Nitrogen recovery from simulated sand-filter effluent by grass

Creator:: Hall, Thomas David
Abstract:: The effluent from on-site sewage disposal systems has been found to be a source of nitrates (NO ₃⁻ ) in groundwater. Vegetation has the ability to remove some of the nitrogen (N) from sewage effluent as the solution moves through the soil around a disposal trench, before it reaches groundwater....

Evaluating the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with carbon-containing solid substrates

Creator:: Hart, Jeffrey L.
Abstract:: The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...

Transport and transformations of nitrogen compounds in effluent from sand filter-septic system draintile fields

Creator:: Bushman, Jennifer L.
Abstract:: A total of 44 intermittent sand filter-septic systems, in five counties of Western Oregon, were sampled over a three-month period during the summer of 1995. The sand filter systems varied in age from 36 months up to 167 months (3 to 13.9 years). Liquid samples were taken from the septic...

Hydraulic characterization and modeling of the Talking Water Garden wetland for evaluation of nitrogen removal

Creator:: Huang, Tao
Abstract:: The purpose of this research is to hydraulically characterize an engineered wetland in Albany, Oregon. The wetland receives treated wastewater from both Albany Millersburg Water Reclamation Facility (AMWRF) and ATI Wah Chang. AMWRF's water is municipal waste water. ATI Wah Chang's water comes from its nearby metal processing plant. The...

An ammonia stripping and recovery system for animal wastewaters

Creator:: Crown, Julia K.
Abstract:: Traditionally, livestock operations were small and combined with cropping operations. This allowed farms to be self-sustaining because nutrients were constantly recycled on the farm. Since the Haber-Bosch chemical process was patented, crop farmers turn to industrial fertilizers when soils nutrients are depleted. Animal and plant operations diverged, functionally separated, and...

Molecular and Kinetic Characterization of Anammox Bacteria Enrichments and Determination of the Suitability of Anammox for Landfill Leachate Treatment

Creator:: Sultana, Sharmin
Abstract:: Anaerobic ammonium oxidation (anammox) has recently appeared as a promising approach for removing nitrogen from landfill leachates because it requires less oxygen and no organic carbon compared to traditional nitrification-denitrification system, and it produces low sludge volumes, thereby reducing operating and biological sludge disposal costs by over 60%. Anammox bacteria...

Preliminary study on the effect of pH on the treatment of lead contaminated wastewaters with ozone

Creator:: Adolf, Ronald L.
Abstract:: Ozone was found to quickly reduce the concentration of lead in a prepared solution when the solution pH of said solution was greater than 7.0. When a solution having a pH of greater than 7.0 was filtered the concentration of lead was less than approximately 1.0 ppm. 1.0 ppm is...

Potential of a fungus, Acremonium sp., to decolorize pulp mill effluent

Creator:: Lesley, Dawn
Abstract:: This project explored the feasibility of using fungi in a constructed wetland for the treatment of pulp mill effluent. The effluent is high in dissolved lignins (some of which are chlorinated), which have proven very difficult to degrade biologically. Mindful of work done with the (terrestrial) white rot fungi, especially...

Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:: Bartow, Shannon M.
Abstract:: The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...
