The Development of a Calibration Methodology for a Realistic Primary Settling Tank (PST) Model
Published 2023“…However, previous models that replicated primary sedimentation units assumed that all the total settleable solids (TSS) components settled at the same velocities, which resulted in poor predictions of primary sludge characteristics and subsequently poor AD model predictions (with the PST underflow linked to AD in plant-wide settings). …”
