Production of bioflocculant by staphylococcus cohnii ssp. from Palm Oil Mill Effluent (POME)
Wong, Yee Shian; Ong, Soon An, Dr.; Teng, Tjoon Tow; Nabilah Aminah, Lutpi; Kumaran, Kasthuri (Springer Science+Business Media B.V., 2012-09)Staphylococcus cohnii ssp. was found to produce a bioflocculant with high flocculating activity for kaolin suspension. Using optimized culture conditions, a flocculating activity of 70.3 % at a bioflocculation concentration ... -
Solar photocatalytic degradation of mono azo methyl orange and diazo reactive green 19 in single and binary dye solutions: Adsorbability vs photodegradation rate
Ong, Soon An, Dr.; Ohm, Mar Min; Ho, Li Ngee, Dr.; Wong, Yee Shian (Springer-Verlag Berlin Heidelberg, 2013-05)The objective of this study was to examine the effects of adsorbability and number of sulfonate group on solar photocatalytic degradation of mono azo methyl orange (MO) and diazo Reactive Green 19 (RG19) in single and ... -

Nabilah Aminah, Lutpi; Nurul Najiha, Jamil; Che Ku Kairulazam, Che Ku Abdullah; Wong, Yee Shian; Ong, Soon An, Dr.; Tengku Nuraiti, Tengku Izhar (Trans Tech Publications, 2013)The adsorption of Methylene Blue (MB) and Acid Orange 7 (AO7) dye onto Ananas Comosus Mixed Peels and Leaves (ACMPL) were carried out by conducting four different parameters such as initial concentration, pH, dosage of ... -
Treatment of azo dye Orange II in a sequential anaerobic and aerobic-sequencing batch ractor system
Ong, Soon An; Eiichi, Toorisaka; Makoto, Hirata; Tadashi, Hano (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 ... -
Treatment of azo dye Orange II in aerobic and anaerobic-SBR systems
Ong, Soon An; Eiichi, Toorisaka; Makoto, Hirata; Tadashi, Hano (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 ...
