Nitrogen Removal at Baltimore's Back River WWTP

Water Quality and Hydrologic Characteristics of a Wet Detention Pond
A small wet detention pond was instrumented to determine treatment efficiencies. Annual loads showed a reduction from the inflow to the outflow for ammonia as nitrogen (39%), organic nitrogen...

Transportation Planning and Air Quality
This proceedings, Transportation Planning and Air Quality, consists of papers presented at the National Conference sponsored by the Urban Transportation...

Effect of Ionizing Radiation on the Waste Package Environment
The radiolytic production of nitrogen oxides, nitrogen acids and ammonia are discussed in relation to the expected environment in a high-level waste repository that may be constructed...

Eutrophication and its Effects on Coastal Habitats

Controlling Nitrogen Loading to Coastal Waters
Of the countless contaminants that reach coastal waters, nitrogen is one of the most problematic and least regulated. There is ample evidence that many coastal embayments are overwhelmed...

Combined Nitrogen and Phosphorus Removal in a Cyclic Activated Sludge System Without Anoxic Mixing Sequences
A simplified methodology for combined phosphorus and nitrogen removal through reactor configuration, cyclic sequencing and the control of aeration intensity in variable volume activated...

Anoxic-Aerobic Activated Sludge Treatment
An activated sludge system was operated at a relatively low SRT of 1-2 days at the City of Phoenix to meet secondary treatment requirements. Operating MLSS concentrations were 400-600...

Impact of Nitrogen and Water Management on Ground Water Quality
Nitrate-nitrogen (NO3-N) concentrations in shallow ground water of the Platte River Valley in Central Nebraska have been increasing since the 1950s...

Modeling Nitrogen Movement Through Loess Soils
This study evaluates the ability of the Root Zone Water Quality Model (RZWQM) to track the movement and fate of nitrate (NO3--N)...

Isotropic Fractionation During Air-Water Transfer of Oxygen and Nitrogen
We present empirical results that show the kinetic fractionation during gas exchange is 0.9972 ± .0002 for oxygen and 0.9987 ± .0001 for nitrogen. These values are larger than the solubility...
