Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

The control and fate of enteric bacteria in the environment with particular emphasis on the factors influencing fecal indicator survival in waste storage facilities

Creator:: Crane, Stuart R.
Abstract:: The indiscriminate release of fecal bacteria to the environment can present a public health hazard when pathogenic species gain access to drinking and recreational water sources. The extent of bacterial contamination of surface and ground waters associated with animal production units and waste application areas seems largely dependent on the...

Flow characteristics of constructed wetlands : tracer studies of the hydraulic regime

Creator:: Stairs, Darrin B.
Abstract:: Treatment efficiency in a constructed wetland is related in part to the amount of time that a wastewater remains in the system. Current design methods idealize the system as a plug flow reactor and use a "residence time" based solely on the volume of the cell and the flow rate....

Kinetic design of free water surface constructed wetlands for treatment of pulp mill effluent

Creator:: Hossain, Belayet
Resource Type:: Masters Thesis

Decomposition of cattail and bulrush plant parts in a constructed wetland treating pulp mill effluent

Creator:: Walz, Anita
Abstract:: Dried cattail and bulrush plant pieces in mesh bags were incubated in the constructed wetland treating Pope & Talbot pulp mill effluent. Two ponds planted with each species and two depth ranges in each pond were chosen, to determine decomposition rates. Bags were withdrawn and analyzed at five time points...

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...

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...

Treatment of dairy wastewater in a constructed wetland system : evapotranspiration, hydrology, hydraulics, treatment performance, and nitrogen cycling processes

Creator:: Niswander, Steven Francis
Abstract:: Five unique but related studies were conducted at the Oregon State University Dairy Wetland Treatment System (OSUDWTS), Corvallis, OR. The research site consisted of six parallel wetland cells, which were built in 1992 and began receiving concentrated dairy wastewater in the fall of 1993. Hydrologic, hydraulic, and water quality data...

Constructed wetland treatment of fecal coliform in dairy pasture runoff

Creator:: Osborn, Erik C. J.
Abstract:: A constructed wetland receiving pasture runoff from a dairy in Tillamook, OR was monitored during the winter of 1997-98 in order to estimate coliform treatment efficiency during winter high flow periods. Monitoring occurred during four sampling periods, each lasting 2 to 4 days. Samples were taken every two hours from...

Antimicrobial contaminant removal by multi-stage drinking water filtration

Creator:: Rooklidge, Stephen J.
Abstract:: The fate of antimicrobials entering the aquatic environment is an increasing concern for researchers and regulators, and recent research has focused on antimicrobial contamination from point sources, such as wastewater treatment facility outfalls. The terraccumulation of antimicrobials and mobility in diffuse pollution pathways should not be overlooked as a contributor...
