description Systems for removal of ions from aqueous fluids are provided. In certain embodiments, the present disclosure provides a system comprising a mixing chamber for mixing calcium ions and an aqueous fluid that contains one or more oxyanions; a reactor that receives the aqueous fluid from the mixing chamber, and contains an aluminum metal, where an initial amount of the aluminum metal contained in the reactor is based at least on a calculated corrosion rate, wherein the aluminum metal releases aluminum ions that react with the one or more oxyanions in the aqueous fluid to form a precipitate comprising one or more ettringites; an agitation device to agitate the aqueous fluid and the aluminum metal, one or more measurement devices connected to the reactor, and a controller for operating the agitation device based at least on measurements taken by the measurement devices.
