Cost-effective removal of COD in the pre-treatment
Under the optimal operational conditions (pH = 7.5, T = 18 °C) the treatment of wastewater from paper industries by coagulation has led to a reduction of 70% COD for wastewater discharged. In terms of the investigated paper industry wastewater, polyaluminium chloride appears to be most suitable for treatment of high COD concentration.

Coagulation-flocculation is commonly used in the leachate treatment. The objectives of this study were to determine the optimum conditions (dosage and pH) and to compare the performances between single coagulants (polyaluminium chloride (PAC) and tapioca starch (TS)) and dual coagulant (PAC+TS) through a series of jar test.
