  • Publication number: 20180251390
    Abstract: Systems and methods for treating spent process water containing sulfate and calcium ions. A treatment method includes adding sodium aluminate to a volume of the spent process water to form a solid precipitate containing aluminum, calcium, and sulfate compounds such as ettringite (Ca6Al2(SO4)3(OH)12.26H2O). The solid precipitate is removed from the process water by clarifying and/or filtration, yielding a disposable solid waste material and a treated process water having concentrations of sulfate and calcium ions significantly lower relative to the initial concentrations in the spent process water.
