  • Metal Ion Separation Technique Using pH Adjustment And Resin Packed Columns
    Publication number: 20230411029
    Abstract: A waste extraction system includes a precipitation tank comprising a waste stream input, a solution input, and a waste stream output, wherein the waste stream input is fluidly coupled to an upstream segment of a main waste pathway, a column effluent tank, an adsorption column positioned between and fluidly coupled to the precipitation tank and the column effluent tank along the main waste pathway, wherein the adsorption column houses an ion exchange resin and is positioned downstream the precipitation tank, a solution pathway extending from a solution source to the solution input of the precipitation tank, the solution source housing an alkaline solution, and a particle filtration unit positioned between and fluidly coupled to the precipitation tank and the adsorption column.

  • Stepwise Chemical Separation Methods and Systems Using Resin Packed Columns
    Publication number: 20230360815
    Abstract: A waste extraction system that includes a column set positioned between and fluidly coupled to an upstream segment of a main waste pathway and a column effluent tank, the column set having a uranium adsorption column fluidly coupled to a supporting adsorption column along the main waste pathway. The uranium adsorption column is upstream the supporting adsorption column. The waste extraction system also includes a strip waste pathway extending from the uranium adsorption column to the column effluent tank bypassing the supporting adsorption column, an anion exchange resin housed in the uranium adsorption column, and a cation exchange resin housed in the supporting adsorption column.
