Reaeration in small mountain streams

Creator:: Holtje, Ralph Kenneth
Abstract:: Fishery biologists and watershed management specialists have recently begun to investigate the pollutional threat posed by organic debris left in or near the forest watercourses. Oxygen content in some streams has fallen below the limits required for fish survival. The biochemical oxygen demand exerted by the debris and the reaeration...

Protein adsorption on chitosan-polyanion complexes : application to aqueous food processing wastes

Creator:: Savant, Vivek
Abstract:: Chitosan has been proposed as a "natural" coagulating agent to solve wastewater problems. The main hindrance in this commercial chitosan application has been its low cost effectiveness. The hypothesis in our research is that chitosan complexes with natural polyanions is more effective than chitosan alone, particularly in recovering low concentration...

Solar disinfection of drinking water : Effectiveness in peri-urban households in Siddhipur Village, Kathmandu Valley, Nepal

Creator:: Rainey, Rochelle C.
Abstract:: The study examined pH, turbidity, and fecal contamination of drinking water from household water storage containers, wells and taps, and the Godawari River, and tested the effectiveness of solar disinfection (SODIS) in reducing levels of fecal contamination from household containers. Second, the study investigated the relationship between use of SODIS...

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...

Nonthermal Plasma Microreaction Engineering for Gas and Liquid Processing

Creator:: Pommerenck, Justin
Abstract:: Atmospheric pressure plasma is non-thermal at millimeter to micrometer separations. It represents an alternative low exergy initiator of many chemical reactions. In many instances heat, light or sound are not efficient providers of the necessary energy to overcome chemical activation barriers. The focus of this research is applying dc nonthermal...

Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

Microbial fuel cell for wastewater treatment : heavy metal removal, sewage sludge treatment, and its potential application in wastewater reuse in irrigation

Creator:: Abourached, Carole
Abstract:: While water scarcity and energy demand are continuously increasing in the world, alternative sources are needed to meet the requirement of a growing population. Microbial Fuel Cell (MFC) is a sustainable technology that converts organic matter in wastewater into electricity, thus it can be a potential alternative source for water...

Essays of Land Use Changes, Open Space, and Water Pollution

Creator:: Hagimoto, Toru
Abstract:: Land use is one of the leading factors that cause environmental degradation, such as water pollution, open space contraction and habitat loss. This dissertation consists of three essays. First paper investigates the relationship between land use and water pollution. Combining land use choice model and water pollution data, I simulate...
