Zhou Yu thought of Feng Yunde's smug expression when he first arrived at the Materials Research Institute.

He only developed the technology for waste disposal, which was a bit too much, because he still had a better technology in his hands.

"Don't sell it, what kind of technology has been developed," Zhou Yu asked directly.

Feng Yun dragged Zhou Yu to the laboratory next door, and he introduced as he walked: "In order to study and treat complex metal ions in wastewater, our research institute has developed a membrane material with the ability to actively select certain ions.

We have developed this kind of membrane, and have not given up in-depth research and development of it, and now we have developed a membrane that can actively select water molecules, I named it water permeability membrane, and the technology based on water permeability membrane is called water purification technology. ”

Feng Yunde gave Zhou Yu a detailed introduction to the characteristics of water purification technology.

"The fact that you have been able to develop a membrane material with this effect is really important research, and the prospect of water storage technology is very broad." Zhou Yu said heartily approving.

He knows that there are many application scenarios for this kind of technology, and there are two main applications.

The first important application scenario is the regeneration of urban domestic sewage, which uses about 600 million cubic meters of water annually in a large city like Yanjing, which is a very large amount of water consumption.

The distribution of water resources in China is extremely uneven, and the north is a water-scarce area, and if 50% of these 600 million cubic meters of water resources can enter the drinking water market, it can solve a huge problem.

In the past, domestic sewage was treated into reclaimed water, which could only be used for industrial water such as watering green spaces and car washes, and the water treated by water purification technology was completely drinkable.

The second important application scenario is desalination.

Only 3% of the earth's water resources are freshwater, and 77% of such scarce freshwater resources are stored in glaciers in the Arctic and Antarctic and high mountains.

Freshwater resources available to humans are very scarce, and coupled with the expansion of the human population, the earth's water resources are now very scarce.

If Feng Yunde's research on water permeable membrane materials can be used to easily produce freshwater resources, it will not only solve the problem of water scarcity.

It can even contribute to the birth of maritime cities, which are now fully realized through technology and floating offshore cities.

The most difficult part of the sea can be transported, and the most difficult thing is to talk about the acquisition of water.

Feng Yunde led Zhou Yu to a transparent glass jar.

This glass jar is 3 meters in diameter and about 5 meters in height.

The inside of the glass jar bends and folds many small pipes the thickness of an arm.

The yellow sewage passes through this glass jar, and there is clear clear water flowing out of the bottom outlet of the glass jar.

Feng Yunde said proudly: "Mr. Zhou, this is the water purification technology we are studying, it obtains absolutely pure water, which is purer than distilled water, and there are no impurities in it.

There is no need to buy distilled water from the institute, it is sent directly from us. ”

Zhou Yu pointed to the color of the water in the glass jar, frowned and asked, "Why is the water here this color, it makes people feel bad when they look at it."

"This is our company's domestic sewage, and the main sources are canteens and staff dormitories.

There is sewage from the sewer and sewage from the canteen to wash the dishes and chopsticks, and the sewage is triple filtered, and there are some fine impurities in it.

However, our company's water purification technology is very advanced, and the water permeable membrane can only choose water molecules to pass through, not to mention bacteria and viruses, and even oxygen molecules can't pass through. ”

After Feng Yunde finished introducing, he picked up the disposable paper cup next to him, unscrewed the faucet at the bottom of the glass jar, and took a glass of water.

He directly leaned his neck and drank it clean, and said with a smile: "I have just introduced that after our treatment, the water is very clean and can be drunk directly."

Feng Yunde took a glass of water and handed it to Zhou Yu and said, "Mr. Zhou, you can taste our treated water."

Zhou Yu looked at the yellow water in the glass jar and thought that this water was the water for flushing the toilet.

He felt sick in his heart, frowned and hurriedly waved his hand and said, "I still don't drink this water."

"Mr. Zhou, you are too hypocritical, the water in the glass jar looks very buried, and it is indeed sewage, but after we treat it, even people who are obsessed with cleanliness can't find fault." Feng Yunde continued to persuade.

"That's because people with cleanliness habits don't see what the water looks like before treatment, this kind of extensive treatment is absolutely not good, and people who know about it will never drink a sip of water treated like this.

You know a lot about technology, but you don't know about human nature.

This equipment had to be supplemented with ancillary equipment, and I saw in the documentary that the wastewater treatment technology in Huaxia is already very advanced, and after 18 filtration stages, the reclaimed water has become clear and transparent.

You use reclaimed water for water purification to further remove impurities from the water, which is not the case for the human senses. ”

Zhou Yu immediately put forward his opinion.

"Hey!" Feng Yunde sighed and said, "Mr. Zhou, my work has ended, the purification technology is basically formed, and the water purification technology and equipment manufacturer is responsible for these improvements you mentioned."

I handed over a full set of water purification technology to Yuan Keqing and them, and the equipment was produced by them, and I want to inform them of your ideas. ”

"I don't need to contact Yuan Keqing, let Xinghuo Precision Manufacturing Company specialize in machinery manufacturing, and I plan to set up a new company to manufacture new materials and products.

You passed on the water purification technology to me, and I arranged the rest, and you have done a lot of work this time.

The water purification technology project will enjoy the project revenue sharing in accordance with the company's regulations, and the relevant scientific research personnel will also be promoted. ”

Zhou Yu obtained the water purification technology, and he left the Institute of Materials.

In the process of returning to Longkou Building, he chose which new company would be responsible for the production of water permeable membranes, and which middle-level leader would be used as the general manager of the new company.

For the sake of convenience, Xinghuo Technology has set up many subsidiaries that may be used in the future, and these companies are now shell companies.

As long as Spark Technology sends competent people and injects capital into them, these dormant companies will be launched.

When Zhou Yu returned to the office, he had already figured out which new company to choose.

He immediately instructed the financial manager Lu Bing to inject 50 million yuan into Xinghuo Materials Company, and Jiang Weiwei, the manager of the human resources department, to complete the employees of Xinghuo Materials Company.

He called Gou Fugui, the middle-level leader of the sales department, and handed over the business of forming Xinghuo Materials Company to him.

After Zhou Yu went out in Gou Fugui, he began to improve the water purification technology, and the core was still the water permeability membrane.

It's just that he didn't choose the water permeable membrane pipe from his arm like Feng Yunde.

Instead, the water permeable membrane is made into an ultra-fine tube with a diameter of 10 microns, so that the contact area between it and the water surface is larger.

He set the water resources treated by the water permeable membrane equipment to be reclaimed water that has undergone multiple filtration and is no longer free of solid impurities.

Zhou Yu just asked Xinghuo Materials Company to produce water permeable membrane equipment.

He is not ready to let Xinghuo Technology personally produce pure water and be a tap water supplier.

The water sector is too complex, with political risks involved.

In the early days of China, water services were sold to foreign companies and contracted to private companies.

Now the state has discovered that this kind of industry, which naturally has a monopoly, must not be given to private management, but must be controlled by the state.

The country has been constantly reorganizing the tap water market through various means, and Xinghuo Technology can easily make money, so why bother to wade into this troubled water.
