1、Technology Solutions toAddress Future Cleanup ChallengesRadWaste SummitJune 11-12,2025Savannah,GeorgiaPresented by:Gary J.Meyer,Chief Technology OfficerRedox SolutionsRedox owns and operatesthe only chemical plant in North America that custom synthesizes treatment reagents,trade named FerroBlack.Red

2、oxs family of FerroBlackreagents can be customized to contain:Mackinawite-structured iron sulfide(FeS),Layered double hydroxides(LDH),Excess sulfides(S),or polysulfides(SX).Redoxs reagents meet the definition of”Green Chemistry”of both the United States EPA and the ACS(Green Chemistry Institute).Who

3、 We AreWhat We DoFor the past 20 years,Redox has provided solutions to consultants,engineers,and environmental contractors for the treatment of metals and/or chlorinated hydrocarbon contaminated:Soils Groundwater Wastewater Vapors/Gases Solids(e.g.,debris,slags)There is no“one size fits all”solution

4、.Each reagent design is based on factors such as:Contaminant(s)of concern pH ORP Site geology We perform baseline analytical testing on samples provided by the client.We then synthesize a reagent in our laboratory,perform treatability testing,and run analytical testing to confirm success.This proces
