About this document

Lars Rundqwist: Self-Tuning Control of The Dissolved Oxygen Concentration in An Activated Sludge System (1986) by Carlos Araújo Queiroz is a document available to read on EtoBox.

This thesis presents a self-tuning control system for managing dissolved oxygen concentration in an activated sludge aerator, implemented at Kappala Sewage Works in Sweden. The system achieved a standard deviation of 0.02 mg/l for DO concentration, significantly improving control accuracy and reducing air flow demand compared to manual methods. The results indicate potential economic benefits through decreased energy consumption and enhanced sludge settleability.
