The Effect of Static Mixer For Aerobic Biogranules Formation For Textile Industry Wastewater Treatment

Two identical sequencing batch reactors (SBRs) namely R1.4N and R1.4Y were operated at superficial air velocity (SAV) of 1.4 cms-1 to investigate the influence of static mixer on aerobic granulation. Reactor R.14Y was added with a static mixer. The formation of aerobic granules with good settling properties were observed in R1.4Y showing SVI and SV of 29.5 mLg-1 and 80.4 mh-1, respectively, with high accumulation of biomass concentration in the reactor (7.18 gL-1). The SBR system also demonstrated good removal efficiency of chemical oxygen demand (COD) and color of 94.2% and 63.1%, respectively. Therefore, it appears that static mixer could enhance the biogranulation process treating textile wastewater
