Θέμα: Investigation of impact of TiO2 NPs coated nano-textile wastewater to activated
sludge respiration rate and various bioassays
Prof. Sureyya Meric, Namık Kemal University Tekirdağ, Turkey
Abstract
The use of nanoparticles (NPs) in the textile processes has increased rapidly. However, the negative effects of NPs and the risk of possible release of NPs into the process wastewater and then to aquatic environment are not well addressed yet. In this study, the fate, transport and ecotoxicological effects of sol-gel based TiO2 NPs were investigated in the textile wastewater treatment cycle. FeSO4 and aluminum coagulants were applied under different conditions for the removal of TiO2 NPs from textile industry wastewater. Particle size distribution, absorbance values (UV-Vis range), residual aluminum, iron and TiO2 NPs and soluble COD were monitored to define transport mechanisms during treatment of textile industry wastewater. The effect of TiO2 on activated sludge biological treatment was followed by oxygen uptake rate (OUR), while the ecotoxicity was studied by Ceriodaphnia dubia immobilization test.
Short CV
Dr. Meriç holds BSc., MSc and PhD in Environmental Engineering from Istanbul Technical University, Turkey. She worked as Research Assistant and Assistant Professor at ITU (1988-2004). She was visiting scientist at National Cancer Research Institute, Naples University Federico II (1998-2003) and the University of Salerno, Environmental Engineering Laboratory (2003-2010). Since 2010, she is Professor and head of Environmental Engineering Department and responsible of Environmental Analyses Laboratories at Namık Kemal University. Her research focuses on advanced water and wastewater treatment technologies, impact assessment of xenobiotics, alternative water resources development and management.
