Abstract

BACKGROUND: Household wastewater was segregated to grey and black water components as part of a recent approach aiming to separate wastewater fractions for more efficient treatment and reuse. Chemical oxygen demand (COD) fractionation and biodegradation characteristics of black and grey water were determined by means of model calibration of the oxygen uptake rate profiles. An ASM1 type of model modified for endogenous respiration was selected for this purpose.
