Advancements in the application of aerobic granular biomass technology for sustainable treatment of wastewater
TLDR
Aerobic granular sludge technology can be regarded as the future standard for industrial and municipal wastewater treatment as discussed by the authors, and a growing number of institutes and universities focus their scientific research on this new technology.Abstract:
Aerobic granular sludge technology can be regarded as the future standard for industrial and municipal wastewater treatment. As a consequence, a growing number of institutes and universities focus their scientific research on this new technology. Recently, after extensive Dutch research and development effort, an aerobic granular biomass technology has become available to the market. Full scale installations for both industrial and municipal applications are already on stream, under construction or in design. The technology is distinguished by the name ‘Nereda®’ and based on the specific characteristics of aerobic granular sludge. It can be considered as the first mature aerobic granular sludge technology applied at full scale. It improves on traditional activated sludge systems by a significantly lower use of energy and chemicals, its compactness and its favorable capital and operational costs.read more

Aerobic sludge granulation in a full-scale sequencing batch reactor.
TL;DR: X-ray fluorescence analysis revealed that metal ions and some inorganics from raw wastewater precipitated in sludge acted as core to enhance granulation, and the SBR mode operating with periodic feast-famine, shorter settling time, and no return sludge pump played a crucial role in aerobic sludge granulation.

Behavior of polymeric substrates in an aerobic granular sludge system.
TL;DR: Many protozoa and metazoans were observed in laboratory reactors as well as in pilot- and full-scale Nereda(®) reactors, indicating an important role in the removal of suspended solids too.
Aerobic granular sludge : Scaling up a new technology
TL;DR: In this paper, the authors describe the development of a new compact aerobic granular sludge technology, in which the biomass is grown in compact granular structures and the main advantage of this compact growth structure is the higher biomass concentrations that van be reached and that all processes, needed for the treatment of wastewater, can be performed in one (discontinuously operated) reactor.
