Desalination Increasing Our Water Resources

Today many areas of the world are experiencing droughts,resulting in a growing need to produce more fresh water. This is leading to the increase in Desalination plants, throughout the world, especially in California USA and Saudi Arabia.

Two thirds of our planet is made up of water Much of this is salt water, and impossible to drink, or use for crops. However Desalination plants can help us utilize this water and increase our supplies of fresh water for consumption and agriculture. What is desalinization and how does it work?

Desalination refers to any of several processes that remove the excess salt and other minerals from water in order to obtain fresh water suitable for for consumption or irrigation and if almost all of the salt is removed, for human consumption, sometimes producing table salt as a by product. Desalination is used in over a hundred countries, with Saudi Arabia accounting for about 24% of total world capacity. Kuwait built the world's first large-scale desalination plant in the 1960s. Kuwait is unique in that it also uses desalinated water for agriculture. The world's largest desalination plant is in Ashkelon Israel. Began operating on August 4, 2005. It is capable of producing 100 million cubic meters a year of water.

How does it work? There are 2 main methods of desalination

Reverse Osmosis. Pressure is applied to the intake water, forcing the water molecules through a semi permeable membrane. The salt molecules do not pass through the membrane, and the water that passes through becomes fresh
water.

Distillation. The intake water is heated to produce steam. The steam is then condensed to produce pure water

Desalination is a growing alternative for increasing our supplies of useable water and reliving the strains we are starting to put on our water supplies, with our increased use of this valuable resource. However it is not without some risks to our fragile environment. Most desalination plants produce hypersaline brine that must be disposed. These desalting concentrates are classified by the U.S. Environmental Protection Agency as industrial wastes. The hypersaline brine has the potential to harm marine ecosystems, especially in sea regions with low turbidity, high evaporation and hence already increased salinity. Examples are the Persian Gulf, the Red Sea, and in particular Coral Lagoons of Atolls and other tropical Islands around the world. It is up to us to operate ourDesalination plants responsibly and not allow their wastes to harm our finely balanced ecosystem.

Desalination / Distillation is one of mankind's earliest forms of water treatment, and it is still a popular treatment solution throughout the world today. In ancient
times, many civilizations used this process on their ships to convert sea water into drinking water.

Today, desalination plants are used to convert sea water to drinking water on ships and in many arid regions of the world, and to treat water in other areas that is fouled by natural and unnatural contaminants. Distillation is perhaps the one water treatment technology that most completely reduces the widest range of drinking water contaminants.
