Based on Fig. 2f, it can be evidently seen that OLR substantially
influences the COD, BOD and TSS removal efficiency. The OLR and
SLR trend demonstrates similarity with the COD, BOD and TSS
removal trend as shown in Fig. 2a. It was observed that the SLR
follows the trend of OLR. In general, the percentage of COD, BOD
and TSS removed increased with increased OLR over the range of
1.2e2.4 kg COD/m3 day. This result denotes that a high OLR can
enhance the activity of aerobic microorganism and this shows
a good concordance with the results presented by Chen et al.
(2008). Hence, it implies that the SBR had yet to reach its
maximum operational limit and higher OLR should be applied in
order to achieve higher organic removal efficiency.
