Chemical transformation occurring (A) in a lab-scale batch experiment conducted with activated sludge collected on the 25th July 2013 and (B) at Ulu Pandan South Works on the 25th July 2013. Dashed line indicates a change of redox conditions from, in (A), anaerobic to aerobic conditions, and in (B), anoxic to aerobic conditions. Anoxic condition indicates the presence of nitrate, but not oxygen, as an electron acceptor.
