Chapter 219 Direction

"Our ultrafiltration membrane is amazing, it reduces the amount of wastewater to only one thousandth!" It is worthy of the name of ultrafiltration, as such a superior filtration membrane was born right before his eyes. Although he only did some insignificant auxiliary work, he was still proud of it.

"I dare say that this small filter membrane has an economic value of no less than 100 billion!"

As the most important element for human survival, no matter rich or poor, who doesn't want to drink a glass of safe drinking water? Especially today when water pollution is becoming more and more serious and threatening human life and safety, a glass of safe drinking water is undoubtedly the dream of many people.

Some excellent water purification technologies on the market, such as reverse osmosis membranes, can also achieve the effect of filtering water, but the amount of wastewater can reach two-thirds, causing serious waste of water resources and being very uneconomical to use. Currently, the wastewater ratio of water purification equipment on the market is not low.

And now, they have ultrafiltration purification membranes!

The amount of wastewater is less than one thousandth, and it is basically composed of pollutants, and the wastewater ratio is infinitely close to zero. The filtered water molecules are fast and clean, and the preparation value is not very expensive. If a water purifier equipped with such a purification membrane is released, it will definitely cause a sensation and rush around the world.

Even Ruan Chengxu, who has a broader vision, has thought of a bigger area, seawater filtration. By using this as a seawater filter, China will no longer worry about water depletion, and the water shortage in the west will be solved perfectly.

Wu Tong, this is a golden hen that lays golden eggs, and it is even a treasure with great economic and strategic value.

"The ultrafiltration membrane is temporarily successful, but we still have a key point that needs to be solved!" Compared to Ruan Chengxu's excitement, Wu Tong seemed calm. After all, she had predicted such a result, and now she just achieved it.

She was also very happy that her prediction had come true, but she was more concerned about another problem than excitement. Wu Tong glanced at the slightly turbid liquid in the cup and said, "How to solve this part of the pollutants is the top priority!"

After all, the heavy metal residues in it, like the tiny amount in front of them, seem harmless. However, large-scale use, the accumulation of so many concentrated pollutants, is still a major hazard. If things go wrong, they will not create miracles, but become the sinners who aggravate environmental pollution.

When it comes to the issue of pollutant treatment, Ruan Chengxu couldn't help but fall silent from his excited state.

If pollutants were so easy to solve, the world's pollution problem would not be getting worse. So far, they do not have an effective pollution control method, which is a headache for the world.

Without a treatment solution, such an excellent ultrafiltration purification membrane cannot be promoted and used? Isn't that a pity?

Or, does Wu Tong have a solution? Ruan Chengxu looked at Wu Tong expectantly. If there was anyone who could create a miracle, in Ruan Chengxu's mind, it must be Wu Tong.

When Wu Tong developed and manufactured the ultrafiltration purification membrane, did he foresee the current situation?

"Brother Xu, you think too highly of me. I only have some ideas for the specific plan now, but it is not yet complete. I still need time to perfect it. Let's collect these experimental data first, and I will continue to study and deduce!" Wu Tong laughed. She is not a treasure bag that can have everything she wants. However, facing this problem, she is not so difficult that she cannot touch it.

If it is a difficult problem, there will be a solution. We just need to find the direction of the solution.

As for the solution to organic and inorganic pollutants, Wu Tong thought of N18, which has a strong decomposition ability. This part is no longer a problem for her. After the distinction is clear, the most important issue to be solved is actually what she has always been thinking about, heavy metal pollution.

These heavy metals are harmful to the human body if they are in excess.

However, they are also indispensable metal resources for modern society, and many of them are even scarce resources. How can we extract these heavy metals so that they no longer become harmful pollutants but are transformed into effective resources for recycling?

After collecting the data, Wu Tong returned to the office and fell into deep thought. In his mind, various speculations and information about pollution treatment were flying around.

Wu Tong even had a wild idea and thought of the virtual items in the novels she had read before. This was a plant creation novel she had read in her previous life, which said that the protagonist had refined a special seed.

When this special seed is planted in water, it will naturally absorb and filter heavy metals in the water as it grows and blooms into lotus flowers of different colors. These lotus petals of different colors are made up of the metal substances they absorb.

There are also science fiction ones, such as the magical polymer smart filter, which can intelligently filter harmful substances and restore the water to a clean and pollution-free state.

···Humans have unlimited imagination. Although there is no theoretical basis, it is often just a joke. However, this is also the beautiful idea of ​​many people for purifying the environment.

Wu Tong now also wants to design a material, or a set of process plans, to achieve the effect similar to that of the special plant seeds imagined by the author, which can effectively extract and separate pollutants in polluted water, and can be classified and processed to transform them into effective resources.

After several deductions, various ideas collided in my mind. After the proof of the Goldbach conjecture, the energy efficiency was further improved. The absolute deduction, absolute direction, and sublimated absolute deduction were combined and operated at full capacity.

A vague direction of progress appeared in Wu Tong's mind. She picked up a pen and wrote the four words "restore" and "absorb" on the draft paper at hand.

With these two indicative directions, Wu Tong began to deduce how to reduce and what substances can react with all or most metals?

Acid? Reacts with acids to form various sulfuric acid compounds? Oxygen? Reacts with oxygen to form various oxides? Partial salts?

Adsorption? What kind of adsorption capacity is the most effective? Graphite? This is a mineral composed of carbon elements. It has good electrical conductivity and can quickly adsorb precious metals such as gold and silver under certain conditions.

Clay? The surface charge has a special interest, and through the adsorption mechanism, it can quickly absorb precious metals such as gold and silver.

Activated carbon? Its special pore structure and surface charge can also allow it to quickly adsorb precious metals.

However, the absorption efficiency of these fast gold-absorbing materials is not stable and is affected by many factors. They do not have the energy efficiency to completely absorb metal pollutants. Moreover, if they are combined with other substances after the previous reduction reaction, these substances are likely to lose their effectiveness.

Speaking of adsorption, there is another thing that comes to mind first.

Magnets? They can attract iron, cobalt, nickel and their alloys because the internal atomic structures of these materials are quite special and they have magnetic moments themselves!
