The most important purpose of wastewater treatment is to reduce pollution of the raw water and reclaim wastewater for reuse. Modeling and optimization of wastewater treatment processes were applied in this study to improve the efficiency of a wastewater treatment model. The model was applied on wastewater characterized by high organic loading and suspended solids concentrations. The approach was applied to optimize a treatment process of a two-step sequencing batch reactors SBR model. Also in this research we investigated the rule of denitrification process via anoxic conditions to remove nitrogenous compounds. Based on the results, it shows that two-step SBR model operates with removal efficiencies higher than 96% for biological oxygen demand (BOD), total suspended solids (TSS) and total kjeldahl nitrogen (TKN) were established. This modeling analysis applied to define a performance measuring plan based on the most important parameters that can be reliable and applicable for any waste water treatment plant.
