Abstract

Wastewater characterization constitutes the starting point before undertakings the designing process for wastewater treatment. Basically, wastewaters are contributed from various resources such as commercial, industrial and domestic. In this study, the municipal wastewater has been characterized in term of strength and treatability using 5-days Biochemical Oxygen Demand (BOD5) and Chemical Oxygen Demand (COD). But, these two conventional methods are becoming to be questioned as their relevance in representing microbial processes in wastewater. Oxygen Utilization Rate (OUR) is now being promoted as an alternative tool to characterize the wastewater. This study apply the OUR method to characterized municipal wastewater into various COD fractions. Seventeen (17) samples had been tested during laboratory work. Result from BOD5 and COD measurement gives that the municipal wastewater at sampling area are considered weak in strength and highly treatable. While, the result on OUR measurement and COD fraction analysis on municipal wastewater at sampling location show that the range of COD fractions of municipal wastewater in Malaysia differs from values reported by IAWPRC Task Group (Henze et al., 1987). The easily biodegradable COD, Ss, fraction in this study was found lower at manhole and (WWTP). The hydrolysable component was found higher for both locations compared to IAWPRC values. An equation has been established to find a relationship between BOD5 and Modified COD fractions. From the equation established, only a proportion (in percentage) of slowly biodegradable COD, XS2 are used in BOD5 process.
