    COLOR REMOVAL FROM TEXTILE WASTEWATER WITH ANAEROBIC TREATMENT PROCESSES
    (Yildiz Technical Univ, 2006) Kaykioglu, Gul; Debik, Eyyup
    In this study, anaerobic treatment of dyes, which are important considerations during the treatment of textile effluents, were determined. Textile effluents have high strength characteristics and have no regulation in the Water Pollution Control Legislation in our country for the color parameter to discharge to receiving bodies. For this reason, textile effluents were generally treated using aerobic treatment and discharged to receiving bodies with high color. However, today, there are some mandatory rules for color removal from industrial wastewater in developed and developing countries. Therefore, studies on color removal were intensively concerned. Anaerobic color removal in reviewed studies was performed using anaerobic or anaerobic/aerobic sequential reactors by anaerobic or facultative microorganisms. It was concluded from previous studies that color removal from textile effluents was successful using anaerobic-aerobic systems in which anaerobic step achieves effective color removal and aerobic step provides additional COD removal. From our reviews, we believe that if anaerobic treatment unit is installed before the activated sludge systems, which were constructed and in operating condition, receiving bodies can be improved to better status.

    Determination of trace elements in soil and sunflower (Helianthus annuus L.) plant parts
    (Parlar Scientific Publications (P S P), 2007) Sabudak, Temine; Seren, Gulay; Kaykioglu, Gul; Dincer, Ali Riza
    Trace elements are currently of environmental concern. They are harmful to humans, animals and tend to bioaccumulate into the food chain. In this study, the concentrations of trace elements in soil and sunflower plant parts have been investigated. The concentrations of copper, manganese, iron, zinc in soil and sunflower plant samples collected from 5 different locations in Corlu, Turkey were determined by flame atomic absorption spectrometry after wet ashing. The maximum concentrations of trace elements per kg soil were 6.37 mg Cu, 0.53 10(3) mg Mn, 1.05 10(3) Mg Fe, and 36.07 mg Zn. The orders of their concentrations in soils and plant parts were found to be Fe>Mn>Zn>Cu. The maximum metal concentrations, except for Fe concentration, were observed in the leaves and seeds of plant parts. In addition, the sunflower leaves collected at locations 4 and 5 were observed for phytotoxic Mn concentration.
