High Recovery Desalting Of Brackish Water By Electrodialysis: Field Tests At Yuma Desalting Test Facility & At La Verkin Springs, United States Department Of The Interior, Bureau Of Reclamation

Water

An ED (electrodialysis pilot plant achieved high desalting recoveries of nearly 95 percent at the YDTF (Yuma Desalting Test Facility, Arizona) and 92 percent at LVS (La Verkin Springs, Utah) during over 4000 hours of operation. Brine TDS (total dissolved solids) concentrations of nearly 100 000 g/m³ were obtained at LVS, which is a greater brine concentration than is possible using RO (reverse osmosis). The LVS required ED energy (while producing a product TDS concentration of about 1000 g/m³) is estimated to be about one-third the energy requirements of a commercially available distillation brine concentrator. Lowering product …

Sewage sludge is a product of waste water treatment plants that function as environmentally acceptable pollution control facilities. In past years most of the sludge had been landfilled, dumped at sea or buried. But environmental and economic considerations have resulted in greater interest in its application on cropland.

The Historical Development Of The Yakima-Tieton Irrigation District And Its Present Effect On Life In The Area Encompassing The District, Werner E. Lemke

All Graduate Projects

Irrigation played a very important role in the development of the Yakima Valley as we know it today. The Yakima-Tieton Irrigation District was chosen to show how an irrigation system functions and the part it plays on the lives of the plants, animals and people in its area. A brief historical study of the Tieton Division of the Yakima Project was made. The construction of the Tieton Unit was studied. A slide lecture with an accompanying tape was developed to acquaint junior high school students with the purpose, function and affects of the Yakima-Tieton Irrigation District.

Effect Of Small Aspen Clearcuts On Water Yield And Water Quality, United States Department Of Agriculture, Forest Service

Forestry

Streamflow and water quality were monitored in a paired watershed study involving the removal of 20 percent of the aspen (on 13 percent of the area) in five small clearcuts from a 217-acre (88-ha) catchment. There were no significant changes in peak flow, timing, or annual yield during the 4 years of posttreatment monitoring. Significant changes in pH, calcium, magnesium, and nitrates in the snowmelt streamflow from ephemeral subdrainages occurred the second year after cutting. At least some of the differences were attributed to the chemistry of the 1976-77 snowfall, which was also significantly different from snow sampled in the …

Water Erosion On Potato Land During The 1983 Growing Season Donnybrook, D J. Mcfarlane

Resource management technical reports

Soil losses over a three month period varied from 10 to 49 mm.. Soil loss was most highly correlated with length of slope of the plots. Other important factors appeared to be slope angle and soil textures. Grade furrows appear to be the best method of breaking-up long slope lengths. The low capacity of the furrows requires them to be on grades of about 4 to 4 per cent to prevent siltation and overtopping during high density storms.

A Microsystem Sediment-Water Simulation Study For The Proposed Jordanelle Reservoir, Heber City, Utah, United States Department Of The Interior, Bureau Of Reclamation

Water

The technique of microsystem sediment-water simulation was used to predict water quality data for the proposed Jordanelle Reservoir, Heber City, Utah. Simulation microsystems were prepared for four sites located in the north arm of the reservoir basin including two sites located in an abandoned acid mine tailings pond. Data obtained from the tailings pond microsystems indicated that low pH water and high trace metal concentrations will exist in the north arm of the reservoir. These data suggested that some kind of membrane or compacted earth lining will be necessary to seal and contain the mine spoilage. Other sites in the …

Transport And Fate Of River Discharge On The Continental Shelf Of The Southeastern United States, J. O. Blanton, L. P. Atkinson

CCPO Publications

We have analyzed 8 years of wind and salinity data from a frontal zone in a region of the inner continental shelf off the southeastern United States. The changes in low‐salinity water stored in the frontal zone have been parameterized by analyzing the monthly rate of change in freshwater content. When the rate of change in freshwater content was negative, we interpreted this as a loss of low‐salinity water from the frontal zone. When this parameter was compared with seasonally averaged alongshore wind stress, the rate of loss was independent of the alongshore wind stress magnitude until threshold of about …

