Metal Ion Separation Technique Using pH Adjustment And Resin Packed Columns

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.
