Is Israel s seawater extraction technology mature, and what devices are needed?

Israel's economy is dominated by science and technology, agriculture, electronics, biological engineering, military instruments and chemicals, and the manufacturing industry is basically abandoned. Israel extracts and processes potassium chloride fertilizer from seawater, which is exported to China in large quantities. <>

Israel is dry and rainless, and has been facing a state of water shortage for a long time, so fresh water resources are very scarce, so they need to use seawater extraction technology to obtain fresh water resources, we all know that water is the source of life, and for a country, the safety of freshwater resources is also extremely important, so Israel's seawater extraction technology is mature. <>

Israel's technology for extracting seawater is based on the working principle of a reverse osmosis desalination system, which uses semi-permeable membranes that allow only fresh water to pass through and no other components to pass through.

The reverse osmosis desalination device is first to extract the seawater, carry out preliminary treatment, reduce the turbidity of the seawater, prevent the growth of bacteria, algae and other microorganisms, and then use a special high-pressure pump to pressurize the seawater into the reverse osmosis membrane, due to the high salt content of the seawater, so the seawater reverse osmosis membrane must have a high desalination rate, corrosion resistance, high pressure resistance, anti-pollution and other characteristics, after the reverse osmosis membrane treatment of the seawater, its salt content is greatly reduced, TDS content from 36000 mg to about 200 mg liters. The desalinated water quality is even better than tap water, so that it can be used by industry, commerce, residents, ships and ships.

The seawater desalination equipment mainly adopts the infiltration concept of reverse osmosis membrane, which uses the principle of osmosis to filter the salt in the seawater with the reverse osmosis membrane, and flow out of the concentrated water, leaving the clean water that can be drunk, which flows out with the pipeline for the next step of treatment. This process becomes the osmotic pressure, the appropriate pressure of the water, the impurities and salts in the water are removed, leaving clean water, and the purpose of reverse osmosis desalination is achieved.

As a country with an extreme shortage of freshwater resources, Israel uses seawater extraction technology not only to support its own economy and agriculture, but also to promote the development of other neighboring countries and make efficient use of seawater.

It is very mature and requires various equipment and systems to serve seawater desalination projects, such as seawater desalination devices, seawater filtration devices, seawater disinfection devices, and seawater distribution devices, all of which have reached the international leading level.

Israel's seawater extraction technology is a leading position in the international community, and its technology is now very mature, and the main equipment required for seawater extraction technology is to require a large number of chemical agents to kill microorganisms, and also need a small karst to filter microorganisms.

Israel's seawater extraction technology is already at a fairly mature stage, and the main devices are dope pumps, seawater pumps, desalinated seawater heaters, desalinated seawater storage tanks, and so on.

Israel's technology for extracting seawater is mature.

Device: reverse osmosis seawater desalination device, first of all, the seawater is extracted for preliminary treatment, reduce the turbidity of seawater, prevent the growth of bacteria and algae and other microorganisms, and then use a special high-pressure pump to pressurize the seawater to enter the reverse osmosis membrane, because the seawater has high salt content, so the seawater reverse osmosis membrane must have the characteristics of high desalination rate, corrosion resistance, high pressure resistance and pollution resistance. After reverse osmosis membrane treatment, the salt content of seawater is greatly reduced, and the TDS content is increased from 36,000 mg1 to about 200 mg1 liter.

Israel's seawater extraction technology is still very mature, they have the world's top seawater desalination technology, they use the most distillation and reverse osmosis device, distillation is to heat seawater, so that the steam rises into the pipeline, and then collect, while the reverse osmosis device is the use of reverse osmosis membrane pressure on both sides of the different pressure, so that only the water molecules in the seawater pass through the reverse osmosis membrane.

The Negev desert region in southern Israel is perennially dry and water-scarce, and the Lake Galilee in the north is the only freshwater lake in Israel and its largest and most important source of drinking water and reservoir. In order to solve the problem of water use in the southern region, Israel put into operation in 1964 the national water diversion project "North-South Water Diversion", which uses a 300-kilometer-long water pipeline to transport the abundant water resources in the north to the arid and water-scarce south. At the same time, Israel is committed to improving the efficiency of water resource utilization, and has formed an intelligent water conservancy management system represented by drip irrigation technology, with a recycling water utilization rate of up to 75%, ranking first in the world.

However, no amount of water efficiency can change the fact that there is not enough natural freshwater. Especially as Israel's economy grows and its population increases, there is a growing gap between freshwater supply and demand. Successive droughts in the mid-90s, combined with the over-pumping of freshwater resources, left the Lake of Galilee regularly below the safety red line, a direct threat to Israel's water security.

Israel, on the other hand, borders the Mediterranean Sea and has a long coastline. Therefore, the Israeli Water Resources Commission believes that the only fundamental solution to the water problem is through the desalination of seawater. To this end, in 1999, Israel** formulated a "large-scale desalination plan" to alleviate the contradiction between supply and demand of fresh water.

It can be drunk as is, because Israel's desalination technology is very mature.

The production of fresh water with seawater desalination technology can only make fresh water meet human drinking water standards, and it is better to boil it for drinking.

Although it has become fresh water, there are still a lot of microorganisms in the water, and further treatment is required before drinking.
