Evaluation of Modern Irrigation Techniques with Brackish Water
… are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. Furthermore, by using drip irrigation …

Design of cost-optimized village-scale electrodialysis systems for brackish water desalination
… methods of reducing the cost of electrodialysis brackish water desalination systems, specifically for use in rural India, where 60% of the groundwater is too saline to drink. Convergence of socioeconomic and technical factors led to the insight that photovoltaic (PV) powered electrodialysis (ED) …

Computation of pseudosonic logs in shallow fresh/brackish water wells: a test case in Brunswick, Georgia
… where the principal formation fluid is fresh or brackish water. Data from four wells situated in Brunswick, Georgia were used in this study. Conventional focused resistivity logs are sensitive to beds as thin as one foot and can provide detail similar to that seen on sonic logs. Focused …

Paleontology of brackish-water faunas in two tongues of the Cannonball Formation (Paleocene, Danian), Slope and Golden Valley counties, southwestern North Dakota
… The fauna of the tongues is characteristically brackish, but three species of the L tongue mina sp., ?Haplophragmoides sp. and ?Ostrea sp.) suggest conditions of slightly higher salinity than those in which the U tongue was deposited. The two tongues are interpreted to have been deposited on …

Thermodynamic analysis of electrodialysis
… presented in this thesis is motivated by the water and energy problems our world faces today. Desalination can help alleviate the problem of water shortage by increasing the supply of fresh water. However, for desalination to play a major role in the future, it needs to be done in a …

Alternative groundwater resources in North-central Texas for the development of the Barnett Shale gas play
Texas water resources are under pressure due to population growth expected in the coming decades, increasing industrial demands, and frequent periods of drought. With this increasing demand for limited water resources it is important to explore alternative water sources within the State. One of …

Development and performance characterization of first-generation dendrimeric nanofiltration membranes
… used for oil and gas production generate brackish water as a byproduct called produced water. Desalination and reuse of produced water can potentially be a new resource for freshwater which may alleviate local and global water scarcity. Currently, reverse osmosis (RO) is the …

Electrical Conductivity and Resistivity Study of Heterogeneous Sediment in Inwood Hill Park, Manhattan, NY
… The inlet is a tidal flat, which contains brackish water; a mixture of saltwater and freshwater. The area was modified by man, built on a shell bed and contains heterogeneous sediment. One field adjacent to the inlet contains several small sinkholes. Electrical resistivity and ground …

Trace element contaminants in the Kuwait water production system
Fresh water in Kuwait is produced by non- conventional methods. About 95% of this water comes from desalinated seawater using multi-stage flash distillation technique and the remainder comes from underground brackish water. The blended water containes organic, inorganic and trace metal impurities …

Capacitive deionization performance of bi-tortuous activated carbon electrodes coated with asymmetrically charged polyelectrolytes
… are polarized to reversibly store ions from a brackish water feed in electrical double layers in the electrodes. CDI is an attractive alternative to commonly used brackish water desalination technologies like reverse osmosis and thermal distillation due to its low energy consumption and …

The geochemical evolution of saline groundwater within a fresh water aquifer south of Oakes, North Dakota
<p>An area of saline/brackish groundwater south of Oakes, North Dakota has been reported by the North Dakota State Water Commission. The concentrated water (over 12,000 mg/L of total dissolved solids) is in direct hydraulic connection with relatively fresh water and shows an abrupt change in …

An Assessment of Community-Scale Electrodialysis Desalination Systems and Improved Scale Mitigation through Pulsed Operation
Globally, rapidly developing water scarcity issues stress the need for efficient desalination practices. This thesis demonstrates electrodialysis (ED) as a potentially cost-effective high recovery desalination technology for brackish water desalination and presents novel methods of increasing …

Recent foraminifera of Trinity Bay, Texas
… is a mixture of species either endemic to the brackish-water environment or occurring in both brackish-water and marine habitats. Tests of the cosmopolitan species are calcareous whereas tests of all endemic species except one are agglutinated. Calcareous Foraminifera dominate the populations …

Electro-disinfection of Ballast Water
… as a potential secondary ballast water treatment technology. Electricity applied to bacteria laden water produced bactericidal effects, reactive oxygen species and chlorine generation which annihilated bacteria. Evaluation of electro-disinfection experiments showed titanium …

Artificial Reef Performance in Lake Pontchartrain, Louisiana
… and fish assemblages, structural integrity, water quality, and recreational use of the reefs were conducted. Findings indicated that the reefs support estuarine fauna and have enhanced fishing and diving opportunities. In addition, a framework for reef monitoring was developed to guide future …

Shock electrodialysis for water purification and electrostatic correlations in electrolytes
… systems have become an important part of many water supply networks, and they have also been considered as solutions for water shortages and in areas in which access to clean and safe water is still a problem. The quality of available water that is encountered in these situations tends to vary …

Microfluidic engineering of water purification
The demand for clean water has been increasing for several reasons, such as rapid industrialization of developing countries, environmental pollution and climate change, and development of biofuels and the resulting irrigation growth. To meet the needs for this growing demand for clean water, …
