Abstract The chronic effects of titanium dioxide nanoparticles (TiO2 NPs) on aerobic granular sludge (AGS) and algal-bacterial (ABGS) was examined in this study. Sequencing batch bioreactors (SBRs) photo sequencing (PSBRs) were operated with synthetic wastewater containing 0, 1, 5, 10, 20, 30, 50 mg L− 1 TiO2 NPs for 10 days. Nanoparticles at concentrations 1 5 did not impact nutrient removal but led to an increase extracellular polymeric substances (EPSs), primarily protein (PN). With increasing nanoparticle concentration, the negative effect became more pronounced, mainly AGS SBRs. At TiO2, chemical oxygen demand (COD), ammonia-nitrogen (NH3-N), phosphorus (PO43−) decreased by 20.9%, 12.2%, 35.1% AGS, respectively, while ABGS, they reached only 13.4%, 5.7%, 14.2%. ABGS exhibited steady-state 30 after around higher microbial activity EPS content sludge, coupled symbiotic relationship between algae bacteria, contributed tolerance nanoparticles. Finally, although reduced biomass both types bioreactors, accumulation confirmed Energy-dispersive X-ray spectroscopy analysis, absence detectable effluent wastewater, measured Inductively-coupled plasma mass spectrometry, may be attributed specific operational conditions study, including relatively short operation period (10 days) high initial MLSS concentration (6 g 1).
