One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine. [2] Many seagoing ships and submarines use desalination.
The brine disposed by the seawater desalination may disturb the ecosystem as the same amount of brine is produced as freshwater. [5] By using the brine valoristation method of wind-driven air flow by cooling the greenhouse with seawater evaporation, salt can be produced as shown in Figure 4. [5]
Seawater may have a salt concentration of 30 g/L (3%) and an EC of 50 dS/m. The standard for the determination of soil salinity is from an extract of a saturated paste of the soil, and the EC is then written as ECe. The extract is obtained by centrifugation. The salinity can more easily be measured, without centrifugation, in a 2:1 or 5:1 water ...
Seawater desalination requires more energy than the desalination of fresh water. Despite this, many seawater desalination plants have been built in response to water shortages around the world. This makes it necessary to evaluate the impacts of seawater desalination and to find ways to improve desalination technology.
More generally, desalination is the removal of salts and minerals from a substance. [15] One example is soil desalination. This is important for agriculture. It is possible to desalinate saltwater, especially sea water, to produce water for human consumption or irrigation. The by-product of the desalination process is brine. [16]
For decades, environmentalists have decried ocean desalination as an ecological disaster, while cost-savvy water managers have thumbed their noses at desal’s lofty price tag.
Large-scale desalination of seawater is another factor that would contribute to the success of agriculture farming in dry, desert environments. [36] One of the most successful plants in salt water agriculture is the halophyte. The halophyte is a salt tolerant plant whose cells are resistant to the typically detrimental effects of salt in soil. [37]
Jul. 26—With approval of a $10 million Texas Water Development Board loan, the Laguna Madre Water District will build a 10 million gallon seawater desalination plant in Port Isabel using water ...
