Biodegradation of azo dye Orange II using a granular activated carbon (GAC)-biofilm configured biological treatment systems
Ong, Soon-An; Toorisaka, Eiichi; Hirata, Makoto; Hano, Tadashi (Universiti Teknologi Mara (UiTM), 2006-12-08)Dyeing industry effluents constitute one of the most problematic wastewaters to be treated not only for their high chemical and biological oxygen demands, suspended solids and content in toxic compounds but also for color, ... -
Degradation of synthetic dye wastewater by using combined anaerobic-aerobic and aerobic sequencing batch reactors
Murali, V.; Ong, Soon-An; Nasrul, Hamidin, Dr.; Wong, Yee Shian; Ho, Li Ngee; Khairul Anuar, Pakri (Universiti Malaysia Perlis (UniMAP), 2012-06-18)Azo dyes are the dye used by the majority of the textile industries. The treatment options for this azo dye are physical, chemical and biological methods. The aim of this study was to assess the performance of dye ... -
Influence of chromium and powdered activated carbon (PAC) on activated sludge microorganisms and sequencing batch reactor treatment process
Ong, Soon-An; Toorisaka, Eiichi; Hirata, Makoto; Hano, Tadashi (Universiti Teknologi Mara (UiTM), 2006-12-08)One of the possibilities of using activated carbon in wastewater treatment is the direct addition of powdered activated carbon (PAC) to an activated sludge system, thus combining adsorption and biodegradation. The aim of ...
