"With such a fast filtration speed, this can never be a nanofiltration membrane!"

Bernice shouted with a bit of desperation.

The smaller the pore size, the smaller the particles of the substance that can be filtered, and at the same time, under a certain water pressure, the permeation rate of the water will be reduced accordingly. According to theoretical calculations, the permeation flux of nanofiltration membranes can only reach a maximum of 2.5, and this is only a theoretical limit, which cannot be achieved in practice. The permeation flux of this filter membrane provided by Daqin Group is at least above 20, which is completely unscientific!

Bernice is a technical person, and of course he can also think that the Chinese are likely to have mastered a completely different filtration principle, so that they can greatly improve the filtration efficiency under the condition of taking into account the filtration effect. However, now he has no way out, he can't admit that his skills are inferior, he can only pour some dirty water on the opponent first, and then hope that the opponent will make some mistakes, and then use these mistakes to completely negate the opponent's products.

Unaffected by Bernice, the staff saw that the membrane was already working, so they took samples to check the quality of the filtered water.

"Surfactant, 1.3 ......"

"Oil particles, 0.4 ......"

"Salt, Qualified ......"

One by one, the results were reported one after another, and everyone present fell silent, and everyone invariably turned their eyes to Bernice, with some indescribable feelings in their eyes.

Daqin Group's filter membrane, in terms of filtration quality, is indeed slightly inferior to Warren Group, but it is still within the qualified range. In terms of the self-purification capacity of the sea, increasing the concentration of some chemical residues in wastewater by a few parts per million will have no ecological consequences at all. The filtration efficiency of Daqin Group's filter membrane is hundreds of times that of Warren Group. This is crucial.

"Gentlemen, what do you think of the test results?" Henlock was the first to break the silence, he was the Minister of Ecology and the person in charge of the entire clean-up project, and the final decision was for him to make. In fact, after watching this test, he already understands how to choose. But he still has to ask everyone's opinions first, so as not to criticize him from the Warren Group.

"I think the super filter membranes provided by China are perfect." Frandin preemptively said. He was most pleased with such a test result except for a few people from Daqin Group, not only because Daqin Group's filter membrane solved the problem of oil pollution cleaning, but also because they made the proud Europeans stumble. As a rich man in the Middle East, Flandin can feel all kinds of disdain for him by Europeans, and this time he can finally borrow the hand of the Chinese to give himself a bad breath.

"If the performance of the super filter membrane can be stabilized, I think it will be of great help to clean up the oil stain this time." In a more conservative way, Gemmer expressed his attitude.

Besborough turned to Qin Hai and asked, "Mr. Qin." How long do your super filter membranes last? ”

"If it's dealing with ordinary oil stains, it's about five days." Xia Yangjie answered this question for Qin Hai.

"It's only been five days?" As if he had grasped some life-saving straw, Claudon shouted triumphantly, "Our filter membranes have a lifespan of 8 to 12 weeks. ”

"It's not surprising." Qin Hai glanced at Claudon and said lightly.

"What's not strange?" Claudon asked in confusion, but before he could finish his words, he suddenly remembered something, and his face suddenly swollen red.

Isn't that strange? The filtration efficiency of other people's filter membranes is 100 times that of yours, although the service life is shorter. But the amount of sewage filtered is far more than yours. The scrapping of the filter membrane is often not due to damage, but because the filtered residue adheres to the surface of the filter membrane, causing the filter membrane to lose its filtration capacity, and the amount of residue is obviously directly related to the amount of sewage filtered.

"So, one more question, what is the unit price of your filter membrane?" Besboro asked in as calm a tone as possible. He also knew that the big picture was decided. His previous disdain for Qin Hai has become a laughing stock in front of the real results, and all he can do now is to try to downplay this matter and maintain an image of a "fair" expert.

"The selling price for this membrane is $70 per square meter. If the purchase quantity exceeds 100,000 square meters, it can be reduced to 60 US dollars. Xia Yangjie replied.

"What is the price of the Warren Group's filter membranes?" Besborough asked, turning his head back to Bernice.

"$20 per square meter." Bernice replied in a frustrated tone that Warren's $20 per square meter price was not at all advantageous compared to Daqin's $70 per square meter, given the difference in the amount of wastewater that the two membranes could treat.

Filtration efficiency is not good, durability is not good, price is not competitive, in this competition, Warren Group can be said to be a complete failure.

