Inorganic polymeric ferric chloride (POFC) coagulant with proposed structure of Fe4 (Cl2.2OH0.8)4 is synthesized using waste materials and characterized by different tools; XRD, FTIR and SEM. In the current work scrutinized efficiency of POFC for paper mill wastewater (PMW) treatment using response surface methodology (RSM) with central Composite Design (CCD) modeling. Different factors; dose, rapid mixing speed, and rapid mixing time are used for optimize the coagulation process using POFC for treating PMW. The indicators are used for assessing POFC efficiency are turbidity, and chemical oxygen demand (COD) removals. The obtained result of XRD confirms the production of new material of inorganic polymeric coagulants. Based RSM modelling, there is a high correlation between the experimental and predicated removal of turbidity and COD removals. Subsequently, the model is significantly applied for predicating COD and turbidity removals. Conclusively, the obtained results proposed for practical application of POFC coagulant for treatment of paper mill wastewater for COD and turbidity elimination. And the applied RSM with CCD is talented model for optimizing treatment of PMW.
