an alternative process integration approach, such as process intensification, can allow for the tailored development of modular, multifunctional ferrate(VI) reactors capable of achieving various treatment objectives within a single unit. This perspective article critically analyzes and compares the two distinct development approaches for ferrate(VI) technology in water treatment. We argue that the process integration pathway represents a promising approach, given that it facilitates the reactor design to accommodate different ferrate(VI)-driven treatment processes and their interactions, while potentially accomplishing enhanced treatment efficiency, reduced costs and energy consumption, and a smaller physical footprint. The resulting system intensification and adaptability have the potential to drive technological innovation and revolution in water treatment for achieving water security.
