Start-up operation and hydraulic retention time selectivity for palm oil mill wastewater at mesophilic temperature in anaerobic suspended growth closed bioreactor
(Trans Tech Publications Inc., 2014)
The start-up operation and hydraulic retention time (HRT) selectivity of anaerobic degradation for palm oil mill effluent (POME) wastewater was carried out in an anaerobic bioreactor. HRT between 35 and 5 days were ...
Decolorization of methyl orange using upflow anaerobic sludge blanket (UASB) reactor-An investigation of co-substrate and dye degradation kinetics
(Taylor & Francis, 2013)
Decolorization of a synthetic wastewater containing Methyl Orange (MO) azo dye was performed in an upflow anaerobic sludge blanket (UASB) reactor. Color removal efficiencies approaching 94, 90 and 96% were obtained with ...
Evaluation of integrated anaerobic-aerobic biofilm reactor for degradation of azo dye methyl orange
(Elsevier Ltd., 2013-09)
This study was to investigate the mineralization of wastewater containing methyl orange (MO) in integrated anaerobic-aerobic biofilm reactor with coconut fiber as bio-material. Different aeration periods (3. h in phase 1 ...
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 ...
Heavy metal (iron) removal from landfill eachate by using two-stage constructed wetlands planted with Limnocharis flava and Eichhornia crassipes
(Universiti Malaysia Sarawak (UNIMAS), 2009-08-03)
The main purpose of this study was to treat heavy metal present in landfill leachate by the use of two-stage constructed wetland and planted with Limnocharis flava and Eichhornia crassipes. This study also examine the ...
Biological kinetics evaluation of anaerobic stabilization pond treatment of palm oil mill effluent
(Elsevier Ltd., 2009-11-21)
Biological kinetic (bio-kinetic) study of the anaerobic stabilization pond treatment of palm oil mill effluent (POME) was carried out in a laboratory anaerobic bench scale reactor (ABSR). The reactor was operated at different ...
Degradation of cationic and anionic dyes in coagulation-flocculation process using bi-functionalized silica hybrid with aluminum-ferric as auxiliary agent
(Royal Society of Chemistry, 2015)
Cationic dye (methylene blue) and anionic dye (methyl orange) degradation in the coagulation process was demonstrated. The key material was a natural coagulant-laterite soil dominated by a silica component, while aluminum-ferric ...
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 ...
Coagulation-flocculation of azo dye acid orange 7 with green refined laterite soil
(Elsevier B.V., 2014-06-15)
A novel degradation pathway of Acid Orange 7 (AO 7) by laterite soil in coagulation process is suggested. AO 7 has a strong azo bond links with benzene and naphthalene rings. The rings in AO 7 can be cleaved during coagulation ...
