Redox^Sx40

Redox^Sx40, a proprietary calcium / sodium polysulfide formulation, has nearly twice the treatment capacity when treating Chromite Ore Processing Residue (COPR) contaminated wastes compared to traditional 29% calcium polysulfide. 

Redox^Sx40 has been successfully used in the commercial treatment of COPR contaminated soils at a RCRA Part B permitted hazardous waste treatment facility and may also be used for ground water remediation of heavy metals and for soil remediation either ex-situ or in-situ.

FerroBlack-Hybrid

FerroBlack-H is our proprietary reagent that contains both soluble and insoluble sulfides. Since the soluble sulfides (S^-2) and insoluble sulfides are in equilibrium, the soluble sulfides allow for the immediate treatment of available heavy metals, while the insoluble sulfides (FeS) remains where placed, allowing for long-term stabilization and/or reducing capacity as additional heavy metals come in contact with the insoluble sulfide in the future.

In waste streams containing mixtures of heavy metals at various concentrations and valence states (e.g. Cr, Cd, Ni As and Sb), the soluble sulfides, insoluble sulfides, and their various associated reaction products (e.g. Fe⁺² + Fe⁺³)react sequentially as the system's dynamics change, thus enabling our customers to achieve their treatment objectives, initially and over the long term.
