In Enhanced Biological Phosphorus Removal ( Ebpr ) Processes
Phosphorus is an essential element for every living organism, but when it exceeds certain limit in water bodies, it will cause serious environmental issues, such as eutrophication. P accumulation in water bodies can be caused by non-point sources, such as agriculture land runoff, as well as from point sources such as wastewater effluent discharges. In order to avoid eutrophication of water bodi...
متن کاملEffects of Solid Retention Time (SRT) on Sludge Characteristics in Enhanced Biological Phosphorus Removal (EBPR) Reactor
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 / = 8.3 d could achieve phosphate removal efficiency > 90 % and SVI < 100 mL g–1. In comparison, increasing SRT to / = 16.6 d led to a decrease of phosphate removal...
متن کاملMetabolic modelling of full-scale enhanced biological phosphorus removal sludge.
This study investigates, for the first time, the application of metabolic models incorporating polyphosphate accumulating organisms (PAOs) and glycogen accumulating organisms (GAOs) towards describing the biochemical transformations of full-scale enhanced biological phosphorus removal (EBPR) activated sludge from wastewater treatment plants (WWTPs). For this purpose, it was required to modify p...
متن کاملPolyphosphate kinase from activated sludge performing enhanced biological phosphorus removal.
A novel polyphosphate kinase (PPK) was retrieved from an uncultivated organism in activated sludge carrying out enhanced biological phosphorus removal (EBPR). Acetate-fed laboratory-scale sequencing batch reactors were used to maintain sludge with a high phosphorus content (approximately 11% of the biomass). PCR-based clone libraries of small subunit rRNA genes and fluorescent in situ hybridiza...
متن کاملHeterogeneity of intracellular polymer storage states in enhanced biological phosphorus removal (EBPR)--observation and modeling.
A number of agent-based models (ABMs) for biological wastewater treatment processes have been developed, but their skill in predicting heterogeneity of intracellular storage states has not been tested against observations due to the lack of analytical methods for measuring single-cell intracellular properties. Further, several mechanisms can produce and maintain heterogeneity (e.g., different h...
