An investigation of heavy metal biosorption in relation to C/N ratio of activated sludge
Yuncu, Bilgen; Sanin, Faika Dilek; Yetiş, Ülkü (2006-09-21)
The effect of ON ratio of activated sludge on heavy metal biosorption was investigated. Three sets of semi-continuous reactors with different feed ON ratios (9, 21 and 43 mg COD/mg TKN) were set up. Sorption equilibrium tests have indicated that the biosorptive capacity of activated sludge was highly dependent on metal species and the ON ratio. The increase in ON ratio resulted in an increase in the Cd(II) sorption capacity of activated sludge whereas it decreased the Cu(II) sorption capacity. As for Zn(II)...
An investigation of the microstructural and mechanical properties of tri-calcium phosphates doped with aluminum and fluoride ions
Tahmasebifar, Aydin; Evis, Zafer; Department of Engineering Sciences (2011)
The aim of this study was to investigate the microstructure and mechanical properties of pure tricalcium phosphate (TCP) and tricalcium phosphates doped with aluminum (Al3+) and fluoride (F-) ions at different compositions. TCP was synthesized via precipitation method and sintered at 1100C for 1 and 5 h. It was observed that density and relative density of the sintered materials were decreased by extending the sintering time. Increased densities were achieved upon Al3+ and/or F- doping. For structural anal...
AN EXPERIMENTAL AND NUMERICAL STUDY OF BALLISTIC PERFORMANCE OF SFRC STRUCTURES
Aleessa Alam, Burhan; Toksoy, Kaan; Dara, Gokce; Göktepe, Serdar; Yaman, İsmail Özgür (2016-05-13)
This contribution is concerned with the experimental and numerical study of ballistic performance of steel fiber reinforced concrete structures. For this purpose, three different types of panels, made of steel fiber reinforced concrete (SFRC), slurry-infiltrated concrete (SIFCON), and ceramic composite (CC), have been tested under high velocity impact of a rigid projectile. Explicit Finite Element analyses aiming at capturing the experimental residual velocities for the SFRC and SIFCON panels have also been...
An investigation into the thermal behavior of coals
Kök, Mustafa Verşan (2002-10-01)
The thermal behavior of 4 coal samples was investigated using simultaneous thermogravimetry (TG/DTG) and differential thermal analysis (DTA) methods. Upon heating the coals in an inert atmosphere up to 800degreesC, 31.44-43.82% weight loss occurs. The 2 temperature regions of increased chemical reactivity are evident in the coal samples studied Two different models determined kinetic analysis of the samples, and the results are discussed.
