Jiang Yichen stood in the bathroom, lifted the sewage bucket used to clean the window, and poured it into the dun cloth pool at an angle.

Who knew this tilt, but suddenly found something strange.

I saw that the bucket was poured out of the clear and bright clean water, which was not at all the expected black and dirty liquid.

Huh, what's going on? Did you remember wrong? Jiang Yichen was quite surprised, and then stopped his hand and brought the bucket to the window for a closer look.

With the help of good light, he could see clearly, the water inside was indeed crystal clear, and the bottom of the barrel was deposited with a layer of gray-black dirt, which seemed to be very dense at the look. This shows that the water was indeed dirty before, but why did it suddenly become so clean?

Looking back at the chemistry I learned in middle school, the reason why sewage looks muddy is because there are a lot of insoluble dirt such as sediment in the water. The sediment particles, which have a large specific gravity, do not stay in the water for a long time, and as long as the water storage container is left stationary for a period of time, they will soon settle to the bottom. As a result, the water is much clearer.

However, those small impurities have become colloidal particles, the specific gravity is also light, and there is also an electric charge, which is often difficult to precipitate, and basically remains suspended in the water all the time. Therefore, in some areas with poor water quality, such as the Loess Plateau, if the static method is used to treat well water and river water, the desired effect is often not obtained.

The more common treatment method is to add alum to the water, and after the alum is dissolved in water, it undergoes chemical changes to produce a large amount of aluminum hydroxide. Aluminum hydroxide can adsorb small particles of impurities suspended in water, making them heavier and precipitate. As a result, the water becomes clear and clean.

But I didn't have the time to put any alum in this bucket, and only let it sit for about an hour. It's unbelievable that this has been achieved.

To make sure again, he removed the bucket and poured some into the basin next to him.

The water is still clear and bright, without impurities, and it looks cleaner than the tap water that has just flowed out of the faucet.

It was a strange thing, he subconsciously shook the bucket, and half of the unmelted purple ice rolled in it. There was a clattering sound, and the gray-black sediment underneath did not float up and disperse, as if it had considerable weight or stickiness.

Don't......

Jiang Yichen's mind kept thinking, and a thought quickly jumped out.

To confirm this idea, he did not hesitate to stretch out his finger, dip it in the basin, and put it in his mouth.

A familiar salty taste immediately poured into your mouth. Phew, he turned his head and spit it out.

Sure enough, the reason is in this purple ice. He was sure in his heart.

This salty and astringent taste is so special that you can't forget it after tasting it. Even though the taste is much lighter than the original solution due to dilution, it can still be clearly distinguished.

Could it be that this purple ice is similar to alum? Purifying water?

No, the water purified by alum is not very healthy and has a slight odor, but it is generally acceptable. Especially in the case of water shortage, there is no problem with drinking it directly. But this purple ice is different, and it has a salty taste no matter what. Even if it is diluted, it is reluctant to drink it.

So, where is its value and role? You know, some time ago, I judged it to be close to waste. He stood still, frowning and thinking, but for a moment he couldn't find what to do.

Forget it, this kind of thing can't be rushed, let's explore it slowly.

But today, I finally saw the other side of the purple ice, and it seems that it is not far from the real unraveling of the mystery.

In order to confirm that the phenomenon in the bucket is not accidental, another test must be done.

He found another glass jar, grabbed a small handful of dirt from the pot and threw it in, poured it with water, shook it to mix, and finally broke a small piece of purple ice and threw it on the bedroom windowsill.

It's not early, and I have to hurry up and make lunch.

Thinking of this, Jiang Yichen walked quickly into the kitchen. At this time, the chicken soup had been stewed, and he removed the soup pot, washed his hands and began to cook.

It was close to twelve o'clock at noon, Jiang Guoming came back from work, and as soon as he pushed the door into the house, he praised the chicken soup for being so fragrant, which made him hungry. Then he put down his bag, rolled up his cuffs and came to the kitchen to help.

Ten minutes later, the father and son enjoyed a delicious and pleasant lunch together.

After the meal, Jiang Yichen cleaned up the kitchen and returned to his small bedroom. I couldn't wait to cast my eyes on the glass cans and bottles on the windowsill.

The experiment was successful, and after just one meal, the water in the canned bottle became clear and shiny, and of course, a layer of dirt was deposited at the bottom of the bottle, which was similar to the phenomenon of the toilet sewage bucket just now. The effect is quite neat.

He stood in front of the windowsill, his heart excited.

