Advanced treatment process of secondary waste solution of HyBRID decontamination agent

The aim of this study was to establish the treatment process of decontamination waste solution by using chemical precipitation method. Chemical precipitation that solute dissolved in a solution precipitates out on a carrier that forces it to bind together is proven technology for the removal of metals, other inorganic compounds, and suspended solids. The waste solution treatment of HyBRID decontamination agents was developed by adding Ba(OH)₂ as BaSO₄ precipitation process. We observed the high sulfate removal efficiency with metal ions except for potassium ions. For the BaSO₄ separation, we have optimized the separation process condition according to effective parameters. Our waste treatment strategy would be beneficial for lower waste volume and cost.
