Why do places like Dubai rely on seawater desalination for their freshwater needs?

 


Desalination is used more frequently to ensure a reliable supply of water, but it is still seen as a costly, environmentally harmful option that only wealthy nations can afford. In this article, we reframe desalination as a comprehensive, climate change-mitigating, and water security option rather than as a last resort. Read below to find out more about desalacion eficiente de agua de mar.

SEAWATER DESALINATION: A PLAN TO CONTROL SCARCITY?

One of the most valuable resources in the world is water. More than 40% of the earth's population is already impacted by its scarcity, according to the UN.  Desalination, which entails removing the minerals (mainly salt) from seawater via physical and chemical processes, is one of them and is not wholly new. In the upcoming years, it will be crucial to boosting desalination plant capacity while lowering their environmental impact.

Our earth is 70% covered in water. Therefore, it is natural to believe that there is plenty. Only 3% of the world's water supply is freshwater, and of that, two-thirds is either unavailable because it is frozen or inaccessible. In the world, 1.1 billion people lack access to clean water, and 2.7 billion experience scarcity for at least one month each year. Desalacion eficiente de agua de mar can be useful in these situations since, paradoxically, many regions with a shortage of fresh water are also relatively close to the ocean.

WHAT IS DESALINATION?

Desalination is the procedure used to remove dissolved mineral salts from water. Currently, one of the most popular methods for obtaining fresh water for use in agriculture or human consumption when applied to seawater.

Desalacion eficiente de agua de mar happens naturally as part of the water cycle when saltwater evaporates, leaving behind salt and generating clouds that result in rain. Aristotle noted that seawater would evaporate and condense into fresh and clean water. Da Vinci understood that it was simple to get using a still.

In the centuries that followed, saltwater desalination was utilized mostly on ships and submarines to supply the crew members with fresh water during lengthy voyages. But this method wasn't widely accessible until the industrial revolution, and particularly not until the invention of desalination facilities.

 

HOW DOES A DRY COUNTRY LIKE SAUDI ARABIA OBTAIN ITS WATER SUPPLY?


Saudi Arabia is a country without any rivers at all. It uses twice as much water as any other developing country in the world, even though it has a few lakes, undersea sources, and oases in the desert.

Given this information, the next logical question for any potential visitor to Dubai, Bahrain, or any other city is: How does Saudi Arabia obtain its supply of water for daily habits, cooking at those opulent hotels, and operating the upscale malls & carrying out other day-to-day activities?


Saudi Arabia heavily depends on two water sources: groundwater and water derived from facilities that desalinate seawater to remove the salt. A large layer of water that can be obtained through wells, borewells, etc., is found beneath the earth's crust, where groundwater is derived from.

Aquifers that were created when there was water instead of the desert are also found beneath Saudi Arabian soil. There is hardly enough water left to last another ten years because of Arab water squandering in agriculture and religious rites.

Saudi Arabia is the world's largest producer of desalinated water. It is the water that is derived from salty seawater. However, desalacion eficiente de agua de mar is an extremely energy-intensive procedure that costs a lot of money.

Because the Arabs mainly depend on oil extraction as a source of wealth.  Therefore, it has no promising future. And when the nation runs out of oil, they won't be able to pay for all the money they invested in running desalination plants.


The solution


The Saudi Arabia government has taken a few steps to stop water depletion, which has already become so severe that growing wheat crops is prohibited. The Saudi government has also permitted the treatment of sewage water for use in agriculture, the use of water from mosques for toilet flushing, and the distribution of free shower heads & faucets to rural residents to discourage the use of groundwater.

So, be aware that the next time you travel to Saudi Arabia, you will be in a place where water truly is liquid gold.

WHAT IS THE REASON DUBAI USES SEAWATER DESALINATION?

The UAE must find a sustainable desalination method to meet its long-term water needs because there aren't any freshwater sources nearby. One solution is to link renewable energy sources with Desalacion eficiente de agua de mar devices.

When using reverse osmosis or multiple-effect distillation (MED), or multiple-stage flash distillation to produce energy, the majority of the water used in the United Arab Emirates is desalinated (MSF).

Research claims that from 2008 to 2012, the water demand increased primarily at a pace of 35.8%. While water output was 393,879 million imperial gallons per year, the capacity factor for desalination & groundwater was 1,586 million imperial gallons per day.

Conclusion:

Desalination fulfills a crucial need all around the world since there is a growing need for water. By releasing constrained fresh water supplies, this form of therapy helps people become healthier & wealthier while also benefitting the environment. Water's crucial function in trade and industry contributes to it by making people wealthy. Water is essential for both life and business. In addition to being depleted, freshwater resources are actually abused & have been for a very long time.
