Evaluation of Nitrate Treatment Methods Under Uncertainty
There are several methods of removing nitrate from drinking water with varying degrees of cost and system perfonnance. In this study, the cost-effectiveness of the following nitrate removal...
Electro-Osmotic Mobility Measurement for Kaolinite Clay
Review of Technologies for In-Situ Cleanup of DNAPLs
Colloidal Fouling of Reverse Osmosis Membranes
Experiments on the fouling of thin film composite and cellulose acetate reverse osmosis membranes by aluminum oxide colloids are reported. Fouling was significant at high ionic strengths,...
Treatment of Drinking Water Containing Bromate and Bromide Ions
Granular activated carbon and reverse osmosis nanofiltration and hyperfiltration were examined for both bromate and bromide ion removal using surface treated water in New Jersey. Bromate...
Electro-Osmotic Removal of Nitrates from Soils
Nitrate migration to ground and surface waters is a serious U.S. contamination threat. Electro-osmosis may be a more effective means for soil reclamation than leaching or chemical treatment....
Brackish Groundwater Desalting in Southern California: A Summary of Case Studies
Evaluation of the City of Venice Urban Reuse Program
The City of Venice is located on the Gulf of Mexico in west central Florida. With a mild sub-tropical climate and coastal location, the small community is a prime target for rapid development....

Validity of Electro-Osmosis for Soil Decontamination
The subject matter of this paper is electro-osmosis in fine grained soils. A simple instrument has been developed to simulate this phenomena in the laboratory. A series of experiments...
Economic Evaluation of Treatment Alternatives for Nitrate-Contaminated Water Supplies
This paper discusses the economic feasibility of removing nitrates from water supplies. Potential nitrate treatment methods include ion exchange, reverse osmosis, bio-denitrification,...
Development of a Two-Stage Membrane-Based Wash-Water Reclamation Subsystem
A two-stage membrane-based subsystem was designed and constructed to enable the recycle of wash waters generated in space. The first stage is a fouling-resistant tube-side-feed hollow-fiber...
Agricultural Contaminants Removal from Groundwater by Carbon and Reverse Osmosis
Conventional Machinery/Unconventional Applications
The U. S. Bureau of Reclamation has become increasingly involved in small-scale hydroelectric projects involving unconventional applications for conventional hydraulic machinery. One ongoing...
