Awards issued prior to january 20, 2025, were funded under previous administrations and may not reflect the priorities and policies of the current administration.** the overarching objective is to develop design principles for intensified and scalable activated ferrate(VI) treatment (AFT) systems for water reuse in the agroecosystem, with an emphasis for small-scale reclamation facilities. The project teams have complementary expertise in water treatment, water and soil science, and plant nutrition to perform six tasks. Laboratory studies will be implemented to investigate performance and mechanisms of activated FE(VI) reactions with different secondary effluent constituents (task 1). Residuals will be characterized for guidance on management strategies, while an overview on current status and future directions in full-scale ferrate(VI) generation will be developed (task 2). Thereafter, effects of reclaimed water on soil health (task 3) will be assessed (task 4), followed by greenhouse experiments to evaluate impacts on production and quality of selected crops. The results with stakeholder engagement will be input to process intensification-oriented system development to mitigate multiple contaminants, while saving nutrients within proper ranges, in one unit (task 5). Finally, the technology will be comprehensively assessed for right irrigation applications (task 6). This project will be concluded with a workshop to create a version for sustainable and resilient agricultural water reuse. The intensified reclamation process will produce profound environment, economic, and social impacts on the U.S. Agriculture, particularly for small, remote, and/or isolated agricultural communities.