Why did we come to Le Havre? Bernice's heart kept blaming himself. Thinking that the person who informed them of the news was Gemmer, Bernice couldn't help but feel a little resentful towards Gemmer, but when he thought about it, Gemmer didn't ask them to come forward, but just told them that there was such a thing. It is clear that the Warren Group underestimated the technical level of the Chinese, so they ran all the way to Le Havre to wait for others to slap in the face.

Besborough pulled Henlock and several other experts aside and whispered, and when Henlock appeared in front of Qin Hai again, the smile on his face was already very kind.

"Mr. Qin, in the name of the French Ministry of Ecology, I formally propose my intention to cooperate with your company. We hope that your company will be able to provide us with 200,000 square meters of super filtration membranes for beach and offshore oil treatment in the next month, and I wonder if you can provide these products. Henlock said.

"However, we will organize production immediately to ensure that it does not affect your oil cleanup work." Qin Hai replied solemnly.

"Okay, I hope we have a good time working together." Henlock stretched out his hand to Qin Hai and said.

Qin Hai smiled and shook Henlock's hand and responded, "Happy cooperation!" ”

Besborough also stepped forward and said with a smile: "Mr. Qin, you have done a very great thing, this amazing super filter membrane you produce will completely change the mode of offshore oil pollution treatment." I hope you will be able to scale up the production of filtration membranes, because there will be many places in the world waiting to use your products. ”

"Thank you Mr. Besborough for your compliment, and I hope Mr. Besborough can do more publicity for us, so that our products can better serve the protection of the world's environment." Qin Hai said politely to Besborough, as if he had completely forgotten the discord that the two had before.

A deal was thus finalized in a harmonious atmosphere, and Henlock, Flandin, Besborough and others all gathered around Qin Hai, chatting happily and easily. They actually did not have any principled conflict with Qin Hai, Qin Hai's products could help them solve problems, and they naturally accepted this young and enviable Chinese.

As for Bernice and Claudon, they could not stay still in this situation, and they quietly left the real field with black faces.

That evening, Flandin once again held a grand banquet to entertain all the officials and experts involved in the oil clean-up work, among which the guest of honor was naturally Qin Hai and several other Chinese. At the banquet, except for a round of wine to everyone at the beginning, Flandin spent the rest of the time standing with Qin Hai, and the two of them talked in English, talking and laughing.

"Mr. Qin, you saved my company, you are my best friend." Flandin didn't know how many times he said this to Qin Hai.

"Prince Flandin, you are so polite, it is our honor that our products can solve some difficulties for the prince." Qin Hai said with a smile.

Flandin patted Qin Hai on the shoulder and said, "No, no, Mr. Qin, you don't know how important this matter is to me, if it weren't for your super filter membrane, I'm afraid I would have gone bankrupt." Mr. Qin, as a friend, I am willing to be able to do something to repay your help, do you have anything you need me to serve? ”

"Like...... Nothing, right? Qin Hai said embarrassedly. A prince of other people, crying and shouting that he had to do something to repay himself, but he couldn't think of anything that needed the other party's help, which seemed to be a bit faceless.

Flandin was also obviously a little unable to get off the stage, and he said, "Aren't you willing to give me a chance?" ”

"Hmm...... Let me think about it. Qin Hai held the wine glass and began to think contemplatively, "Your Royal Highness the Prince, in addition to the treatment of chemical sewage, the filter membrane we produce can also be used for seawater desalination, I wonder if there is a demand for this in your country?" ”

"Desalination? This is so important to us! "You know, Saudi Arabia is a water-scarce country, and desalination is of strategic importance to us. Our current desalination plants are all built by European companies, and if you can provide desalination technology that is no less than European, I can get the government to cooperate with you in this field. ”

"Our technology is not inferior to the Europeans at all, and as we have seen today, we are in some ways stronger than the Europeans." Qin Hai said confidently.

"Okay, then we'll make up our minds. As soon as I have dealt with the oil spill, I will return to my country to contact the matter, and I look forward to seeing you again in Riyadh. Flandin said.

Xia Yangjie, who was standing not far away watching them talk, sighed and whispered to Yu Lihong beside him: "I'm really convinced, just after a while, Mr. Qin has negotiated a big business again." If you can take Saudi Arabia's desalination project, it will be at least a billion dollars of big projects. ”

"Haha, I've long been convinced, follow Mr. Qin, we never have to worry about being idle." Yu Lihong raised his wine glass with a smile and said to Xia Yangjie. (To be continued......)
