Comparative study on sequential batch reactor and granular sequencing batch reactor

Aerobic granular sludge technology can be one of the solutions to extend wastewater treatment plant when a limited space is available, besides Sequential Batch Reactor or biofilm carrier media technologies. This paper presents a comparative study between two types of technologies, Sequential Batch Reactor (SBR) and Granular Sequencing Batch Reactor (GSBR), using BioWin simulations based on the designed data of a wastewater treatment plant. Efficiencies of both technologies are studied regarding organic load and nutrients.
