In this research, a lab scale wastewater treatment plant was locally designed as a continuous culture of activated sludge and using dual water purification system and titanium oxide nanoparticles (TiO2 NPs). Biosynthesis of TiO2NPs and characterization were done, then nanofilter was prepared by tightly wrapping the filter with gauze and moistened it with 1% TiO2 NPs solution until saturation, a control filter was also prepared. Wastewater sample was passed through each filter. The results showed that the TiO2 NPs filter was improved their quality as showed the values of physical, chemical and biological properties of wastewater which included turbidity that decreased from 561 to became 2.9 NTU, the total solid and total suspended solid were decreased from (1820, 1217 mg/l) to (421, 2 mg/l) respectively, the biological and chemical oxygen demands were decreased from (256, 410 mg/l) to became (50, 41.5 mg/l) respectively. The NO3-1, PO4-3, SO4-2 were reduced from ( 100, 8.2, 78) to (6.8, 0.9, 48) respectively. Additionally heavy metals were successfully removed and total plate count, total coliform, total fecal coliform and total fungi were highly decreased.
