The ranges used for the experimental variables were: coagulant dose (83 166 mg L−1 of Al3+), coagulation mixing time (5 30 min), stirring rate (60 300 rpm), contamination level of the wastewater (Wastewater II COD ≈ 2000 mg O2 L−1, Wastewater III COD ≈ 3000 mg O2 L−1), and pH (5 11).

Preliminary results have shown that the synergy technology could cost-effectively treat AR73 wastewater.
