The total COD concentrations of influent DWW and CWW/SWW were 413.6±80.8 mg/L and 454.9 ± 51.3 mg/L, respectively. The UCBR was able to achieve average total COD removal efficiencies of 70 ± 10% and 80 ± 4% for DWW and SWW respectively. The total COD concentrations of the effluent of DWW and CWW/SWW were 122.5 ± 44.4 mg/L and 89.7 ± 10.3 mg/L, respectively. These observations suggested that heterotrophs in the UCBR system were able to better assimilate and remove carbon of mono-type SWW compared to diverse carbon sources such as DWW; although the influent soluble COD concentrations of the SWW were higher than those of the DWW. However, the effluent NH 4 +-N concentrations for both types of wastewater were rather similar,||Source Title:||Water Science and Technology||URI:||http://scholarbank.nus.edu.sg/handle/10635/91131||ISSN:||02731223||DOI:||10.2166/wst.2012.877|
