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.
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.
Still, Mitchell said he thinks desalination has a place in California’s water portfolio,and noted that it has already proved viable in Australia and Israel, which gets nearly 90% of its drinking ...
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]
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 ...
The small desert nation reuses 86% of its wastewater as of 2011, and 40% of the total water used by agriculture was reclaimed wastewater. [10] Desalination, brackish, or effluent water also accounts for 44% of Israel's water supply, [11] and the world's largest seawater desalination plant is the Sorek Desalination Plant located in Tel Aviv. [12]
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]
