Adsorption and toxicity of heavy metals on activated sludge
Soon-An, Ong; Toorisaka, Eiichi; Hirata, Makoto; Hano, Tadashi (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 ... -
Combination of adsorption and biodegradation processes for textile effluent treatment using a granular activated carbon-bioflm confgured packed column system
Soon-An, Ong; Toorisaka, Eiichi; Hirata, Makoto; Hano, Tadashi (The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences, 2008)The objective of this study was to investigate the feasibility of using a granular activated carbon-biofilm configured packed column system in the decolorization of azo dye Acid Orange 7-containing wastewater. The Acid ... -
Granular activated carbon-biofilm configured sequencing batch reactor treatment of C.I. Acid Orange 7
Soon-An, Ong; Toorisaka, Eiichi; Hirata, Makoto; Hano, Tadashi (Elsevier Ltd, 2008)The aim of this study is to investigate the mineralization of C.I. Acid Orange 7 (AO7) by biological process in oxygen limited condition under GAC-biofilm configured sequencing batch reactor (SBCR) operation. The granular ... -
Performance evaluation of laboratory scale up-flow constructed wetlands with different designs and emergent plants.
Soon-An, Ong; Uchiyama, Katsuhiro; Inadama, Daisuke; Ishida, Yuji; Yamagiwa, Kazuaki (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 ... -
Treatment of azo dye Acid Orange 7 containing wastewater using up-flow constructed wetland with and without supplementary aeration
Soon-An, Ong; Uchiyama, Katsuhiro; Inadama, Daisuke; Ishida, Yuji; Yamagiwa, Kazuaki (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) ... -
Treatment of methylene blue-containing wastewater using microorganisms supported on granular activated carbon under packed column operation
Soon-An, Ong; Toorisaka, Eiichi; Hirata, Makoto; Hano, Tadashi (Springer-Verlag, 2007-05)We studied the feasibility of using biological granular activated carbon-packed column in treating methylene blue-containing wastewater. The granular activated carbon with immobilized microbes was packed into a column and ...
