"Our ultrafiltration membrane is amazing, it only reduces the wastewater volume by one thousandth!" The ultrafiltration membrane is worthy of its name, 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 water? Especially today when water pollution is becoming more and more serious and threatening human life and safety, a glass of safe water is undoubtedly a dream of many people.
Some water purification technologies on the market, such as reverse osmosis membranes, can also achieve the desired effect of filtering water, but the amount of wastewater can reach two-thirds, resulting in serious waste of water resources and making it 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!
Less than one thousandth of the wastewater is essentially contaminants, bringing the wastewater ratio to near zero. The filtered water molecules are clean and efficient, and the production cost is relatively inexpensive. A water purifier equipped with this membrane would undoubtedly cause a global sensation and attract significant attention if it were released.
Even Ruan Chengxu, who has a broader vision, has thought of a larger area, seawater filtration. By using this as a seawater filter, China will no longer suffer from water depletion, and the water shortage in the west will be able to get a perfect solution.
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 a temporary success, but we still have a key issue that needs to be addressed!" Compared to Ruan Chengxu's excitement, Wu Tong seemed calm and composed. After all, she had already predicted such an outcome; now she had simply achieved it.
She was delighted that her prediction had come true, but she was more concerned about another issue than excitement. Wu Tong glanced at the slightly cloudy liquid and said, "How can we resolve this contamination issue? The most important thing is!"
After all, the numerous heavy metal residues in this wastewater, like the tiny speck before them, appear harmless. However, large-scale use, where so many concentrated pollutants accumulate, still poses a significant hazard. If things go wrong, they could become the perpetrators of worsening environmental pollution, rather than creating a miracle.
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 way to control pollution, which is a headache for the world.
Without a treatment solution, wouldn't it be a shame if such an excellent ultrafiltration membrane couldn't be promoted and used?
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 would have to 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 a specific plan right now, but it's not yet complete. I need more time to perfect it. Let's collect the experimental data first, and then I'll continue to research and deduce it!" Wu Tong laughed. She wasn't a jack of all trades, but she wasn't so naive as to be unable to handle this problem.
If it is a difficult problem, there will be a solution. We just need to find the direction of the solution.
Wu Tong came up with the highly decomposing N18 for organic and inorganic pollutants. This issue was no longer a concern for her. With this distinction clear, the most pressing issue to address was the one she had been considering: heavy metal pollution.
These heavy metals are harmful to the human body if consumed in excess.
However, for modern society, they are also indispensable metal resources, and many are even scarce resources. How can we extract these heavy metals so that they no longer become harmful pollutants and are transformed into effective resources for recycling?
After collecting the data and returning to his office, Wu Tong fell into deep thought. Various hypotheses and information he had come across regarding pollution treatment raced through his mind.
Wu Tong even had a wild thought, thinking of a virtual item from a novel she'd read before. This was a novel about plant creation from her past life, where 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 to grow and bloom 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 directions, such as the magical polymer smart filter, which can intelligently filter out harmful substances and restore the water to a clean and pollution-free state.
Human imagination is limitless. Although often lacking theoretical basis, it often makes people laugh. 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 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. Absolute deduction, absolute direction combined with sublimated absolute deduction, worked 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 it and what substance 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? Some salts?
Adsorption? What kind of adsorption capacity is most effective? Graphite? This is a mineral composed of carbon. It has good electrical conductivity and can quickly adsorb precious metals such as gold and silver under certain conditions.
Clay? Its 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 also allow it to quickly adsorb precious metals.
However, the absorption efficiency of these fast-absorbing gold materials is unstable and affected by many factors, and they are not efficient enough to completely absorb metal pollutants. Moreover, if they undergo the previous reduction reaction and combine with other substances, these substances are likely to lose their effectiveness.
Speaking of adsorption, there is one thing that comes to mind first.
Magnets? They can attract iron, cobalt, nickel, and their alloys because the atomic structures of these materials are special and they have magnetic moments!
