The aim of this study was to evaluate the effectiveness application of sequencing batch
reactors (SBRs) for phosphorus removal compared to the conventional activated sludge (CAS)
treatment system. The results showed that the removal efficiency of phosphorus reached about
99% at wastewater treatment plant with CAS system. At the same time, the maximum phosphorus
removal efficiency can be achieved to 88% if the SBRs system operating parameters are
optimized. Finally, this study demonstrated that even if granules are not fully developed, the SBR
system is working with a good efficiency
