Abstract

The paper industry is a complex operating unit with many interactions. Its WASTEWATER contains pollutants and coloured compounds and it is considered to be one of the most contaminated effluents. Several units of wood and paper exist in the world to meet the growing needs of diversified paper products and estimation has shown that paper consumption is growing strongly. In this study, the effect of ALUM and polyaluminum chloride (PACl) coagulants to reduce pollutant concentrations in the industrial PAPER MILL WASTEWATER has been investigated. For this purpose, PAPER MILL WASTEWATER was characterized and the reduction of chemical oxygen (COD), TURBIDITY and sludge volume index (SVI) parameters were evaluated. Optimum dosage of coagulants and pH value are obtained with the standard jar test technique. Under optimum condition, the dosage of ALUM and polyaluminum chloride and initial pH were, respectively, 1000, 500 mg/l and 6. This result reveals that PACl with a 96% removal of TURBIDITY and a 99% reduction of COD could provide the best possible results. Furthermore, SVI reached 250 ml/g when PACl was used as a coagulant. The findings showed that coagulation can be used as a new technology for the treatment of different industrial WASTEWATERs, such as in the PAPER MILL industry.
