Desalination is the process of purifying saline water to make it fit for human consumption. Of all the water on earth, 97.5% of it is saltwater with only 2.5% being fresh water. However, over two-thirds of the fresh water is trapped in glaciers and ice caps in the polar regions of the globe which leaves only 0.83% of the total water on earth being accessible clean water. While some countries have the privilege of having many lakes and rivers within their border (such as Canada), others are not as lucky and can only rely on desalinating marine water to cater for their local water demands. Desalination occurs through two primary processes of distillation and reverses osmosis.
How to desalinate seawater?
One of the most cost-effective ways to desalinate seawater is through reverse-osmosis, which is just a filter with holes so small only H2O molecules can fit through . But it is susceptible to fouling, chlorine destroys the polymer film, and you have to bypass a significant stream around the membrane to prevent the salt from accumulating and precipitating. The system requires high pressure pumps, prefilters, and regular change-outs of the costly membrane units. This requires a large $$ investment and a decent selling price of the purified water to make the venture attractive to business investme
What is Kuwait known for?
Kuwait is a desert country located in the Middle East.

Where is desalination most important?
West Asia (the Middle East) is one of the regions with severe water scarcity in the world, where the climate is hot, precipitation is scarce and the land is dry. At the same time, it is the region with the world's most concentrated oil resources and strong economic strength. Therefore, it has an urgent need for desalination technology and equipment, and has the economic foundation for the industrialization of desalination. Therefore, the region has become the main distribution area of the world's desalination plants. The total water production of desalination plants in Saudi Arabia, UAE, Kuwait, Qatar and Bahrain in this region accounts for 44.3% of the global total. In the coastal areas of the Persian Gulf, some countries have accounted for 80% to 90% of the country's freshwater use. In contrast, the world's first modern desalination plant, the birthplace of the United States, only 15% of the world's seawater desalination, while the more developed Europe, accounting for only 12%. According to current data, Saudi Arabia is still the world's largest producer of desalinated water, accounting for about 18% of global production. 70% of Israel's water comes from seawater desalination, and the world's leading desalination company—IDE, has also been born.

What makes water saline?
What do we mean by "saline water?" Water that is saline contains significant amounts (referred to as "concentrations") of dissolved salts. In this case, the concentration is the amount (by weight) of salt in water, as expressed in "parts per million" (ppm).
The worldwide need for freshwater
The scarcity of freshwater resources and the need for additional water supplies is already critical in many arid regions of the world and will be increasingly important in the future. Many arid areas simply do not have freshwater resources in the form of surface water such as rivers and lakes.
Another method: Reverse osmosis
Another way saline water is desalinized is by the "reverse osmosis" procedure. In most simplistic terms, water, containing dissolved salt molecules, is forced through a semipermiable membrane (essentially a filter), in which the larger salt molecules do not get through the membrane holes but the smaller water molecules do.
Desalination is not modern science
Distillation desalination 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.

What is desalination in agriculture?
Desalination is a process that takes away mineral components from saline water. More generally, desalination refers to the removal of salts and minerals from a target substance , as in soil desalination, which is an issue for agriculture.
What are the two methods of desalination?
The most common desalination processes are distillation and reverse osmosis. There are several methods. Each has advantages and disadvantages but all are useful. The methods can be divided into membrane-based (e.g., reverse osmosis) and thermal-based (e.g., multistage flash distillation) methods.
How does solar distillation work?
Solar distillation mimics the natural water cycle, in which the sun heats sea water enough for evaporation to occur. After evaporation, the water vapor is condensed onto a cool surface. There are two types of solar desalination. The former one is using photovoltaic cells which converts solar energy to electrical energy to power the desalination process. The latter one utilises the solar energy in the heat form itself and is known as solar thermal powered desalination.
Where is solar desalination done?
AquaDania's WaterStillar has been installed at Dahab, Egypt, and in Playa del Carmen, Mexico. In this approach, a solar thermal collector measuring two square metres can distill from 40 to 60 litres per day from any local water source – five times more than conventional stills. It eliminates the need for plastic PET bottles or energy-consuming water transport. In Central California, a startup company WaterFX is developing a solar-powered method of desalination that can enable the use of local water, including runoff water that can be treated and used again. Salty groundwater in the region would be treated to become freshwater, and in areas near the ocean, seawater could be treated.
