Resumo

A sustainable, simple, and low O&M approach has been developed using
innovative oxidation chemistries in concert with innovative slow-release deployment
strategies to achieve passive, cost-effective treatment of large chlorinated solvent and
emerging contaminant plumes. This novel remedial technology involves oxidants in the
form of sustained-release permanganate and sustained-release persulfate. Paraffin wax is
used as the environmentally benign and biodegradable matrix material for encapsulating
solid potassium permanganate (KMnO4) or sodium persulfate (NaS2O8) particles.
Sustained-release (SR) oxidants contain ~80% permanganate or unactivated persulfate
and can be formed as cylinders for direct push applications, inserted into holders for
emplacement in permanent or temporary wells. The material may also be chipped/cubed
for hydro-fracturing into low permeability media for treating back diffusion of organic
contaminants. This presentation will provide the results of a variety of experimental and
modeling efforts as well as preliminary results from RemOx® SR ISCO Reagent pilot-scale
field studies.
