    Aykaç, Hülya. (Thesis (M.S.)-Bogazici University. Institute of Environmental Technology, 2011., 2011.)
    The main objective of this research is to investigate the effect of Fe doping on TiO2 on the photocatalytic degradation of humic acid and its molecular size fractions in aqueous medium in comparison to the use of bare TiO2. ...
  • Silver inhibition, surface charge and hydrophobicity in activated sludges fed with different substrates 
    Kılıç, Başak. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2014., 2014.)
    Silver is one of heavy metals which is used in many industries. It affects the performance of biological treatment plants because of its toxic effect on microorganisms. The objective of this study is to determine the effect ...
  • Sonolytic and sono-fenton pretreatment of waste activated sludge 
    Savun, Başak. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2011., 2011.)
    The pretreatment of waste activated sludge (WAS) to facilitate solubilization and biodegradability is most common using thermal, mechanical (e.g. ultrasound, high pressure homogenization), chemical (oxidation) and alkali ...
  • Surface interactions of Cs+ and Co2+ with bentonite and perlite 
    Özsoy, Ömer. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2014., 2014.)
    During nuclear weapon tests, any accidents in the nuclear power plants or nuclear fuel cycle generating, considerable amounts of radioactive waste can release very hazardous radionuclides such as137Cs and 60Co to the ...
  • Surface interactions of humic acid - anion doped titania binary system 
    Akan, Aytaç Perihan. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2014., 2014.)
    Humic acids are natural weak polyelectrolytes which play active role in binding mechanism of organic molecules that results in the transportation of contaminants in soils and aquifers. Humic acids constitute the major ...
  • Surfactant sorption & desorption on soil surfaces of varying clay content 
    Küçükaşık, M. Faruk. (Thesis (M.S.) - Bogazici University. Institute of Environmental Sciences, 2001., 2001.)

  • Techno-economic assessment of an integrated algal biorefinery 
    Erdinçler, Begüm. (Thesis (M.S.) - Bogazici University. Institute of Environmental Sciences, 2021., 2021.)
    There is an urgent global need to access sustainable energy sources as the supply-demand imbalance of non-renewable energy resources is one of the most critical issues of humankind. All alternate solutions offered to ...
  • The effect of disintegration by classical and Advanced Fenton Processes on minimization and characteristics of the wastewater sludges 
    Kalkan, Emre. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2010., 2010.)
    Wastewater treatment facilities using biological treatment processes produce large quantity of sludge that must be disposed of safely. In recent years researches focused on sludge minimization, during wastewater treatment ...
  • The estimation of the spatial variability of the flow parameters using hydraulic tomography 
    Demir, Mehmet Taner. (Thesis (M.S.)-Bogazici University. Institute of Environmental Sciences, 2013., 2013.)
    Natural geologic systems are heterogeneous with complex patterns of spatial variability and this heterogeneity strongly influences groundwater flow and contaminant transport. Therefore, the estimation of the spatial ...
  • The fate and transport of some commonly used pesticides in the Konya plain 
    Ongar, Yağmur. (Thesis (M.S.) - Bogazici University. Institute of Environmental Sciences, 2022., 2022)
    By protecting the agricultural products, pesticides are substances that are widely used worldwide to increase crop yields. Although pesticides can have beneficial effects on crop production, these chemicals have various ...
  • The impact of flow connectivity on the interpretation of pumping test data 
    Yetişti, Buse. (Thesis (M.S.) - Bogazici University. Institute of Environmental Sciences, 2020., 2020.)
    The spatial variability of subsurface flow parameters, such as the transmissivity or storativity, is a common feature of all geologic systems. Traditional geostatistical techniques expressed this heterogeneity in terms of ...
