The development of simultaneous partial nitrification, ANAMMOX and denitrification (SNAD) process in a single reactor for nitrogen removal.
Bacteria were found to exist in a dynamic equilibrium to achieve simultaneous nitrogen and COD removal in NRBC system and were mainly distributed in the aerobic outer part of the biofilm. Expand
In Situ Measurements of Denitrification in Constructed Wetlands
Quantitative estimates of denitrification are needed in designing artificial wetlands to optimize nitrate (NO 3 - ) removal. Acetylene blockage and 15 N-tracer methods were employed to quantifyExpand
Application of anaerobic ammonium-oxidizing consortium to achieve completely autotrophic ammonium and sulfate removal.
Denaturing gradient gel electrophoresis (DGGE) analysis revealed that a new organism belonging to Planctomycetales was strongly enriched in the defined niche: the redox of ammonium and sulfate. Expand
Control of COD/N ratio for nutrient removal in a modified membrane bioreactor (MBR) treating high strength wastewater.
Results showed that above 95.0% removal efficiencies of organic matter were achieved; indicating COD removal was irrespective of COD/N ratio. Expand
Simultaneous nitrification and denitrification coupled with phosphorus removal in an modified anoxic/oxic-membrane bioreactor (A/O-MBR).
Abstract In this study, simultaneous carbon, nitrogen and phosphorus (PO 4 3− -P) removals using an anoxic/oxic-membrane bioreactor (A/O-MBR) system without any circulation was investigated. TheExpand
Evaluation of oxygen adaptation and identification of functional bacteria composition for anammox consortium in non-woven biological rotating contactor.
Two strains similar to Nitrosomonas eutropha were responsible for oxygen consumption, which were able to exist in the autotrophic anaerobic condition for long periods and protect anammox bacteria Planctomycetales from the influence of oxygen. Expand
Catalytic co-pyrolysis of biomass and polyethylene in a tandem micropyrolyzer
Abstract In the present study, catalytic fast co-pyrolysis of biomass and polyethylene (PE) was studied in a tandem micro-pyrolyzer using HZSM-5 as the catalyst. Cellulose, xylan and milled woodExpand
The influence of controlling factors on the start-up and operation for partial nitrification in membrane bioreactor.
The results of reactor experiments showed that the free ammonia (FA) concentration of 74 mg NH(3)/L, as the influent ammonium concentration of 600 mg N/L, was a useful and effective factor to recover the partial nitrification performance. Expand
Kinetics and Modeling of Dissolved Phosphorus Export from a Tile‐Drained Agricultural Watershed
Agricultural runoff can be a source of P, a limiting factor for freshwater eutrophication. To develop a simple method to estimate P export from the cropland, we studied 1.2-μm filtered dissolvedExpand
Control of Microbial Sulfide Production with Biocides and Nitrate in Oil Reservoir Simulating Bioreactors
Up-flow sand-packed bioreactors injected with 2 mM sulfate and volatile fatty acids gave synergistic souring control with BAC and Glut, as indicated by increased RTs in the presence, as compared to the absence of nitrate. Expand
