COMBINING PERSULFATE, IN SITU FERRATE GENERATION AND ENHANCED BIOREMEDIATION FOR SAFER, MORE EFFECTIVE REMEDIAL ACTIONS
Moody, W. and J. Mueller.
47th Annual Environmental Show of the South, 16-18 May 2018, Chattanooga, TN. 23 slides, 2018

Provect-OX® is a pre-mixed, dry powder containing sodium persulfate, ferric oxide, and buffer that can be easily applied into a subsurface environment via direct mixing, hydraulic fracturing, pneumatic fracturing, and direct push injection of slurries. Ferrate and sulfate radicals will be continuously generated in situ to support extended oxidation of persistent compounds, provided that persulfate is maintained with iron as an activator. Residual iron and sulfate will support bioremediation processes to manage partially oxidized compounds and residual contaminants that continually desorb from the matrix over time (~3-5 years). This presentation outlines parameters considered for calculating material requirements, discusses field application considerations, and summarizes performance data and costs from example projects. https://www.tn.gov/content/dam/tn/environment/solid-waste/documents/esos/sw_esos-14_2018-05-16-1330-moody.pdf
