Functional zoning of Akcakoca District located along the Western Black Sea Coast of Turkey is achieved by implementing the 'Methodology for Spatial Planning for the Coastal Zone' developed by European Union for coastal areas. The aim of applying the methodology was to realize functional zoning of the district that will eventually lead to spatial planning. In this technique, a typical base map at an appropriate scale and thematic layers are prepared for each of the environmental components for further analyses. The possibility to overlap different layers according to a specified procedure and to realize new theme mapping is a considerable factor while using GIS for the functional zoning. Identical grading system has been applied to each layer formed in order to achieve the overall importance and vulnerability maps of especially the natural components of the district. Functional zoning map is further developed through comparing different layers and current land-use information obtained from satellite imagery coupled with the findings of both the importance and vulnerability analyses. This attempt of applying such a methodology was a significant study as it addressed the decision makers on the multi criteria analyses through the visualized maps of different layers.
Micropollutants such as endocrine disruptors are one of the most important group of chemicals polluting water resources. Conventional treatment systems may not be effective for the removal of endocrine disrupting chemicals (EDCs), and the fate of these chemicals should be carefully monitored in the effluent of wastewater treatment plants (WWTPs). Additional treatment methods such as advanced oxidation processes can be used for the removal of endocrine disruptors. This study presents the existence of endocrine disruptors in 4 different effluents; (i) municipal WWTP effluent, (ii) textile industry WWTP effluent, (iii) organized industrial zone (OIZ) WWTP effluent and (iv) pharmaceutical industry discharge and also presents their removal efficiencies by ozonation and peroxone oxidation. A broad spectrum of removal efficiencies was observed for the EDCs present in the samples since the oxidation efficiency of wastewaters containing EDCs mainly depends on the wastewater matrix and on the type of the EDCs. Ozonation was found to be a low-cost option than peroxone oxidation at the investigated conditions.
This paper presents pilot-scale membrane treatment results performed on biologically treated effluents from fermentation industry and ozone oxidation on concentrates from the same membrane treatment system. The results obtained from the ultrafiltration (UF) and/or the reverse osmosis (RO) systems indicate that membrane treatment are very effective for COD, Color, NH 3 -N and conductivity removal. Ozone oxidation of the membrane concentrates was tested to increase biodegradability of the wastes. The initial ratios of Biochemical oxygen demand (BOD 5 ) to Chemical oxygen demand (COD) were increased significantly by applying chemicaloxidation with O 3 and O 3 + H 2 O 2 .
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
