Effect of Ca on As release FROM FERRIC AND ALUM RESIDUALS

Dewatering of residuals containing arsenic (As) has attracted little research but will become increasingly important as As is removed from water by sorption to ferric or aluminum hydroxides. Lime conditioning proves to be an effective method for immobilizing As even at high pH. In contrast, increasi...
