Improving the Reactivity of ZVI and NZVI Toward Various Metals and Metal(loid)s with Weak Magnetic etization, respectively. The mechanisms of WMF-induced improvement in contaminant sequestration by ZVI are also summarized. Finally, this chapter identifies the current knowledge gaps and future research needs of WMF/ZVI system for environmental application.

Mechanistic, Mechanistic-Based Empirical, and Continuum-Based Concepts and Models for the Transportsed empirical (correlations to predict NZVI agglomeration and deposition), and continuum-based (Eulerian continuum-based models). These proposed modeling tools can be applied at various scales from column experiments (1-D) to field-scaled operations (3-D) for designing NZVI injection and emplacement

Moving into the Third Decade of Nanoscale Zero-Valent Iron (NZVI) Development: Best Practices for Fdustry gears up for a renaissance of NZVI use. Growing confidence in the use cases for stabilized NZVI, the synergistic application of ZVI + bioremediation and technological advances such as sulfidation will catch the eye of practitioners and site managers into the future and lead to more innovation

Experiences from Pilot- and Large-Scale Demonstration Sites from Across the Globe Including Combineochemical and microbiological conditions favourable for NZVI injection. The synergy between NZVI and bioremediation treatments is discussed along with observed changes in microbiological activity following particle treatments. This chapter also provides highlights of laboratory data needs, general p

Sulfide-Modified NZVI (S-NZVI): Synthesis, Characterization, and Reactivity,ased metal removal capacity, the chemical stability of metal-NZVI is also enhanced through sulfidation. Further, sulfidation is beneficial to heterogeneous Fenton-like reactions. With the presence of dissolved oxygen, S-NZVI generates much more hydroxyl radicals for pollutant degradation through a o

Microbial Perspective of NZVI Applications,ior. It specifically focuses on the reported effects of NZVI on microbial survival and activity, as well as several factors causing the complication of toxicity assessment. The prospects of NZVI-enhanced bioremediation is also discussed. Finally, this chapter presents future research needs in furthe
