Controlling Nitrogen in Coastal Waters
Excess nitrogen in coastal waters is becoming a problem worldwide. Nutrients such as nitrogen come from sewage treatment plants, septic tanks, runoff from fertilizer and animal waste,...
Water Quality Modelling: Prediction of the Transport of Water Constituents in the Weser Estuary (Germany)
Water quality monitoring of the Weser estuary is carried out in conjunction with numerical modelling of the transport processes. For analytical and prognostical studies, and especially...
Use of Groundwater Models to Simulate Remediation
Flux of Metals Between Sediment and the Water Column
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
Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...
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...
Effects of Temperature and Mean Cell Residence Time on Enhanced Biological Phosphorus Removal
The effects of temperature and mean cell residence time (MCRT) on biological phosphorus and nitrogen removal were investigated by operating pilot-scale continuous-flow activated sludge...
The Effect of Operational Parameters on the Acid-phase Anaerobic Fermentation in the Biological Phosphorus Removal Process
A series of laboratory-scale, continuous flow experiments has been employed to study the effects of selected HRTs and SRTs on the acid-phase fermentation of primary sludge. The VFA production...
Protecting a Sensitive Ecosystem Through Advanced Treatment at the Reno-Sparks Wastewater Treatment Facility
The requirements for high degrees of nutrient removal at the Reno-Sparks Wastewater Treatment Facility required employment of several cost-effective, innovative treatment process applications....
