Master Thesis Effects of the Odour From Wastewater Treatment Plants on Resident's Living Comfort and Property Values: Case of Narlıdere-Izmir(Izmir Institute of Technology, 2018) Demircan, Gökçe; Özdemir, Semahat; Özdemir, Semahat; Özdemir, Semahat; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyWastewater treatment plants are one of the important technical infrastructure systems in cities. The location of these facilities is at least as important as themselves. Because these facilities can create negative externalities and these externalities can negatively affect people and the environment. The aim of the study is to examine the odour impacts from the wastewater treatment plants on people living around and on property values in surrounding area. In the theoretical framework, the effects of the wastewater treatment plants and similar locally unwanted land uses are examined. In this scope, some examples from the world are searched about the impacts of the negative externalities from this kind of facilities on the health of people living around, their daily life and on property values. Wastewater treatment processes, location criteria of the treatment plants in Europe and in Turkey are analyzed. News published on the internet and complaints on odour impact from wastewater treatment plants are searched both in the world and in Turkey. Compensation forms in accordance with environmental ethics and environmental justice are examined. In this scope, Southwestern Advanced Biological Wastewater Treatment Plant in İzmir is examined. Survey studies were conducted with residents living in the immediate vicinity of this facility. Interviews by questionaries with headman of Limanreis neighborhood, with an environmental engineer working in the treatment plant, and with real estate agents were conducted. At the same time, the effects of the unpleasant odour on the real estate values around the treatment plant were examined with the Hedonic Price Method. End of the study, effects of the unpleasant odour emitted from the Southwestern Advanced Biological Wastewater Treatment Plant in Narlıdere district in İzmir are revealed. It is observed that the odour influences negatively people’s daily life activities, the health of the individuals, quality of the living environment, and property values in the nearby environment.Master Thesis Preparation of Asymmetric Ti̇o2 Based Nano/Ultrafiltration Membranes for Wastewater Treatment(Izmir Institute of Technology, 2017) Odabaşı, İklima; Çiftçioğlu, Muhsin; Çiftçioğlu, Muhsin; 03.02. Department of Chemical Engineering; 03. Faculty of Engineering; 01. Izmir Institute of TechnologyFresh water scarcity have been the most fundamental problem in the world and is already affecting mankind and human activities. This problem forced an increasing effort in the reuse of wastewater originating from municipal, agricultural, and industrial activities. The textile industry demands large amounts of water and produces large quantities of wastewater. Adsorption, filtration, ozonation and photocatalysis techniques are currently used for wastewater treatment and safe discharge to the environment. Although membrane filtration necessitates a high initial setup cost, it has a high potential and may cause significant cost savings through the reuse of water and salts. The membrane based technologies are widely accepted to be the best method when compared with the currently available technologies for wastewater treatment. Extruded tubular alumina supports were coated by stable colloidal sols and polymeric sols prepared by using sol-gel based techniques for the formation of selective micro/ultra/nanofiltration layers in this work. Textile wastewater treatment (with and without pre-treatment) and membrane fouling analysis was conducted. The performances of the membranes were determined through the characterization of permeates by spectrophotometer. The reduction of colors (Pt-Co, m-1), turbidity and suspended solids content were about 99%, 100% and 100%, respectively. The incorporation of a coagulation stage by using Al2(SO4)3 followed by a successive filtration reduced the membrane/irreversible fouling levels in the MF/UF membranes significantly. The Pt-Co 455 values of permeates were determined to be in the 15-260 range which are below the discharge criteria bringing the possibility of the reuse of some of these permeates.
