Using the activated sludge model 2d (ASM2d) to understand and predict the phosphorus accumulating organisms mechanism in enhanced biological phosphorus removal in relation to disintegrated sludge as a carbon source [PDF]
, 2012 Carbon sources are considered as one of the most important factors in the performance of enhanced biological phosphorus removal (EBPR). Disintegrated sludge (DS) can act as carbon source to increase the efficiency of EBPR.

Effects of Solid Retention Time (SRT) on Sludge Characteristics in Enhanced Biological Phosphorus Removal (EBPR) Reactor [PDF]
Chemical and Biochemical Engineering Quarterly, 2008 This study investigated the effects of solid retention time (SRT) on sludge characteristics and operational performance in enhanced biological phosphorus removal (EBPR) reactor. The results showed that the reactor operated at SRT of τ = 8.3 d could achieve phosphate removal efficiency η > 90 % and SVI < 100 mL g–1.

Phosphorus recovery from hydrothermal carbonization of organic waste: a review
Journal of Chemical Technology &Biotechnology, Volume 98, Issue 10, Page 2365-2377, October 2023., 2023 Abstract Background This review sheds light on the topic of phosphorus (P) recovery from hydrothermal carbonization (HTC) of organic waste. The paper focuses on the rising need for securing alternative P sources for the increasing demand, in addition to the development of HTC as a thermochemical technique for waste valorization.

Water Environment Research, Volume 95, Issue 8, August 2023., 2023 In this case‐study, aerobic granular sludge at full‐scale was more compact and still had lower energy usage than the conventional activated sludge, operated in parallel. However, both processes had the potential for decreased energy usage. Both processes produced low average effluent concentrations by biological nitrogen‐ and phosphorus removal ...

(Poly)phosphate biotechnology: Envisaged contributions to a sustainable P future
Microbial Biotechnology, Volume 16, Issue 8, Page 1616-1622, August 2023., 2023 The overall challenge of establishing a sustainable anthropogenic phosphate cycle did not change in the last decade, rather the need to act becomes ever more urgent. Here, I briefly highlight some developments in (poly)phosphate research within the last 10 years and dare a crystal ball look for topics that might help us towards a sustainable P society.

Water Environment Research, Volume 95, Issue 7, July 2023., 2023 The growth of polyphosphate accumulating organisms (PAOs) requires volatile fatty acids (VFAs) that are generated in the sludge blanket of the secondary clarifiers, offering a greater quantity of anaerobic biomass than the anaerobic zones in the bioreactor. Additionally, there are possibilities for enhancing the effectiveness of bio‐P in current system.
