Estimating (combinations of) Activated Sludge Model No. 1 parameters and components by respirometry

The paper presents a concise overview of respirometric experiments for the calibration of ASM1. First, the popularity of respirometry is explained by its historical impact and its sensitivity and robustness. The body of the t ext consists of a systematic overview of existing methods for assessment of nearly all ASM1: (i) component concentrations in sludge and waste water; a nd (ii) biokinetic and stoichiometric parameters. Real-life examples illust rate the methods. A difference is made between direct methods that use expl icit calculations and optimisation methods that require numerical optimisat ion algorithms. It is stressed that the latter approach is especially usefu l to extract multiple parameters and component concentrations from single r espirometric experiments. Finally, the importance of reflecting on the tran slation of lab-scale respirometric results to a full-scale model is stresse d. (C) 1999 IAWQ Published by Elsevier Science Ltd. All rights reserved.
