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...

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...

Removal of E. coli with alternative media Biosand filters

Creator:: Fulton, Nathan J.
Abstract:: When Biosand filters cannot be constructed with crushed quarry rock due to resource limitations, a suitable alternative filter media is needed. In this research, two crushed quarry rock alternatives were examined. Three bench-scale Biosand filters with crushed rock, beach sand, and heat-treated beach sand media were simultaneously dosed with Willamette...

Examination of Immobilized TiO₂ Nanoparticle Photocatalytic Treatment of Stormwater by LilyPads

Creator:: Lopez, David A.
Abstract:: Stormwater runoff is a significant cause for impairment of many water bodies, a problem that will inevitably escalate due to increasing land-cover change associated with urbanization. The effect of stormwater runoff has spurred legislation and the subsequent development and adoption of Best Management Practices (BMPs) to treat stormwater. This work...

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...
