There is a shortage of fresh water on the earth, so why do you need to use fresh water for bathing a

Finally, let's talk about why the mainland does not use seawater to flush toilets, first of all, many places in the mainland do not have sea, and some coastal areas are basically not short of fresh water resources. If we want to learn how to use seawater in Hong Kong, we will have to lay new pipelines, and such a cost investment is obviously unnecessary. So I think the reason why the coastal areas of the mainland do not use seawater to flush toilets is not only the increase in costs, but more importantly, there is no need for this, and the mainland has not reached such a lack of fresh water resources.

One is because of convenience, after all, not all people live by the sea. Second, because of its practicality, the water used to flush the toilet can be reused after a series of transformations. Third, because of the price, the cost of transporting seawater to the mainland is too high.

Fourth, because of the function, the salt content of seawater is high, and it should be rinsed with fresh water after bathing.

One of the ways to save water resources in the city is to recycle rainwater, and part of the sewage purification for the use of 'reclaimed water', that is, this feasible method has also been hard to develop for many years, there are still many difficulties in the implementation, drinking water, reclaimed water two sets of water sources, and the implementation of urban recycling, purification is also costly, and the amount of transformation is very large.

Hong Kong can use seawater to flush toilets, and the mainland still uses fresh water, whether it is a technical problem or a cost problem, I think some of them are a bit nonsensical to ask. I think Hong Kong has to use seawater to flush toilets, Hong Kong itself is a place with a very lack of fresh water resources, because there is no fresh water, so we can only find a way to use seawater to flush toilets, and many places in the mainland do not have a special shortage of fresh water, not to mention that many places in the mainland do not have sea, so this problem is really a bit nonsensical. In some coastal areas of the mainland, there is no problem in terms of technology, mainly because the cost of drinking seawater to flush toilets will increase.

Take a bath and try to wash it with salt water? Flushing toilets is not good, it is highly corrosive and not good for sewers, and fresh water can be recycled.

The main problem should be the cost, although fresh water is very scarce now, but if you use other types of water instead of fresh water to flush the toilet, it is more expensive, so you need to use fresh water to flush the toilet!

Do you want to transport seawater to the mainland to flush toilets? The tofu has been turned into gold!

Seawater is extremely corrosive, and if it is used to flush the toilet, the toilet at home may not last long.

You're right! It can be studied and studied, and if successful, a lot of fresh water can be saved.

In fact, you can do without drinking water, if you use seawater, it may cause damage to the skin.

There is a lot of salt in the seawater, and the pipes will corrode and rot after a long period of use.

If it is dried with salt water, it will crystallize later.

At present, China's technology and the world's technology level are about the same as that of seawater into fresh water, but due to the high cost of operation, it has not yet been implemented, and if it is implemented, the price of water will definitely rise, and since 2015, the country has set off sponge cities, which has greatly reduced the pressure on municipal water supply.

So what kind of water do you say you should use to take a bath and flush the toilet?

That's because you only have one fresh water route in your home and no seawater waterway, or any other waterway. After all, the house only gives you a set of waterways, you don't use fresh water to flush the toilet, do you use seawater? Moreover, it is not easy to purify seawater for daily use, not to mention the high cost, the technical requirements are also high, and it is even more difficult to popularize the use.
