The Warren group soon came to Le Havre. After hearing the news that a Chinese company claimed to be able to provide super filtration membranes, the long-established chemical group naturally couldn't sit still. In the case of Europe, a Chinese company is also needed to provide technology, which is unacceptable to the Warren Group. Traditionally, it has always been the case that Asian affairs are not settled on their own, and they go to Europe to ask for help, and there is no reason for the other way around.

Warren Group is one of the world's top three large chemical groups, with subsidiaries and production bases in dozens of countries on five continents, with an annual output value of nearly 100 billion US dollars and tens of thousands of chemical technology patents. Oil filtration membranes are one of the traditional products of the Warren Group, which occupies almost half of the global market share in this field.

How could such a company, which had always been over-the-top, suddenly hear that someone can offer a better product than them, and claim that the filtration efficiency is 100 times higher. After receiving the call from Gmer, the Membrane Division of the Warren Group immediately sent two technical experts to Le Havre with 1,000 square meters of the best membrane.

"We wondered, which company claims to be able to offer super filtration membranes?"

As soon as Bernice, a technical expert from the Warren Group, arrived in Le Havre, he asked Willitz, Germer's assistant, in a menacing manner. Because this news was informed by Gemmer to the Warren group, Bernice regarded Gemer as an enemy.

"It's a Chinese company called Daqin Industrial Group." Wilitz replied.

"Daqin Industrial Group?" Bernice pouted, "I've never heard of such a company, and Professor Gemer is also a well-known scholar in the industry, how can he casually believe the claims of a Chinese company?" ”

"Actually, we don't believe in it, we just want to have more possibilities to solve the problem. Professor Gemer also contacted your company because he trusted your company's technical prowess. If a Chinese company can produce this super filter membrane. Then there's no reason why Warren can't make a better product. "Willitz didn't give Bernice a nail in the way.

"Uh...... That's natural, we're the most technologically advanced ...... in the industry," Bernice was speechless, and he suddenly realized that he had come too recklessly, if the Chinese company could really provide a super filter membrane, even if it was not 100 times more efficient than Warren's counterpart, but only 10 times as efficient. Even several times, the face of the Warren company will be very ugly. As Willitz said, there's no reason why Warren can't do something better.

"Where is the Chinese you are talking about, we want to meet him." Bernice said.

"Okay, I'll get in touch with him." Willitz said.

Le Havre is not big, so it is not difficult to find Qin Hai. When Willitz took Bernice and his companion Crowdon to meet Qin Hai, Qin Hai was standing on the beach with Frantin, Dredge, and others discussing how to wash off the oil. Qin Hai gestured with his hand to explain where to build a water-retaining fence on the beach with a super filter membrane, and then use seawater to wash the beach.

"After the oil stain has been treated with a strong surfactant. The oil stain breaks down into macromolecular particles with a molecular weight of between 300 and 800 and loses its viscosity. When washed with seawater, these macromolecules separate from the sand particles and flow into the seawater. We use a filter membrane to separate the seawater from the macromolecular particles, and the clean seawater can flow into the sea, while the toxic macromolecular particles will remain on the filter membrane. We only need to change the membrane once a day. Qin Hai said to Frandin.

"How long will it take to process the entire Le Havre beach according to this plan?" Frandin asked.

"If there were enough pumps and construction machinery to lay the filter membranes, I estimate that it would only take about 20 days to complete." Qin Hai said.

"Great. As a result, our compensation payments can be reduced to one-twentieth of the same, which can save billions of dollars. Frandin said excitedly.

"I'm sorry. Your Royal Highness, I think that the scene described by this gentleman is only an imagination, and it is impossible to do it in practice. Bernice stepped forward and interrupted Flandin very rudely.

"Who are you?" Frandine turned his head to look at Bernice, and asked with a look of displeasure on his face.

"I'm Bernice, a senior technician in the Membrane Division at Warren Group, and this is my colleague Claudon. We are here to provide you with filtration membrane services. Bernice said arrogantly.

"The Warren Group?" Flandin nodded, he was in the oil business, and it was impossible not to know about a large chemical company like the Warren Group. He asked, "You mean, you're able to provide a membrane for this oil treatment?" ”

"Of course, we are the world's most professional manufacturer of filtration membranes. It can produce various types of microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes to meet the various needs of customers. Anything you can think of, we can do it. ”

Hearing Bernice's lively words, Flandin couldn't help but feel a little moved, he turned his head to Qin Hai and asked, "Mr. Qin, do you know anything about the situation in Warren Company?" ”

"Got it." Qin Haidao, "Warren Group has rich experience in the manufacture of filter membranes, and its products are well-known all over the world. ”

"Uh-huh." Bernice shrugged his shoulders triumphantly, indicating that he accepted Qin Hai's praise.

