2-fluorophenol degradation by aerobic granular sludge in a sequencing batch reactor.
Aerobic granular sludge is extremely promising for the treatment of effluents containing toxic compounds, and it can economically compete with conventional activated sludge systems. A laboratory scale granular sequencing batch reactor (SBR) was established and operated during 444 days for the treatment of an aqueous stream containing a toxic compound, 2-fluorophenol (2-FP), in successive phases...
متن کاملAerobic Sludge Granulation in a Full-Scale Sequencing Batch Reactor
Aerobic granulation of activated sludge was successfully achieved in a full-scale sequencing batch reactor (SBR) with 50,000 m(3) d(-1) for treating a town's wastewater. After operation for 337 days, in this full-scale SBR, aerobic granules with an average SVI30 of 47.1 mL g(-1), diameter of 0.5 mm, and settling velocity of 42 m h(-1) were obtained. Compared to an anaerobic/oxic plug flow (A/O)...
متن کاملSequencing Batch Reactor Operation for Treating Wastewater with Aerobic Granular Sludge
In this work, the performance of a sequencing batch reactor (SBR) on aerobic granular sludge was studied for urban wastewater treatment. The system was inoculated with aerobic activated sludge collected from a wastewater treatment plant and, after 30 days of operation, the first granules observed had an average diameter of 0.1 mm. The biomass concentration reached a maximum value around 4 g VSS...
متن کاملSequencing batch reactor (SBR) and sequencing batch airlift reactor (SBAR) with the formation of aerobic granules
This research examined novel configuration of SBAR in lab-scale for industrial wastewater treatment. To evaluate COD removal efficiency and granules formation of the novel reactor (R1), SBAR system (R2) was operated under similar conditions during the experimental period. R1 and R2 with working volume of 3.6 and 4.5 L were used to cultivate aerobic granules. Both reactors were operated for 4 hr...
متن کاملNitrogen Removal over Nitrite by Aeration Control in Aerobic Granular Sludge Sequencing Batch Reactors
This study investigated the potential of aeration control for the achievement of N-removal over nitrite with aerobic granular sludge in sequencing batch reactors. N-removal over nitrite requires less COD, which is particularly interesting if COD is the limiting parameter for nutrient removal. The nutrient removal performances for COD, N and P have been analyzed as well as the concentration of n...
