Enhanced photocatalytic activity of fish scale loaded TiO 2 composites under solar light irradiation
(Elsevier B.V., 2012-06)
Fish scale (FS) loaded TiO2 composites were investigated as photocatalysts in degradation of Methyl Orange under solar light irradiation. Composites were prepared through sol-gel method by varying mass ratio of TiO2/FS at ...
Adsorption behavior of cationic and anionic dyes onto acid treated coconut coir
(Taylor and Francis Group, LLC., 2013-09)
The adsorption of Methylene Blue (MB) and Acid Orange 7 (AO7) from aqueous solutions by acid treated coconut coir was investigated under laboratory conditions to assess its potential in removing cationic and anionic dyes. ...
Mineralization of Methyl Orange-containing wastewater by integrated anaerobic and aerobic processes using spent granular activated carbon-biofilm under sequencing batch reactor operation
(Taylor & Francis, 2013)
Mineralization of azo dye required combination of anaerobic and aerobic processes either in two stages or single stage of treatment. The aim of the present study was to evaluate the treatment performance in the decolorization ...
Treatment of azo dye Acid Orange 7 containing wastewater using up-flow constructed wetland with and without supplementary aeration
(Elsevier Ltd., 2010-12)
The aim of this study is to examine and compare the treatment performance of Acid
Orange 7 (AO7) containing wastewater by up-flow constructed wetland (UFCW) at
different AO7 concentrations, hydraulic retention times (HRT) ...
Performance evaluation of laboratory scale up-flow constructed wetlands with different designs and emergent plants.
(Elsevier Ltd, 2010-10)
The objective of present study was to assess the simultaneous removal of organic pollutants and nutrients by five laboratory scale up-flow constructed wetlands (UFCWs). Aerobic and anaerobic regions were well developed at ...
Adsorption and toxicity of heavy metals on activated sludge
(Science Society of Thailand, 2010-09)
The adsorption of Cu, Cd, Ni, Zn, and Cr from synthetic solutions on powdered activated carbon (PAC),
activated sludge, and dried sludge were investigated under laboratory conditions to assess its ability to remove heavy ...
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. ...
Adsorption efficiency of garcinia mangostana linn. (GML) shells based activated carbon
(Trans Tech Publications, 2013)
The objective of this study is to investigate the adsorption efficiency of Garcinia Mangostana Linn. (GML) shells based activated carbon using two synthetic dyes which are methylene blue and acid orange 7. The parameters ...
Synergistic effect of up-flow constructed wetland and microbial fuel cell for simultaneous wastewater treatment and energy recovery
(Elsevier, 2016-03-01)
This study demonstrated a successful operation of up-flow constructed wetland-microbial fuel cell (UFCW-MFC) in wastewater treatment and energy recovery. The goals of this study were to investigate the effect of circuit ...
