The treatability study provided insight on the optimal MetaFix reagent formation and dosing recommendations, which were validated by the site pilot study. The MetaFix reagent dosing of 0.5% was selected for the full scale treatment.
The full scale implementation utilizes an integrated soil treatment mixing system where soil crushing/screening and reagent dosing/mixing can be completed in one process per batch. The treated soils are covered and allowed to react for 7 days.
A lab treatability study was conducted to determine the optimal MetaFix Reagents formulation and dosing rate to treat the highly contaminated soil samples.
A lab treatability study was conducted to determine the optimal MetaFix reagent formulation and dosing rate to treat the four heavy metals of concern: As, Cd, Pb, and Zn.
A lab treatability study was conducted to determine the optimal MetaFix reagent formulation and dosing rate to treat the highly contaminated soil samples with a total arsenic concentration of 21,700 mg/kg.
EHC Metals Reagent is now a part of the MetaFix portfolio of customizable reagents. EHC Metals effectively treated TCE and immobilized Cr(VI) from groundwater to below detection limits at a manufacturing facility in Washington state.
EHC Metals Reagent is now a part of the MetaFix portfolio of customizable reagents. EHC Metals Reagent has been shown to effectively immobilize lead (Pb) from groundwater at a former battery recycling facility in Brazil.
