Transformation of beneficially reused aluminium sludge to potential P and Al resource after employing as P-trapping material for wastewater treatment in constructed wetland

► This study focuses on recovering P and Al as potential resources from DASC. ► DASC was employed as substrate in CWs for wastewater treatment. ► Over 99% PO 4 3− could be recovered as hydroxyapatite. ► The remained aluminium could be precipitated as Al(OH) 3 gel or Alg 3. ► All resultant products w...
