Cultivation and Properties of Aerobic Granular Sludge

Aerobic granular sludge is the self immobilized sludge, which is recently found under the aerobic condition. Aerobic granular sludge demonstrates high settling velocities leading to good solid liquid separation, high biomass retention, high activity and an ability to withstand high loading rates. Granulation is a multiple phase process, which is depending on the composition of the substrate, the operation condition and selective pressure. Sequencing batch reactor is advantageous for the formation of aerobic granular sludge. This paper presents the aerobic sludge granulation, including the general properties, microbial morphology, the main conditions of granulation, the generation process and the aerobic granular sludge reactor.
