Uppsala Dissertations from the Faculty of Science and Technology 64. 156 pp. Uppsala, Sweden. ISBN 91-5546311-8. More stringent requirements on nitrogen removal from wastewater are the motivation for this thesis. In order to improve treatment results and enhance co...
متن کاملHierarchical dissolved oxygen control for activated sludge processes
A hierarchical controller for tracking the dissolved oxygen (DO) reference trajectory in activated sludge processes is proposed and investigated. The removal of nitrogen and phosphorous from wastewater is considered. Typically, an aeration system itself is a complicated hybrid nonlinear dynamical system with faster dynamics compared to the internal dynamics of the DO in a biological reactor. It...
متن کاملTwo - Level Dissolved Oxygen Control for Activated Sludge Processes
Two-level controllers for dissolved oxygen reference trajectory tracking for activated sludge processes is proposed and investigated. Both the nutrient and the phosphorous removal from a wastewater by its biological treatment using an activated sludge technology are considered. Typically, an aeration system itself is a complicated hybrid nonlinear dynamical system with faster dynamics compared ...
متن کاملPrevalence of antibiotic resistant genes in selected activated sludge processes in Isfahan Province, Iran
Wastewater treatment plants are one of the main sources of dissemination of antibiotic resistance genes (ARGs) into the environment. The present study was conducted to determine the prevalence and removal of ARGs in different wastewater treatment processes. A total of 36 samples from raw and final effluent of different activated sludge processes were collected and analyzed. Molecular analysis w...
متن کاملComparison Study between Integrated Fixed Film Activated Sludge (ifas), Membrane Bioreactor (mbr) and Conventional Activated Sludge (as) Processes
Comparison study is required to evaluate the treatment efficiency of three alternative secondary treatment processes. These Processes are Integrated Fixed-film Activated Sludge (IFAS), Membrane Bioreactor (MBR) and Conventional Activated Sludge (AS). This study is required for a new wastewater treatment plant. The characteristics of the influent domestic wastewater for the proposed plant were m...
