Abstract

The measurement of biomass concentration is important in biological wastewater treatment. This paper compares the accuracy and costs of the traditional volatile suspended solids (VSS) and the proposed suspended organic carbon (SOC) methods. VSS and SOC values of a dilution system were very well correlated (R² = 0.9995). VSS and SOC of 16 samples were determined, the mean SOC/VSS ratio (0.52,n = 16, o = 001, ) was close to the theoretical value (0.53). For costing analysis, two hypothetical cases were analysed. In case A, it is assumed that 108 samples are analysed annually from two continuous reactors. Case B represents a batch experiment to be carried out in 24 incubated serum bottles. The savings, when using the SOC method, were £11987 for case A and £90 for case B. This study suggests the use of SOC method as a time saving and lower cost biomass concentration measurement.
