    Copper (II) Removal from Water by Natural Zeolites
    (SPRINGER-VERLAG BERLIN, 2011) Dursun, Sukru; Argun, M. Emin; Celik, Nazan; Celebi, Fatma
    Clinoptilolite adsorption capacity as a natural matter of the copper (II) ions from artificial polluted water was investigated in this study. In the experimental studies, zeolite mineral which is 25-140 mesh size was used by activating with 0.1 M HCl, and copper ion removal efficiencies were deteimined. Experiences that were under batch condition were studied at different pH values, temperatures and shaking speeds. In the studies, at different pH's; maximum efficiency was found as about 87% at pH 5. Similarly, experiments were carried out at different temperature values, and the maximum efficiency was obtained at 30 degrees C. The efficiency obtained under these conditions is 89.95%. The highest copper removal efficiency was obtained at 200 rpm, and the removal efficiency was measured as 89.62%.

    Heavy metal accumulation in wheat plants irrigated by waste water
    (EDITURA ACAD ROMANE, 2006) Karatas, Mustafa; Dursun, Sukru; Guler, Ersin; Ozdemir, Celaletttn; Argun, M. Emin
    Heavy metals, known as a highly pollutant group with toxic and carcinogen effects, tend to accumulate in living organisms. As the farmers of Konya began to use the wastewate of the dischare, channels for agricultural irrigation, the productive soils have been polluted for a long time period, and the plants growing in the vicinity of the discharge channel were negatively affected. The study investigates heavy metals accumulation in 60 wheat samples collected from wastewater-irrigated fields around discharge channels, during the growth period of plants. Results of this study showed that sewage channel water application for field watering increased the heavy metals (Cu, Cr, Mn, Ni, Pb and Zn) content in the root, body and seed parts of wheat plant, the increases recorded being higher for Mn and Zn.

    Treatment alternatives for micropollutant removal in wastewater
    (Selçuk Üniversitesi Mühendislik Fakültesi, 2017) Nas, Bilgehan; Dolu, Taylan; Ateş, Havva; Argun, M. Emin; Yel, Esra
    Present of micropollutants in aquatic environments has become an alarming environmental problem for both living creatures and environment. Micropollutants, also called as emerging contaminants arise from natural substances and increasing variety of anthropogenic events. Micropollutants consist of pharmaceuticals, personal care products, steroid hormones, industrial chemicals, pesticides, polyaromatic hydrocarbons and other recently seen compounds. These emerging contaminants are commonly found in very low concentration in different water bodies ranging from a few ng/l to several ?g/l. Many existing Wastewater Treatment Plants (WWTPs) in all over the world are not especially designed for removing micropollutants. Low concentration and diversity of micropollutants complicate the dedection and analysis procedures during the treatment processes. Furthermore, entering micropollutants to the WWTPs continuously and stable structure of many micropollutants make difficult to eliminate these emerging compounds sufficiently. Therefore, many micropollutants of unknown concentration pass to aquatic environment from WWTPs. The occurence of micropollutants with a significant levels in aquatic environments disrupt the aquatic ecosystems with a number of adverse effects including short-term and long-term toxicity such as endocrine disrupting effects. Besides the known negative effects of micropollutants there are great number of micropollutants whose effects on living organisms are still unknown. As a result, removing these compounds is of a great importance both to protect environmental ecosystem and human health. Considering that the conventional methods are insufficient for removing the micropollutants other alternative treatment methods including coagulation–flocculation, activated carbon adsorption (powdered activated carbon and granular activated carbon), advanced oxidation processes (AOPs), membrane processes and membrane bioreactor can be applied for better removal. In this study, alternative treatments methods and removal efficiencies of each treatment methods on different micropollutants were investigated and all alternative treatment methods were compared between each other in terms of micropollutant removal rates.
