Abstract: Methods, systems and apparatuses are disclosed for treating aluminum desmutting solutions by reacting, mixing and filtering an aluminum desmutting solution flow from an aluminum desmutting solution tank and controlling the amount of copper ions in an aluminum desmutting solution tank by directing a portion of the desmutting solution from a desmutting solution tank to a treatment line, reacting a portion of the desmutting solution in the treatment line and recirculating a filtered aluminum desmutting solution to the aluminum desmutting solution tank during active desmutting operation of the aluminum desmutting solution tank.
