Biological nutrients eradication employing Aerobic Granulation
… an insight of an emerging biotechnology: Aerobic Granulation, for its suitability to remove phosphorus (growth limiting nutrient) and nitrogen existing in domestic wastewater. The research focuses on investigation of different mechanisms supporting domestic level phosphorus removal in …

Nutrient (Ammonium and Phosphate) Removal Using Aerobic Granulation at Pilot scale
This research investigated the causes of aerobic granulation inhibition and deterioration in nutrient removal performance of aerobic granular sludge (AGS) reactors at pilot scale. Identifying the underlying phenomena seems necessary to enhance predictability and reliability of this process under …

Advanced Biofilm and Aerobic Granulation Technologies for Water and Wastewater Treatment
… BNR techniques for stormwater nitrogen removal. Aerobic granules are an even more advanced attached growth process, which eliminates the need for abiotic carrying media. So far, aerobic granular sludge is only formed in sequential batch reactors but not in a continuous flow system. Therefore, …

Mechanistic Understanding of the NOB Suppression by Free Ammonia Inhibition in Continuous Flow Aerobic Granulation Bioreactors
… that a mixture of large anammox-supported aerobic granules (ASAGs) and small conventional aerobic granules (CAGs) can be maintained stably for extended periods of time. The influent NH4+ was kept at 50 - 60 mg N L-1 to verify that the upper range of total ammonia nitrogen (TAN) for domestic …

METABOLIC SHIFT AND NICHE DIFFERENTIATION DURING DENITRIFYING PHOSPHORUS REMOVAL IN A TROPICAL CLIMATE
… in EBPR processes under tropical conditions. Aerobic granulation and alternating carbon sources were used to obtain Accumulibacter enrichment at 30&176C. It was surmised that involvement of partial TCA-glycolysis cycle or complete glycolytic pathway in Accumulibacter affects phosphorus removal …

Carbon-efficient Wastewater Treatment Through Resource Recovery, Process Intensification, and Partial Denitrification Anammox
… process intensification through continuous-flow aerobic granulation was explored in plug flow reactors. The results demonstrated that MLR configuration could hinder the sludge granulation, but the hindrance could be alleviated to some extent by its location change. In order to eliminate the …

Rapid Startup of Aerobic Granular Sludge Using Cationic Polymer For Industrial Wastewater Treatment
… and recovery of resources from wastewater. An aerobic granular sludge sequencing batch reactor (AGS SBR) was developed to address the nutrient removal and solid-liquid separation challenges associated with the conventional activated sludge (AS) process. AGS technology tackled the primary …
-
Effect of Process Intensification Techniques on Biosolids Management
… treatment on biosolids management in terms of anaerobic digestion enhancement, dewaterability improvement, odor mitigation, as well as phosphorus and nitrogen removal. The first part of this study was conducted to understand the effect of anaerobic digester solids retention time (SRT) on odor …

Development of Transitional Settling Regimen Parameters to Characterize and Optimize Solids-liquid Separation Performance
… a sludge matrix. Furthermore, the emergence of aerobic granulation as a potential pathway to mitigate solid-separation issues further stresses the need for new settling characteristic metrics to enable integration of the new technology with the current infrastructure. The granule or intrinsic …

Mechanistic understanding of biogranulation for continuous flow wastewater treatment and organic waste valorization
Aerobic granular sludge has been regarded as a promising alternative to the conventional activated sludge which has been used for a century in that granular sludge offers advantages in high biomass retention, fast sludge-water separation, and small footprint requirement. However, this technology …
