Continuity-based interfacing of models for wastewater systems described by Petersen matrices

Vanrolleghem, P A; Rosén, Christian LU ; Zaher, U; Copp, J; Benedetti, L; Ayesa, E and Jeppsson, Ulf LU (2005) In Water Science and Technology 52(1-2). p.493-500
Abstract
In this paper the Petersen and composition matrices that modellers are now familiar with are used as a basis to construct interfacing models between subsystems considered in wastewater treatment. Starting from continuity considerations and a set of transformation reactions between components used in the two models of the subsystems to be interfaced, a set of linear algebraic equations needs to be solved. The theoretical development is illustrated using a simplified integrated model of an activated sludge system coupled to an anaerobic digester. Continuity-guaranteed interfacing of subsystems will facilitate optimization studies of the within-the-fence process units of a wastewater treatment plant or of the integrated urban wastewater...
