Background and Objectives: Advanced Sequencing batch reactors (SBR) are one of the most suitable modified activated sludge systems. Due to low cost, optimal efficiency, and easy operation, they are recognized as an effective biological treatment system. The purpose of this study was to determine the performance of the SBR biological process in the removal of organic matter and nutrients from Yazd city wastewater.
Materials and Methods: This descriptive study examines the trend of organic matter and nutrients changes in the biological process of advanced SBR. In this study, the samples were taken from the input and output of the SBR process four times a month for 9 months in 2019. A total of 72 samples were taken. Then COD (chemical oxygen demand) and BOD
5 (biochemical oxygen demand) and nutrients (phosphate (
