Decolorization of methyl orange using upflow anaerobic sludge blanket (UASB) reactor-An investigation of co-substrate and dye degradation kinetics
Viswanathan, Murali; Ong, Soon An, Dr.; Ho, Li Ngee, Dr.; Wong, Yee Shian (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
Viswanathan, Murali; Ong, Soon An, Dr.; Ho, Li Ngee, Dr.; Wong, Yee Shian (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 ... -
Mineralization of diazo dye (Reactive Black 5) in wastewater using recirculated up-flow constructed wetland reactor
Ong, Soon An, Dr.; Ho, Li Ngee, Dr.; Wong, Yee Shian; Chen, Siaw Fun; Viswanathan, Murali; Rohazita, Bahari (Desalination Publications, 2012)Application of a sequential anaerobic and aerobic process in a constructed wetland can enhance the treatment performance of textile wastewater. In this study, two laboratory-scale recirculated up-flow constructed wetland ... -
Photocatalytic mineralization of azo dye Acid Orange 7 under solar light irradiation
Ong, Soon An, Dr.; Ho, Li Ngee, Dr.; Wong, Yee Shian; Ohm, Mar Min; Lai, Li Sze; Khiew, Siee Kung; Viswanathan, Murali (Desalination Publications, 2012)The objective of this study was to investigate mineralization of hazardous water soluble azo dye Acid Orange 7 (AO7) under photocatalytic process. In this experiment, sunlight was used as the source for UV irradiation and ...
