(Pergamon-Elsevier Science Ltd, 2004)In this paper, a comparison of various advanced oxidation processes (O-3, O-3/UV, H2O2/UV, O-3/H2O2/UV, Fe2+/H2O2) and chemical treatment methods using Al-2(SO4)(3)(.)18H(2)O, FeCl3 and FeSO4 for the chemical oxygen demand ... -
Upgrading an existing treatment system to adopt cleaner production principals
(Elsevier Science Bv, 2004)In 1981, SEKA Cellulose and Paper Co. started pulp and newsprint paper production in Balikesir, Turkey. Production technology that was initially TMP (Thermo Mechanical Pulping) was converted to CTMP (Chemical Thermo ... -
Comparative evaluation of a laboratory and full-scale treatment alternatives for the vegetable oil refining industry wastewater (VORW)
(Elsevier Science Bv, 2004)The efficiency of alternative treatment processes in producing a final effluent conforming to regulatory standards with regards to chemical oxygen demand (COD) and oil and grease (O&G) loads was assessed. The study was ... -
A semi-empirical model for adsorption of magnesium ion from magnesium impurity-containing saturated boric acid solutions on Amberlite IR-120 resin
(Parlar Scientific Publications (P S P), 2007)In this study, the use of Amberlite IR-120, strong acidic cation exchange resin, was investigated to remove magnesium impurity from saturated boric acid solutions. The magnesium impurity caused by magnesium compounds in ... -
Prediction of SO2 and PM concentrations in a coastal mining area (Zonguldak, Turkey) using an artificial neural network
(Hard, 2007)In this study, artificial neural networks are proposed to predict the concentrations of SO, and PM at two different stations in Zonguldak city, a major coastal mining area in Turkey. The established artificial neural network ... -
Influence of draft tube cross-sectional geometry on K(L)a and epsilon in jet loop bioreactors (JLB)
(Elsevier Science Sa, 2007)Due to their compactness, and high flexibility in operation, the new processes like jet loop bioreactors (JLB) show a large potential for high removal efficiency and significant cost reduction in particular for the biological ... -
