Seawater can be purified, and there will be a lot of water resources in the world

Seawater can be purified, distilled, disinfected and other measures to meet the standard of drinking water, but due to the high cost, it is rarely used except in some arid and expensive places. For example, in some places in Arabia, where there is more oil than water, drinking water is obtained by purification and foreign imports.

Yes, if it were all seawater, we could drink it, but where would they, the sea creatures, go? It triggers aconsciousness in more animals. Besides, when mankind knows the good news from heaven, it may be even more wasteful of water than it is now, and by that time, there will only be those tears of regret left in the world.

If it all turns to fresh water, won't those sea creatures die, then what will we eat for seafood in the future? Won't the entire ecological environment and food chain be destroyed, and will people still be in the world?

The flow of water makes it too serious.

Cost is secondary!

Technology is very problematic!

There is less fresh water and more seawater, but if we don't protect the water resources, the seawater is polluted, and there is no water!

yes, I want to do that too.

That way there will be no shortage of water.

There's so much water in the sea that you can drink it casually.

Generally speaking, the seawater in the normal part is not directly drinkable, and because of the large number of impurities and the high content of metal salts, it cannot be directly drunk, and if it is directly irrigated with seawater, it may also cause problems for plantsTherefore, normal seawater is difficult to be used by people, so the purified seawater is relatively less impurities, and the relatively pure seawater that has been filtered through multiple layers can be directly drunk. <>

1. Generally speaking, normal seawater purification is to filter out other components in seawater, and then obtain purified pure water. In fact, for us, seawater desalination in the normal sense is a complex process, and generally after impurity treatment, seawater components are treated to obtain relatively pure pure water, and there are many processes inside, and simple purification is difficult to meet the drinking standard. <>

2. Generally speaking, the water obtained by distillation can be directly drunk, and it can also be purified at multiple levels to obtain drinking pure water. In fact, for us, normal people want to get drinkable seawater, then can only be distilled to get pure water, seawater purification is a relatively complex project, it takes a lot of processes to be able to obtain, water to meet the drinking standard, and it is precisely because of this that in general, it is difficult to drink seawater that is only treated with simple impurities. <>

3. There are relatively many impurities in seawater, and the metal content in it is difficult to meet the drinking standard, so the directly filtered water is undrinkable. In fact, it has to be said that there are still many deficiencies compared with fresh water, and it is precisely because of this that seawater desalination is a relatively complex process, not only filtering impurities in seawater, but also filtering other components to obtain pure water, so if there is no relatively careful purification process, the obtained water is not directly drinkable.

In fact, for us, seawater purification is only to filter impurities and other components in seawater to obtain pure water, and the purification process is relatively numerous, so the general purified water is unable to meet the drinking standard.

It cannot be drunk directly, seawater purification refers to marine organisms such as seaweed, which can eat part of the garbage to achieve the effect of initial purification, and the salt content in it is very high, so it cannot be drunk directly.

Basically, it is physical purification, using the principle of osmotic pressure to separate fresh water from seawater, and what is separated is fresh water, but other substances in seawater cannot be separated, which is often harmful to the body, because the diameter is too small, so it cannot be drunk directly.

The principle of purification is distillation, which uses the different boiling points of water and other substances to separate water from other substances, but the resulting water is distilled water, which also requires special treatment before drinking.

Yes, there is already desalination technology.

Desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology that realizes the utilization of water resources, which can increase the total amount of fresh water without being affected by time, space and climate, and can ensure a stable water supply such as drinking water for coastal residents and water supply for industrial boilers.

The process of obtaining fresh water from seawater is called desalination. The seawater desalination method used now has seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method that can achieve profitability, and the reverse osmosis method of reverse osmosis membrane is used to quickly occupy the market with its advantages of simple equipment, easy maintenance and equipment modularization, and gradually replace the distillation method to become the most widely used method.

There are more than 100 scientific research institutions in more than 10 countries in the world that are conducting research on seawater desalination, and there are hundreds of seawater desalination facilities of different structures and different capacities in operation. A large, modern desalination plant can produce thousands, tens of thousands, or even nearly a million tons of fresh water per day. The cost of desalinated water is decreasing, and in some countries it has been reduced to about the same level as tap water.

In some areas, the amount of water desalinated has reached the scale of national and municipal water supply.

No, because the cost of seawater freshwater machines is very high, and the technology is not yet mature, so it cannot be universally distributed worldwide.

There is a process in which people still need to conserve water. After all, the purification of seawater is purification, in fact, there are many freshwater resources now, so not everyone can use it, but people can't develop and use it, and it will definitely cost more or less money and energy.

In my opinion, it is only temporary, it must be completely solved, and it must not pollute the water source, if the water is not clean, are you willing to drink it?

Water resources on Earth.

The Earth's water resources, in a broad sense, refer to the total amount of water in the hydrosphere. Since seawater is difficult to use directly, we mainly refer to freshwater resources on land. Through the water circulation, the fresh water on land can be continuously renewed and replenished to meet the needs of human production and life.

In fact, the total amount of freshwater resources on land accounts for only 2 53 of the total water bodies on Earth, and most of them are solid glaciers mainly distributed in the North and South Poles. Although scientists are studying how to use glaciers, they cannot be used on a large scale under current technical conditions. In addition, groundwater has a large reserve of fresh water, but most of it is deep groundwater, and it is rarely exploited.

At present, the freshwater resources that are relatively easy for human beings to use are mainly river water, freshwater lake water and shallow groundwater. These freshwater reserves account for only 0.3 percent of all freshwater and 7/100,000 of the world's total water volume, i.e. about 9,000 cubic kilometres of freshwater resources are actually used effectively in the world every year.

