Abstract
A method for extraction of target components from raw liquid streams includes steps of providing at least one electrochemical cell arranged to support redox reactions resulting in electrochemical change of oxidation states and concentration of at least one ionized target component, and to control at least one pH value of at least one electrolyte in the at least one electrochemical cell; introducing a raw liquid stream comprising a combination of constituent ionic species into the at least one electrochemical cell; operating the at least one electrochemical cell to change concentrations of at least two oxidation states of at least one targeted ionic species from the constituent ionic species; operating the at least one electrochemical cell to maintain a predetermined range of pH of the at least one electrolyte and to eliminate at least one target component pertinent to the at least one oxidation state of the targeted ionic species.
