Aerobic Granular Sludge In Sequencing Batch Reactor

ABSTRACT

Approximately 100 years old activated sludge technology is the primary method of wastewater treatment. Nowadays, end-users preferred to have compact wastewater treatment plants and the biofilm process is best suited for the same. In biofilm technology, conversion is limited by the surface area where the biofilm is attached. In granular biomass technology, maximum surface area per volume of the reactor can be obtained. Curiosity to understand and experience the aerobic granular sludge leads to the set-up of a pilot plant installed at Muscat. We explored whether granular sludge can be developed to treat domestic sewage under Sultanate of Oman's conditions. Our center of attention was to categorize the key operating parameters to support granular sludge formation.
