The aim of presented study is the investigation of clay minerals utilization in the wastewater treatment. The chemical treatability studies were carried out by the refined packing type kaolinite (hydrate aluminum silicate). By testing kaolinite as coagulant and flocculant separately within the experimental studies, optimum doses were determined, and on the basis of treatment efficiencies, results were compared with the chemicals such as alum, lime and ferric chloride which are widely used. The removal of organic matter was deter-mined according to Chemical Oxygen Demand (COD) parameter. Higher treatment efficiencies were obtained when kaolinite was used as flocculant. For the domestic wastewater, 82% organic matter, 70% suspended solids matter, and 23% oil-grease removals were achieved when alum was used as coagulant and kaolinite was used as flocculant. The turbidity of wastewater was removed completely, and insignificant differences were observed in pH parameter. For industrial wastewater samples, the highest efficiency was obtained when ferric chloride was used as coagulant and kaolinite was used as flocculant. In this case, 99% organic matter, 83% suspended solids matter, and 85% oil-grease removals were obtained. For the industrial wastewater treatment, the usage of kaolinite as coagulant yielded also efficient results, 96% COD removal was obtained.

Comparison of Fenitrothion and Trifluralin Adsorption on Organo-Zeolites and Activated Carbon. Part II: Thermodynamic Parameters and the Suitability of the Kinetic Models of Pesticide Adsorption
LÜLE ŞENÖZ, Güzide Meltem; Atalay, Mustafa Ümit (Informa UK Limited, 2014-07-04)
The suitability of two kinetic models and the thermodynamic parameters of pesticide adsorption were investigated based on obtained data of previous studies. Kinetic evaluation indicated that the pesticides adsorption on adsorbents followed the pseudo-second-order model. Gibbs free energy (Delta G degrees), enthalpy (Delta H degrees), and entropy (Delta S degrees) were calculated for thermodynamic parameters by using linearized Arrhenius equation. The results indicated that the sorption process of fenitrothi...
Dehydration of alcohol solutions obtained from a solvent recovery process by pervaporation
Büküşoğlu, Emre; Yılmaz, Levent; Department of Chemical Engineering (2010)
Solvent recovery is gaining importance in the chemical production processes to reduce the costs and because of environmental concerns. Therefore separation schemes for recovery and recycle of solvents used in printing and packaging industry were developed. However, a low value by-product, mainly ethyl alcohol and isopropanol, is obtained during the solvent recovery process. If the water concentration of this mixture is decreased below 0.1% by weight, the value of it increases significantly. To dehydrate thi...
Flow sheet optimization by the concept of sustainable development: alumina industry
Kurucak, Abdurrahman; Gürüz, Güniz; Department of Chemical Engineering (2010)
In this study, effects of changes in various parameters of the Bayer process on the amount of “red mud”, which has many environmental drawbacks, were examined in accordance with the principles of “sustainable development”. The production process of Seydişehir Aluminum Plant is modeled as a case study. First a steady-state mass balance calculation is carried out by incorporating sequential modular approach. Then a model of the Bayer process digester is programmed and several simulations are carried out using...
Treatment of Effluents from Hemp Based Pulp and Paper Industry I Waste Characterization and Physico chemical Treatability
Dilek, Filiz Bengü (1993-10-15)
This study was conducted to determine the wastewater characteristics as well as the treatment alternatives for the Tafkopru Pulp and Paper Mill in Turkey. The physico-chemical treatability study was conducted by standard Jar-test equipment. The highest COD removal efficiency obtained was 96% for the paper machine, 50% for the alkali extraction and 20% for the bleaching effluents by using alum as coagulant. The colour removal efficiency was around 80% for the alkali extraction effluents. This study was cond...
Production and characterization of activated carbon from pistachio-nut shell
Özsin, Gamzenur; Yücel, Hayrettin; Behlülgil, Ahmet Kemal; Department of Chemical Engineering (2011)
In this study production and characterization of activated carbon from an agricultural waste, pistachio-nut shells, was investigated. To determine optimum production conditions by chemical activation method, effect of tempreature (300, 500, 700 and 900 oC) and effect of impregnation ratio (1:1, 2:1 and 3:1 as activation agent:sample) were investigated by applying two different methods (raw material activation and char activation) and with two different activation agents (phosphoric acid and potassium hydrox...