From the perspective of movement and renewal, river water is the most important and has the closest relationship with human beings. River water has the characteristics of fast renewal and short cycle period. Scientists have divided water resources into static and dynamic water resources.

Static water resources include: glaciers, inland lakes, and deep groundwater, which have a long cycle and slow renewal, and are not easy to recover in the short term once polluted. Dynamic water resources include river water and shallow groundwater, which circulate quickly, renew quickly, and have a short alternating period, which can be restored in a short period of time after utilization.

Therefore, when human beings develop water resources, they must make rational and full use of water resources in accordance with the laws of the water cycle. Only by promoting the renewal of water resources and cherishing water resources by everyone can we use water resources sustainably.

When all the seawater on Earth turns into fresh water, the first reaction for humans is that they will no longer be able to eat salt so easily. Then you will find that when all the seawater on the earth turns into fresh water, life will change a little.

First, the earth is seriously polluted.

We know that the salt content in seawater is very high, which is why seawater is very salty in the mouth, and because seawater is very salty, many bacteria can not survive in the sea, a large seawater becomes fresh water, so many bacteria that can survive in the heavy snow are easy to come to the sea, and will not be killed, so that the whole sea will be filled with all kinds of bacteria, which will have a certain impact on the ecological environment of the ocean, and the entire marine ecology will undergo some changes. For example, some fish that used to be able to survive in the ocean are no longer able to survive.

2. Chlorella outbreaks.

In addition, if the sea turns to fresh water, there is a high chance that various green algae will float on the surface of the sea during the hot summer months, and the whole sea will turn green over time. The decay of green algae will produce a large amount of methane gas, and methane gas will bring a greenhouse effect to the earth, so as soon as there are more green algae, the temperature of the earth's surface may rise, and the greenhouse effect will become more and more obvious.

3. Changes in species in the ocean.

When the sea water becomes fresh water, many animals and plants that can not survive in the ocean can survive in the ocean, that is to say, the wild grass on land can grow all the way to the edge of the sea, and even enter the ocean to replace other marine plants, the beach will also be full of green plants, a large number of freshwater animals and plants will enter the sea to replace the original extinct marine life, the marine ecosystem will be completely changed, and the marine world will show another scene, which is likely to be green. At this time, more new species will soon be accepted by humans, and the cost of obtaining salt will continue to increase, but it will be easy to irrigate the desert directly with seawater.

It will cause many organisms to die, affect the diversity of organisms, lead to an imbalance in the ecosystem, and have serious consequences, so that the earth will not be able to function benignly.

There is a high probability that the world will disappear, and if all the water in the world is freshwater, then the mobility will become worse and worse, and the oceans will not be able to provide precipitation and heat to the land, and the land will disappear.

The world will become ecologically unbalanced, because it is not suitable for all species.

This will lead to the death of a large number of fish, and the fish of the ocean are completely different from the freshwater fish, and will lead to the extinction of many fish, many marine life.

The water quality on the earth will undergo a big change, and some fish may not be able to grow, of course, it will meet the water consumption of our human beings, and the ecological balance in the ocean will be destroyed.

The world will not be very good, and if there is only fresh water, people will not be able to extract the salt content, and their bodies will become very weak.

If the sea water is all freshwater, it will mean that the earth is not a silicate planet, because after all, the water cycle on the earth will dissolve the minerals in the soil in different ways, and 80% of the more than 100 elements known in the world can be found in seawater. If seawater becomes freshwater, that is, there is no salt in it, the world will undergo a series of profound changes. We all know that it is inseparable from people's daily life and production.

The earth's seawater is inexhaustible, what if it were used to irrigate the desert? It is well known that the proportion of oceans on Earth is higher than that of land. The oceans cover 71% of the Earth's surface area and the land covers 29% of the Earth's surface area.

This is also an important reason why the earth is called "water ball". Most of the water on Earth is in the form of seawater. On the earth, where human beings live, the total land and sea area is about 100 million square kilometers, of which the land area is about 100 million square kilometers, accounting for only 29% of the total global area, while other regions are surrounded by oceans.

Although the earth has abundant water resources, the only freshwater resources that humans can drink directly are all water, and among them, water scarcity has become a problem in today's world.

The formation of the desert is perennially high temperature and drought, the surface is unusually dry and loose, it is a special geographical environment and one of the harshest environments on the earth, and natural disasters such as sandstorms often occur, which are very harmful to humans and nature, there are 13 regions on the earth, and the desert environment exists, especially the countries of the Middle East are called deserts. Water resources are so scarce in these areas that it seems to us impossible to go to war over the seizure of water resources on a regular basis, but there is a belief that the purpose of diverting seawater into the desert is to change the dry environment of the desert. Sea water can condense their deserts, evaporating to form water vapor that brings precipitation.

But the results were not satisfactory. Not only did it not solve the problem of drought, but it also caused more damage to the local terrain. The salt content in the seawater is high, and after the seawater evaporates, a lot of salt remains on the land, and the local terrain becomes hydrochloric acid, shrinking the suitable place for residents to live, causing a series of losses.

This is the exact opposite of what people intended to introduce seawater.

If the treated seawater can be transported to the desert area without the salt in the seawater, it is impossible to wonder whether it will have the effect of improving the arid environment of the desert. This is a real situation. Indeed, some have succeeded in introducing seawater into the desert, known as desalination irrigation, which is too costly for many countries to afford.