Effects Of Water On The Fate Of Herbicides In Irrigated Soils, Terry L. Lavy

Technical Reports

The wide use of soil-applied herbicides necessitates an understanding of their fate in soil if we are to use them in the most beneficial manner. All herbicides have some degree of water solubility and the field performance of many are dependent on ample, timely availability of soil moisture. It is important that different aspects of soil-herbicide-water interactions be thoroughly investigated. An excess use of water for irrigation purposes can result in the downward movement of herbicides in the soil profile. Subsoils are less adsorptive and a decreased degradation potential exists when herbicides move below the top 15 cm. In sandy …

A Salt And Water Balance Model For A Silt Loam Soil Cropped To Rice And Soybean, J. T. Gilmour, J. A. Ferguson, B. R. Wells

Technical Reports

A computer model was developed which described salt and water balances for a silt loam soil common to the Grand Praire physiographic region of Arkansas. A ten year period of weather data (1966-75) was used as input data for two divergent cases in regard to salt accumulation. Case one was a rice-soybean rotation with soybean irrigated, while case two was a rice-soybean-soybean rotation with soybean not irrigated. Salts considered were calcium, magnesium, sodium, sulfate and chloride as well as the precipitate, calcium carbonate. Where soybeans were not irrigated less evapotranspiration, more infiltration and less runoff were observed during the fallow …

Chemistry Of Organic N-Chloramines, Formation Of Arenesulfonamides By Derivatization Of Organic N-Chloramine With Sodium Arenesulfinate, Katherine F. Bowdring

Chemistry & Biochemistry Theses & Dissertations

Organic N-chloramines are recognized by-products of chlorinated water systems. Because of their chemistry, none have been isolated or identified.

This paper discusses a method for the derivatization of the organic N-chloramines based on a nucleophillic substitution mechanism. N-Chloro derivatives of amines of various structures were studied including primary and secondary aliphatic amines, as well as amino acids. The effect of the presence of other functional groups including aromatic and unsaturated systems was investigated.

Derivatization was done by three different methods, one involving derivatization of the pure N-chloramine, and two involving derivatizations of the N-chloramine generated in situ. Seventeen arenesulfonamides have …

A Technique For The Isolation And Identification Of Aliphatic Amines In Water, Peter Alan Drew

Chemistry & Biochemistry Theses & Dissertations

Small, aliphatic amines added to a basic, aqueous solution (16.2 L) at a concentration of 100 parts per billion were isolated by sorption on a small column of macroreticular resin. The amines were eluted with diethyl ether; the eluate concentrated, and the compounds separated and identified by gas chromatography. The efficiency of the recovery of a-nines ranged from 5 to 28%.

A protocol for derivatizing pyrrolidine and n-pentylamine in ether with fluorinated acylating agents was developed. The method was found to be adequate for the detection of approximately 13 micrograms of &-nines in concentrated ether extract.

Assessment Of The Radiological Impact Of The Inactive Uranium-Mill Tailings At Mexican Hat, Utah, F. F. Haywood, W. A. Goldsmith, B. S. Ellis, H. M. Hubbard Jr., W. F. Fox, W. H. Shinpaugh, Oak Ridge National Laboratory

All U.S. Government Documents (Utah Regional Depository)

High surface soil concentrations of 226Ra and high above-ground measurements of gamma-ray intensity in the vicinity of the inactive uranium-mill tailings at Mexican Hat show both wind and water erosion of the tailings. The former mill area, occupied by a trade school at the time of this survey, shows a comparatively high level of contamination, probably from unprocessed ore on the surface of the ore storage area near the location of the former mill buildings. However, the estimated health effect of exposure to gamma rays during a 2000-hr work year in the area represents an increase of 0.1% in the …
