Vol: 56(70) No: 1 / March 2011 Case Study for Control of Aerobic Industrial Wastewater Treatment Matei Vinatoru University of Craiova, Automation Department, Craiova, Romania, e-mail: vinatoru@automation.ucv.ro Keywords: Aerobic Industrial Wastewater Treatment Abstract The paper presents the possibility of automatic control of the biological wastewater treatment stations with applications in Romanian Chemical Companies. In this paper are developed a mathematical model for biological aeration basins and two automatic control systems (conventional control structure using three-positional controllers or PLC and advanced control structure using state estimators) for wastewater industrial purification.
