Direct application of sewage sludge ash (SSA) to agriculture is mostly prohibited due to its heavy metals and limited bioavailability. Thermochemical treatment of SSA with Cl-donors were carried out to remove heavy metals and enhance P bioavailability. MgCl2 and CaCl2 removed more heavy metal than other Cl-donors. Pb was completely removed followed by Cd, Zn, Cu. They also increased P bioavailability by the conversion of Al-P to Ca/Mg-P which was confirmed by chemical fractionation. XRD confirmed the conversion of AlPO4 to Ca-5(PO4)(3)Cl, Ca-3(PO4)(2), and Mg-3(PO4)(2) by the thermochemical treatment.
