ABSTRACT
Aerobic granulation can be observed as the future for industrial, municipal /or mixed wastewater treatment systems. Advanced sequencing batch reactor (SBR) technologies consist of pre-anoxic selectors that are perceived to help make larger sludge flocs (characterized to work as aerobic sludge granulation) by suppressing filamentous bacteria and governing simultaneous nitrification and denitrification by controlled aeration sequences. The 3-MLD capacity SBR in Roorkee, India, was analyzed in the study for sludge granulation (denser and stronger microbial structure formation). The sludge granulation mechanism removes carbon, nitrogen, phosphorus as well as other pollutants from a single bioreactor under the same operational conditions. There are several processes like aerobic sludge granulation- continuous flow reactor (AGS-CFR), aerobic sludge granulation- membrane bioreactor (AGS-MBR), and SBR systems which performed for aerobic sludge granulation. After varying the operational provisions of SBR, a municipal wastewater treatment plant can be developed from activated sludge to aerobic granular sludge technology.
