Treatment of azo dye Orange II in aerobic and anaerobic-SBR systems
(Elsevier, 2005-07)
The performance of aerobic- and anaerobic-SBR in treating Orange II-containing wastewater was investigated. The result from a specific oxygen uptake rate (SOUR) study showed that the Orange II compound did not exert ...
Effects of Cu(II) and Cd(II) on the performance of sequencing batch reactor treatment system
(Elsevier B.V., 2005-01)
The effects of Cu(II) and Cd(II)-containing wastewater on activated sludge microorganisms were investigated. The addition of Cu(II) and Cd(II) affected significantly the activities of activated sludge microorganisms in the ...
Effects of adsorbents and copper(II) on activated sludge microorganisms and sequencing batch reactor treatment process
(Elsevier B.V., 2003-10-31)
Wastewater treatment systems employing simultaneous adsorption and biodegradation processes have proven to be effective in treating toxic pollutants present in industrial wastewater. The objective of this study is to ...
Heavy metals and adsorbents effects on activated sludge microorganisms
(Wiley-VCH Verlag, 2004-01)
The sorption of Cu(II) and Cd(II) from synthetic solution by powdered activated carbon (PAC), biomass, rice husk (RH) and activated rice husk (ARH) were investigate under batch conditions. After activated by concentrated ...
Studies on adsorption and biodegradation of chromiumcontaining wastewater by laboratory-scale sequencing batch reactor-powdered activated carbon system
(Gh. Asachi Technical University of IASI, 2011-10)
The study involved investigating the effects of Cr(III) and the efficacy of powdered activated carbon (PAC) in reducing the inhibitory effects of Cr(III) on activated sludge under sequencing batch reactor (SBR) operation. ...
Biodegradation of redox dye Methylene Blue by up-flow anaerobic sludge blanket reactor
(Elsevier B.V., 2005-09-30)
The objective of this study is to evaluate the decolorization of Methylene Blue (MB) by an up-flow anaerobic sludge blanket (UASB) reactor. The UASB reactor was operated under batch condition with total treatment volume ...
Treatment of azo dye Orange II in a sequential anaerobic and aerobic-sequencing batch ractor system
(Springer Verlag, 2005-04)
We studied the biodegradation of Orange II in a sequential anaerobic and aerobic-sequencing batch reactor system. Granular activated carbon was used either packed into a column or added directly into the anaerobic reactor ...
Simultaneous removal of color, organic compounds and nutrients in azo dye-containing wastewater using up-flow constructed wetland
(Elsevier B.V., 2009-06-15)
Combination of aerobic and anaerobic processes in constructed wetlands can enhance the treatment performance in textile wastewater. This study assessed the treatment of azo dye Acid Orange 7 (AO7) and nutrients using five ...
Simultaneous adsorption and biodegradation processes in sequencing batch reactor (SBR) for treating copper and cadmium-containing wastewater
(Elsevier Limited, 2002)
The application of simultaneous adsorption and biodegradation processes in the same reactor is known to be effective in the removal of both biodegradable and non-biodegradable contaminants in various kinds of wastewater. ...
The behavior of Ni(II), Cr(III), and Zn(II) in biological wastewater treatment process
(John Wiley and Sons Ltd, 2005-06)
The purpose of this research was to investigate the effects of Ni(II), Cr(III), and Zn(II) on the treatment performance of sequencing batch reactor (SBR) system. The kinetics of adsorption study showed that the pseudo ...
