Sequencing Batch Reactors have been used in wastewater treatment for over a century and remain a reliable option for municipal and industrial applications. The paper explains how newer developments, especially Aerobic Granular Sludge and INVENT’s iSBR®/iGSR® technology, can improve the process. It focuses on practical challenges such as flow equalization, equipment sizing, scale-up, and mixing, and shows how the iC³ process addresses them.
