Alternative Title: Parameter Estimation of Anoxic-Oxic-Anoxic-Stripper Process and Design of Reactor Volume using Response Surface Methodology

Abstract: Modelling of activated sludge processes has become a common part of the design and operation of wastewater treatment plants.
It is necessary to correct parameter values e.g. specific growth rate, half saturation constants etc of ASM1, ASM2, ASM3, presented by IWA Task Group to apply to the operation of domestic wastewater treatment plants.
Therefore, this thesis estimated adequate operating parameteric values of wastewater treatment plant in Busan by response surface analysis and optimized the retention time of each reactor of AOAS process to reduce pollution by mixture design.
Statistical programs used were Aqusim 2.1 & Minitab 14.
Results obtained were that estimated parametric values were bA 0.12/d, bH 0.26/d, bPAO 0.22/d, μA 1.17/d, μH 3.05/d, μPAO 1.00/d, qPP 1.19/d, repectively and the optimized proportion ratio of each reactor volume could be designed through the optimized proportion ratio of retention time of each reactor.
The designed proportion ratio of each reactor volume was 1.95(Anoxic1) : 5.22(Oxic1) : 1.44(Anoxic2) : 1.39(Oxic2).
