Novel Hybrid Polymer for Wastewater Treatment
A novel ferric chloride (Polyvinylpyrrolidonegrafted-polyacrylamide) hybrid polymer has been synthesized by using ceric-ion-induced initiation technique. The structure and surface morphology of this new hybrid polymer FeCl3-(PVP-g-PAM) have been characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The central composite design (CCD) and response surface methodology (RSM) have been applied in the flocculation process of wastewater treatment to achieve maximum removal efficiency for each of total suspended solids (TSS), turbidity , and chemical oxygen demand (COD), as the other objectives of this study. The operating variables in these experiments are new hybrid polymer dose and wastewater pH. The optimum removal of COD, turbidity, and TSS are 87.8％ , 95.3％ , and 96.3％ respectively when the wastewater pH is 4 and the hybrid polymer dose is 87.6 mg/1. According to these results, wastewater treatment using FeCl3-(PVP-g-PAM) has proven to be an effective alternative in the administration of COD, TSS, and turbidity problems of municipality wastewater.
