The activated sludge models (ASM) group has been created by IWA task group to facilitate a deep understanding of the activated sludge systems in wastewater treatment. The present study aims to assess validation of activated sludge model No. 2d (ASM2d) after being calibrated under conditions of the wastewater treatment plant (WWTP). The present study confirmed that applying the activated sludge model No. 2d (ASM2d) via computer-aided software is valid to describe the performance of WWTP in the current status, which suffers from the inadequacy of the treatment outputs to some extent with the standard specifications of reusing the treated wastewater for agricultural irrigation purposes. Furthermore, the calibrated ASM2d for conditions of the WWTP can be utilized to upgrade the integrated treatment system for enhancing the treatment quality in accordance with the permitted level of standard specifications of irrigation purposes.
