Dynamiska modeller för reningsverk

Sammanfattning: The purpose of this report is to study dynamic models of processes used in waste water treatment. The report consists of a literature study and identification of two different unit processes.
The literature study consists of a thorough search of some relevant periodicals, and the result is presented as a collection of abstracts of articles, treating dynamic aspects of waste water treatment technology. A dynamic model of an activated sludge process is presented in detail.
Identification have been performed on data from an activated sludge process in Palo Alto, Calif. Chemical precipitation experiments followed by maximum likelihood identifications have also been performed for a unit och the Sjölunda Wastewater Treatment Plant, Malmö. Linear stochastic dynamic models of first and second order of the two processes are presented.
