Özet

In this study, the principles of chemical precipitation of sulfate which is based on the formation of ettringite, a double salt with the formula Ca₃Al₂O₆.3CaSO₄.32H₄O are evaluated. The Al₂(SO₄)₃-Ca(OH)₂-H₂O system is chosen to study the equilibrium equations for ettringite precipitation. The residual sulfate concentrations are below 200 mg/1 in pH values above 10,5 indicating that ettringite precipitation can be employed as an alternative treatment process for the removal of sulfate ions.
