The Middle East nations started practicing the process of desalination in a fight against water scarcity ages ago, and today, they have become the pioneer in this technology. Most of the oil rich countries like Yemen, Israel, Qatar, Saudi Arabia access sanitary water due to the process of desalination. Recently, Dubai launched UAE’s largest desalination plant in Jebel Ali. So, what exactly is this technology and why has it gained this prominence?

In a desalination plant, the process of desalination can be done in three possible ways, namely, thermal, electrical and pressure-based. These methods are usually based on certain factors like cost, available resources, energy consumption and on the type of water they can be applied on, i.e., sea water or brackish water. Middle East nations consist of the largest number of thermal plants. The process of separating pure water from salt water by distillation is used in the thermal process while using membranes to separate them is followed in the process of RO technology, i.e., Reverse Osmosis. The Thermal process involves two major technologies. They are Multi Stage Flash Distillation (MSF) and Multiple Effect Distillation (MED).

In case of a plant using MSF technology, the sea water is first heated and pressurized and then it is introduced in different cells maintained in low pressure and temperature where the feed water converts into steam. The steam is then condensed into pure water. The final product of the heated water is then reheated multiple times while the pressure keeps on reducing in every new cell. The major disadvantage in this process is that it requires more intake of salt water.

In case of Multiple Effect Distillation, the entire process remains similar to MSF desalination, however, here, the plants do not require a large flow of sea water or brine, thereby, reducing the consumption of electricity.

This process of desalination has been badly criticized for over-using energy resources with a heavy carbon footprint. One of the major disadvantages of this process is its impact on the environment, specifically on the ocean ecosystem. In this process, a huge amount of salt is discharged into the ocean which holds a huge risk of completely destroying the underwater ecosystem.

However, with technological advancements, the process of desalination has become cheaper, cleaner and more energy efficient. In fact the environmentalists of the region believe that the process of desalination have emerged as a substitute to the alternative ways of water management that have become the victims of industrial pollution.

German Chancellor Angela Merkel has told Russian President Vladimir Putin that the Middle East situation had been complicated by the US’ withdrawal from the Iran nuclear deal.

According to a statement issued by the German government, Merkel made the remarks on Friday during her meeting with Putin in Russia’s Black Sea city of Sochi, Xinhua news agency reported.

Merkel told Putin that Germany, like the rest of Europe, did not want to leave the agreement and wanted to continue to support it. With regard to the Iranian nuclear programme, the agreement gives “more security, more control and, above all, more transparency”.

But there are also topics “that have to be talked about with Iran”, Merkel said, referring to the concerns of the Iranian ballistic missile program, and the question of how to proceed after the expiration of each element of the nuclear agreement.

Merkel stressed after her talks with Putin how important it was to have an open exchange of ideas, especially if the two countries have different views, adding that the German-Russian cooperation had endured serious differences.

“But if you want to solve problems, you have to talk to each other,” Merkel was quoted as saying.

With regard to the situation in Ukraine, Merkel said the Minsk accord was the “only basis” to achieve peace in east Ukraine, and agreed with Putin that it was important to station a UN peacekeeping troop in the area.

With regard to Syria, Merkel said that Germany would continue to support UN’s mediation efforts with full force, saying it was important the already-agreed upon process of constitutional reform really got going. (IANS)