This fact can basically confirm his guess, it turns out that purple ice does have the effect of purifying sewage. It was a heavy discovery, and the purple ice instantly draped a halo in his eyes, and it seemed that it was no longer that useless waste.

God let him open the No. 3 Purple Ice Cave, and it was really not a joke, but it is estimated that God does not have the leisure time to do boring things.

I was burned by the stew pot today, and it was really hot, and it was worth it, otherwise I don't know how long I would be confused.

The mystery of purple ice has finally been solved, so the next key question is, what is the practical application value of this ability to purify wastewater? He looked at the can and thought about it.

Unlike alum, purple ice has a salty taste, and it was used to water plants on Yunsha Island some time ago, and its effect is similar to that of seawater, which is completely unworkable. Even if it is diluted, it is certainly not suitable for plant growth.

Since it is not suitable for the growth of plants, it is naturally impossible to purify polluted fresh water, let alone drinking grade. So what else can you do?

Could it be...... Purifying seawater?? A bright light flashed through his mind, and his thoughts suddenly became clear.

By the way, the sea water itself is salty, and the smell of purple ice is obviously no longer a problem when added to it.

Follow the vine and touch the melon, and continue to push down. Seawater purification, first of all, has very important practical significance for marine aquaculture. In the tidal flat aquaculture pond in the west of Yunsha Island, the melted white ice and green water are regularly added to it, which can play a role in nourishing and promoting the growth and development of the aquaculture sea.

However, these two types of ice water do not have the function of purifying seawater, and they are powerless to deal with the excrement of seafood in the pool. Therefore, in order to ensure the cleanliness of the breeding pond, two simple regulating valves are specially installed, and the old water in the pond is replaced by the high tide and low tide of the seawater, so as to improve the water quality. Of course, it is also a hassle to refill the space ice after each water change.

Now that there is purple ice, if it is added to the breeding pond in an appropriate amount and the dirt settles steadily to the bottom of the pond, then at least the frequency of water change and cleaning should be reduced, and the amount of manual labor will be reduced accordingly.

Well, quite a good idea indeed. However, it must be based on the premise that purple ice is harmless to marine life, and this needs to be further confirmed before it can be put into practical use.

Expanding the idea, where is the need for seawater purification in the real society? From aquariums and aquariums, to seawater aquariums in the flowers, birds, fish and insects market, as well as the transportation of fresh seafood.

There is a large underwater world in the Beicheng District of Lingjiang City, which was built a few years ago, and it is said that the facilities are very advanced, and its scale is the first in the range of several nearby provinces. However, I only often see it in advertising media during the New Year's holidays, and I haven't visited it in person.

However, it seems that these things have nothing to do with themselves for a while, so they can't just come to the door and sell purple ice as a seawater purifier.

Waiting for your own seafood restaurant to enter the real process can also come in handy. Set that aside.

Suddenly, an even bolder idea popped up.

If the effect of purple ice is very powerful, for example, a little bit can purify a large amount of seawater, so can it be used directly around Yunsha Island? In particular, it is not easy to melt and has the characteristics of slow release, which seems to be more in line with this idea.

This thought seemed a little crazy, Jiang Yichen's heart beat faster, and a layer of fine beads of sweat oozed from his head.

As we all know, China's environmental problems are becoming more and more severe, due to poor supervision, a large number of industrial and domestic wastewater is discharged into rivers and lakes without treatment, and these harmful substances finally converge to the estuary and flow into the sea. As a result, the pollution in the coastal waters is strict and the water quality is poor.

As a direct consequence of overfishing and water pollution, coastal fishery resources have been almost depleted over the years, and many fishermen have been forced to switch to tidal flat farming and cage farming along the coast. However, it is clear that no one can avoid the problem of pollution, and the quality of aquatic products cultivated in this environment can be imagined.

From another point of view, in high-end seafood restaurants, all those who advertise imported aquatic products are all expensive, far exceeding domestic goods. In addition to containing a little bit of "admiring the ocean" complex, it is also very revealing in general.

Yunsha Island is ten nautical miles away from Lingjiang Port and seven nautical miles away from the nearest land, so the water quality of the surrounding sea water is relatively better.

In terms of comparison, the sea water in the west is almost a bit yellow, and sometimes it is a little yellow and mixed according to the influence of different climates. The silver sand beach in the east is the best, and it looks very beautiful with clear blue and clear water.

Jiang Yichen once thought that the sea water near Silver Beach was already very good, but it wasn't until he saw high-definition travel videos and high-definition photos of the Maldives on the Internet that he realized that he was actually a frog at the bottom of a well. (To be continued)
