Abstract

Nowadays, an activated sludge process is the most commonly used biological wastewater treatment process. In addition to its cost-effective properties in removing the organic material form wastewater, it is flexible, reliable, and has the capability of producing high quality effluent. Advanced models simulating the complex biochemical reactions taking place in activated sludge reactors have been progressively applied in many process fields. Examples of these models are the International Water Association Models (ASM) No.1, ASM No.2, and ASM No.3. A mathematical framework is developed for use in the optimal sizing of a wastewater treatment system comprising an activated sludge system preceded by a primary clarifier. Rec
