Location and chemical composition of microbially induced phosphorus precipitates in anaerobic and aerobic granular sludge [PDF]

, 2012
This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core

Treatment of old landfill leachate with high ammonium content using aerobic granular sludge

Journal of Biological Engineering, 2017
Background Aerobic granular sludge has become an attractive alternative to the conventional activated sludge due to its high settling velocity, compact structure, and higher tolerance to toxic substances and adverse conditions.

Transport and retention of artificial and real wastewater particles inside a bed of settled aerobic granular sludge assessed applying magnetic resonance imaging

Water Research X, 2020
The removal or degradation of particulate organic matter is a crucial part in biological wastewater treatment. This is even more valid with respect to aerobic granular sludge and the impact of particulate organic matter on the formation and stability of ...

Tetracycline exposure shifted microbial communities and enriched antibiotic resistance genes in the aerobic granular sludge

Environment International, 2019
The aerobic granular sludge with larger size and more compact spherical structure generally shows excellent performance in antibiotic removal, yet little is known about the long-term effect of environmentally-relevant concentration (μg/L) of antibiotics ...

Is building up substrate during anaerobic feeding necessary for granulation?

Water Science and Technology, 2022
For a successful granulation process in activated sludge systems, the stimulation of slow growing organisms such as glycogen accumulating microorganisms (GAOs) is a key factor.

Settling behaviour of aerobic granular sludge

Water Science and Technology, 2007
Aerobic granular sludge (AGS) technology has been extensively studied recently to improve sludge settling and behaviour in activated sludge systems. The main advantage is that aerobic granular sludge (AGS) can settle very fast in a reactor or clarifier because AGS is compact and has strong structure.
