Enhanced post-denitrification without addition of an external carbon source in membrane bioreactors.
TLDR
It was shown that even without dosing of an external carbon source, denitrification rates much above endogenous rates could be obtained in post-denitrification systems, and the anaerobic reactor located ahead of the process had a positive impact on the DNR.About:

Membrane Bioreactors in Waste Water Treatment – Status and Trends
Matthias Kraume,Anja Drews +1 more
TL;DR: In this paper, the current status of membrane bioreactors and reports trends in MBR design and operation are given as well as guidelines for waste water treatment plant revamping, where specific or hybrid process configurations are shown to lead to, e.g., enhanced nutrient removal.
Journal ArticleDOI
The effect of dissolved oxygen concentration (DO) on oxygen diffusion and bacterial community structure in moving bed sequencing batch reactor (MBSBR).
TL;DR: Changing the DO concentration could alter the aerobic zone and the bacterial community structure in the biofilm, directly influencing the simultaneous nitrification and denitrification activity in MBSBRs.
Journal ArticleDOI
Advancing post-anoxic denitrification for biological nutrient removal
TL;DR: It is demonstrated that post-anoxic BNR can achieve near-complete (>99%) inorganic nitrogen and phosphorus removal, with soluble effluent concentrations less than 1.0 mgN L(-1) and 0.14 mgP L (-1).
Journal ArticleDOI
Post-anoxic denitrification driven by PHA and glycogen within enhanced biological phosphorus removal.
TL;DR: Success of the proposed process is predicated on providing sufficient organic acids in the influent wastewater, such that residual nitrate carried over from the post-anoxic period is reduced and polyhydroxyalkanoate (PHA) synthesis occurs.

Candidatus Accumulibacter phosphatis clades enriched under cyclic anaerobic and microaerobic conditions simultaneously use different electron acceptors.
Pamela Y. Camejo,Brian R. Owen,Joseph Martirano,Juan Ma,Vikram Kapoor,Jorge W. Santo Domingo,Katherine D. McMahon,Daniel R. Noguera +7 more
TL;DR: Results indicated that either organisms in this clade can simultaneously use multiple electron acceptors under micro-aerobic conditions, or that the use of multiple electrons by Clade IC is due to significant microdiversity within the Accumulibacter clades defined using the ppk1 gene.

Wastewater Engineering Treatment Disposal Reuse
TL;DR: Wastewater Engineering: An Overview of Wastewater Engineering, Methods and Implementation Considerations as mentioned in this paper is a good starting point for a discussion of the issues of wastewater engineering. But, it is not a complete survey of the entire literature.
Journal ArticleDOI
Microbiology and biochemistry of the enhanced biological phosphate removal process
TL;DR: In this paper, a review of the microbiological and biochemical aspects of the enhanced biological phosphate removal (EBPR) process is presented, including microorganisms responsible for EBPR, isolation of polyphosphate accumulating organisms (PAOs), microbial diversity of the EBPR sludge, biochemical metabolisms of PAOs, energy budget in PAOs metabolism, denitrification by PAO, glycogen accumulating non-poly-P organisms (GAOs), etc.
Journal ArticleDOI
Maintenance, endogeneous respiration, lysis, decay and predation
TL;DR: The processes grouped under endogenous respiration in activated sludge models, such as maintenance, lysis, internal and external decay, predation and death-regeneration are discussed and organised in order to create a working platform for discussing more detailed activatedSludge models.
Journal ArticleDOI
An integrated metabolic model for the aerobic and denitrifying biological phosphorus removal.
TL;DR: In this work, an integrated metabolic model for biological phosphorus removal is presented and a new kinetic structure is proposed that adequately describes phosphorus removal under denitrifying and aerobic conditions with the same kinetic equations and parameters.
