Micropollutants are persistent, toxic, and mostly bioaccumulative contaminants that cannot be removed completely by conventional wastewater treatment techniques. It has been observed that these pollutants, previously thought to originate from industrial discharges, also emerge from urban wastewater treatment plants (UWWTPs). The EU Legislation, which Turkey tries to harmonize, considers the micropollutants and aim to reduce their occurrence in the aquatic environment. This research was carried out to estimate the total installation and annual operation and maintenance costs, which are needed for upgrading UWWTPs in Turkey to reduce the levels of micropollutants. As treatment options; ozonation, activated carbon adsorption, and membrane filtration technologies were considered and the most appropriate treatment technology for selected 20 UWWTPs was determined with respect to effluent micropollutant characteristics. Based on the cost data compiled from the literature, the total installation and annual operation and maintenance costs for the 20 UWWTPs were calculated. The additional treatment needed was identified as nanofiltration for 11 plants, ozonation for six plants, powdered activated carbon for two plants and reverse osmosis for one plant. The installation cost was estimated as $68,234 to $572,693,000 for the 20 UWWTPs. The results were then extrapolated to Turkey, and the associated installation cost was estimated to vary from $ 87,6 million to $ 26,6 billion.

Optimization of windrow food waste composting to inactivate pathogenic microorganisms Çekmecelioğlu, Deniz; Graves, RE; Davitt, NH (2005-09-01) Composting is a popular means of treating organic wastes, and properly controlled composting can destroy the pathogenic microorganisms present in wastes for a human- and environment-friendly end product. Therefore, optimization of windrow composting of food waste, manure, and bulking agents was evaluated for maximum pathogen inactivation (Salmonella and E. coli O157:H7). Seasonal effects on reductions of Salmonella and E. coli O157:H7 according to the compost temperatures were studied (90 to 150 days). Feca...
Fate and degradation kinetics of nonylphenol compounds in aerobic batch digesters Omeroglu, Seçil; Sanin, Faika Dilek (2014-11-01) Nonylphenol (NP) compounds are toxic and persistent chemicals that are not fully degraded either in natural or engineered systems. Current knowledge indicates that these compounds concentrate in sewage sludge. Therefore, investigating the degradation patterns and types of metabolites formed during sludge treatment are important for land application of sewage sludge. Unfortunately, the information on the fate of nonylphenol compounds in sludge treatment is very limited. This study aims to investigate the bio...
Influence of nickel (II) and chromium (VI) on the laboratory scale rotating biological contactor Taseli, B. K.; Gökçay, Celal Ferdi; Gurol, A. (Springer Science and Business Media LLC, 2008-09-01) High concentration of heavy metals is toxic for most microorganisms and cause strict damage in wastewater treatment operations and often a physico-chemical pretreatment prior to biological treatment is considered necessary. However, in this study it has been shown that biological systems can adapt to Ni (II) and Cr (VI) when their concentration is below 10 and 20 mg/L, respectively. The aim of this study was to evaluate the effect of Ni (II) and Cr (VI) on the lab-scale rotating biological contactor process...
Current status of filtration theory Yukseler, H; Yetiş, Ülkü; Tosun, I (2005-10-01) Sludge dewatering is a difficult process in water and wastewater treatment, as commonly achieved through filtration practice. The purpose of sludge dewatering is to remove as much of the liquid portion of the sludge so that its transport and disposal becomes possible and feasible. The extent of the performance of the filtration operation is highly influenced by the characteristics of the sludge; such as its solids concentration, bound water content, organic content, cellulose content, pH, electrical charge ...
Evaluation of Turkey's status in terms of compliance with the requirements of the Stockholm convention Şıltu, Esra; İmamoğlu, İpek; Department of Environmental Engineering (2014) Persistent Organic Pollutants (POPs) are stable, toxic compounds released into the environment due to anthropogenic activities. POPs can accumulate in fatty tissues of living organisms and become concentrated up the food chain, posing a serious threat to environment and human health. Once they are released, POPs participate in long-range transport and can have a widespread effect. Stockholm Convention on POPs, which was adopted in 2001 and entered into force in 2004, is a global treaty to take measures agai...
