We have discussed water purifiers and purified water before, and many friends want us to talk about clean water and soft water in the whole house again, so let's talk about it today. ?

1, to know the composition of clean water in the whole house.

First of all, you have to confirm the location of your tap water pipe. The pre-filter is installed at the main valve and can only filter impurities such as sediment and rust. ?

The filtration of the central water purifier is finer than the pre-filtration, which can filter out bacteria and some heavy metals. If it is not a villa, there is no need to install a central water purifier at home. ?

The principle of water softener is ion exchange, which can remove calcium and magnesium ions from the water, but can't remove other impurities in the water. The water flowing into the kitchen is filtered and passed through the water purifier, which will save the filter element of the water purifier and prolong the service life. The purified water from the water purifier can be drunk. ?

At the same time, through the installation of pre-filter, central water purifier (optional installation), water softener and water purifier, a complete whole house water purification system is formed.

2. Do you know about water softener?

Soft water belongs to domestic water, but the hardness of water becomes lower, which protects water pipes, faucets and other wading equipment from scaling, prolongs the service life of water heaters, and makes floor heating have better heat dissipation. Make the washed clothes more fluffy and soft, and avoid leaving stains on sanitary ware and bathtub. ?

What is the price and principle of water softener?

First of all, it must be clear that the water softener must be equipped with a pre-filter screen. ?

A front filter element1000-2,000 yuan (price of home appliance store) and a water softener 1W+. Generally, it is enough to buy 1T resin for one kitchen and one bathroom. One kitchen and two bathrooms had better buy 1.5T resin, which is related to the water consumption per unit time. If it is self-heating, you should also choose a water softener with large water volume.

The principle of water softener is ion exchange, and calcium and magnesium ions in water are replaced by resin in water softener. Therefore, the core technology of water softener is resin. If the resin is broken, replacing it is basically the same as replacing it with a new machine. Thousands of pre-filters are used to protect tens of thousands of water softeners. Isn't it necessary to be expensive at once? ?

Everything's fine. The water softener has been used for 10-20 years without problems. ?

Cleaning and wastewater

The front water purifier is transparent, filtering large particles of sediment, so the filtered dirty things can be seen by the naked eye. The front water purifier needs to be cleaned regularly, including automatic cleaning and manual cleaning.

Unlike water purifiers that change filter elements regularly, water softeners help resin reset by adding salt to water regularly. The salt added in the water softener is not our edible salt, but the special salt for the water softener. When buying a water softener, the brand will give away a lot, and when it is used up, buy it from the manufacturer. The monitor of the water softener will remind you to add salt, and the frequency of adding salt is directly proportional to your living habits and water frequency. ?

Different from the waste water produced by the water purifier with pure water edge. The water softener discharges waste water in the same way as the washing machine automatically washes away the foam in the drum when rinsing. The wastewater from the water softener will also wash the inside of the machine repeatedly with clean water, taking away the impurities accumulated in the resin. There are a lot of calcium, magnesium and sodium ions in the wastewater, and this part of the water can no longer be profitable and can be directly discharged. ?

The factory setting of the water softener is that whenever you use 3 tons of soft water, it will automatically discharge 1 ton of wastewater at night. That is to say, the ratio of soft water to waste water is about 3: 1, which is related to the water quality of your home, the resin content of the water softener (1T, 1.5T mentioned above) and the water consumption of your living habits. ?

Waste water is also money.

My family of three go to work during the day, and their daily activities are concentrated in the evening, which is normal on weekends. The real water consumption in my home is 8 tons a month and 96 tons a year. The first step is 5 yuan/ton, and the annual water fee is close to 500 yuan. This is the case without a water softener. ?

If I install a water softener, my monthly living consumption will still be 8 tons, and the discharged wastewater will be nearly 3 tons. The actual total water consumption in one month is nearly 1 1 ton, and one year is 132 ton. Without water softener, it consumes more than 36 tons of water in one year, which is less than that in 200 yuan.

If you are relatively rich economically, pursue a better quality of life and feel that you consume dozens of tons of water more than a year in an affordable atmosphere, you can choose to install a water softener. In this way, your water heater and shower will not have scale, and the washed clothes will become soft, which will bring you a better life experience. ?

However, buying a water softener is different from buying an air-conditioned TV. You need to go to the appliance store to communicate with the shopping guide before renovation. They will send workers to your home to determine the actual situation and confirm whether the location and space are suitable for installation. If it can be installed, one more item can be determined in advance, and a lot of things will be saved in the later decoration, so there is no need to rework it back and forth. ?

3. Soft water, purified water and bottled water

Is soft water pure water? ▕?

Soft water is not pure water. The water filtered by the water softener is called soft water, and the water filtered by the water purifier is called pure water. Soft water is not equal to pure water. ?

The water softener can't filter out viruses, bacteria and heavy metals in the water, so you can't drink soft water. Watering the flowers with soft water will kill the fish.

The main components of scale are calcium carbonate, magnesium hydroxide and magnesium carbonate. The calcium and magnesium ions in the official water are filtered by the water softener, so there will be no scale in the soft water. ?

The white slag in boiling water is scale, and all kinds of filter kettles only filter scale. ?

People and children with lithiasis should try to avoid drinking water containing scale.

Whether there are minerals in pure water is everyone's greatest concern.

Drinking pure water leads to rickets is not credible?

Rickets is also called rickets, and its pathological mechanism is vitamin D deficiency, which is related to less sunlight exposure and has no direct causal relationship with purified water. ?

The intake of trace elements can't rely solely on water?

The function of water in human body is not to supply minerals and trace elements, so what does it matter whether water contains minerals or not? ?

The minerals and trace elements ingested by human body are mainly obtained through food (vegetables, fruits, eggs, fish, animal meat, etc.). ), not from drinking water. ?

Is it unscientific to say that drinking pure water leads to the loss of nutrients in the body?

There is a saying on the Internet: Because the mineral salt content of pure water is close to zero, drinking pure water can not only bring nutrition, but also dissolve some nutrients in the body and excrete them. ?

Some people think that drinking pure water will decalcify and lead to osteoporosis, which is ignorance of human physiological conditions. The main causes of calcium loss are age, hormone level and dietary intake. ?

Excerpt from: Science and Technology Daily 2065438+July 29, 2004 "Will drinking pure water affect your health?" 》?

If you feel like listening to a hundred opinions, there will be other videos and official authority seals at the end of the article. ?

bottled water

Bottled water and bottled water cannot guarantee the safety and qualification of 100%. 20 14, several well-known bottled water brands were found to be unqualified. ?

Sometimes, water is ok, but plastic bottles (barrels) containing water will bring health risks.

For various reasons, plastics will not be properly treated as we thought. "Recyclable" is not necessarily "real recycling", and plastic pollution is a potential problem.

We always laugh at the messy circle of friends of middle-aged and elderly people, with stories, talks about health preservation and rumors based on real evidence. We always remind parents and relatives not to trust friends to spread information. In fact, as post-80s and post-90s, we will be misled unconsciously?

Facing the blind spot of knowledge, regardless of age. If you don't understand and want to find out, spend more time learning from official, scientific or professional channels.
