Synergistic coagulation of bauxite residue-based polyaluminum ferric chloride for dyeing wastewater treatment

Considering that Fe, Al elements in bauxite residue are active components for water purification, an effective polyaluminum ferric chloride (PAFC) coagulant derived from bauxite residue, with Fe2O3 content > 5.1%, Al 2 O 3 % > 6.5%, basicity > 65%, was successfully prepared. The effect of a...