"However, as far as the oil pollution treatment work is concerned, the existing products of the Warren Group may not be able to meet our needs." Qin Hai added lightly.

Bernice's face changed: "What do you mean?" If our products can't meet the requirements, can your products meet the requirements? ”

"You're right." Qin Hai smiled, "Can you provide nanofiltration membranes with a permeability of more than 20 cubic meters per square meter per day?" ”

"20 cubic meters?" Bernice was stunned for a moment, and then sneered: "Sir, are you talking in a dream?" It is impossible for nanofiltration membranes to achieve such permeate fluxes, so I guess you are confusing microfiltration with nanofiltration, right? ”

According to the different pore sizes, the filter membrane can be divided into different levels such as microfiltration, ultrafiltration, nanofiltration, reverse osmosis, etc., and the corresponding separated substances are getting smaller and smaller. Microfiltration is mainly aimed at pellets with a particle size greater than 0.1 microns, such as bacteria, yeast, etc.; Ultrafiltration targets macromolecules with molecular weights greater than 500 and fine colloidal particles, such as proteins, enzymes, etc.; Nanofiltration is aimed at small molecules with a molecular weight of less than 500, including antibiotics, synthetic drugs, dyes, etc.; Reverse osmosis membranes are capable of filtering out inorganic salts such as sodium chloride.

The smaller the pore size of the filter membrane, the slower the speed at which water flows, and the nanofiltration membrane produced by the Warren Group has a maximum of 0.2 cubic meters of permeability per square meter per day, so when Qin Hai said the figure of 20 cubic meters, Bernice's first reaction was to not believe it at all.

Bernice's reaction did not exceed Qin Hai's expectations, and anyone who heard a technology that was a hundred times stronger than his own highest level would obviously not be able to believe it, especially since behind Bernice was the Warren Group with strong technical strength.

"Sir, I'm talking about nanofiltration membranes, and you know that very well. Our nanofiltration membrane is called Super Nanofiltration Membrane because it can increase the permeation flux of water by more than 100 times without sacrificing filtration effectiveness. Only such a filter membrane can meet the needs of cleaning oil stains this time. Qin Hai said in a confident tone.

"How did you do that?" Bernice asked.

Qin Hai looked at the other party with a look of pity, and it took a long time before he sighed and said, "Sir, do you think it's appropriate to inquire about the core technical secrets of a peer like this?" ”

"We're not going to spy on your core technology, we just don't believe in a filter like Zài. We have theoretically calculated that the theoretical maximum permeation flux of nanofiltration membranes is 2.5 cubic meters, and in fact no company has been able to achieve such a theoretical value. As for the permeation flux of 20 cubic meters, this is contrary to the principle of fluid science,...... If you know the model algorithm. Videodon commented.

"Maybe your model is right, but we do produce products that achieve this level of permeability. As for the rationale, I think you'll soon see it from the application published by the European Patent Office. Qin Hai said with a smile.

The super filter membrane was originally developed by Pujiang Haijie Company under the inspiration of Qin Hai, how could Qin Hai not understand the technical details. Qin Hai had also seen the computational model that Claudon was talking about, and knew that the theoretical calculation results he said were well-founded. The key problem is that the super filter membrane produced by Jintang Petrochemical has been structurally improved to bypass the obstacle that Croden said.

The technical mystery of this is also very simple to say. Traditional filter membranes are flat membranes, one square meter is one square meter, and there is no room for it. The super filter membrane proposed by Qin Hai is to roll the flat membrane into a tube, and there are countless thin tubes on the same square cross-section, and the area of each tube is equivalent to hundreds or even thousands of times that of one square meter.

In other words, in fact, the so-called super filter membrane is designed to be a hundred square meters of filter membrane through the guò structure on one square meter of material, and its permeability is of course equivalent to hundreds of times that of the traditional flat membrane.

The thickness of the filter membrane is generally less than 1 micron, even if it is rolled into a tube and then superimposed, that is, the thickness of one or two millimeters, it does not affect the use at all. This material, known as hollow fiber membranes, is an upgrade of traditional membranes, which Bernice and Claudon have not heard of, and it is quite normal.

This special structural design has been filed as an invention of Haijie and filed patent applications with several major patent institutions around the world. Bernice and the others will see the relevant information sooner or later, but now Qin Hai is too lazy to explain this to them, he is still waiting to see the other party's jokes.

"No, I don't believe in such a filter as Zài, you must have done something somewhere, I'm going to expose your deception!" Bernice exclaimed, red-faced. (To be continued......)
