The SBR systems were operated with Fill, React, Settle, Draw and Idle periods in the time ratio of 0.5 : 3.5 : 1.0 : 0.75 : 0.25for a cycle time of 6 hours. It was observed that the addition Cu(II), Cd(II) and combined Cu(II) and Cd(II)-containing wastewater into SBR A, B and C, respectively, had caused deterioration in bio-oxidation processes carried out by activated sludge microbes. From SOUR study, Cu(II) exhibited more toxic to the activated sludge microbes compared to Cd(II). 2010-01-01T03:53:40Z 2010-01-01T03:53:40Z 2007 Article Journal of Engineering Research and Education, vol. 4, 2007, pages 20-24. 1823-2981 http://www.unimap.edu.my/ http://hdl.handle.net/123456789/7445 en Universiti Malaysia Perils |
