Is there any use of the water purifier? Four steps to understand the truth

The brands and types of water purifiers on the market are so dazzling that consumers are not only questioning: Are these water purifiers really useful? What does it purify?

Let’s take a look at the details below with Xiaobian. Even if the water source is pure water, from the water source to the household faucet, and not to mention the pollution of tall buildings and underground reservoirs, there are several kinds of pollution that are inevitable:

First, rust
The water is transported by a galvanized iron pipe, and water and iron are oxidized to form red iron oxide, which further oxidizes to form black ferric oxide. Pipes in new buildings are more susceptible to oxidation. Almost everyone has this experience. The faucet is turned on for the first time every morning, and the red material in the effluent is rust.

Iron is an essential element of the human body, but as one of the indicators of drinking water, the iron content per liter of water must not exceed 0.3 mg.
If the naked eye can distinguish the color of rust in the water or can taste the taste of rust, then the iron content in the water is greatly exceeded, the iron content exceeds the standard, not only the perception, poor taste, long-term drinking, will increase the burden on the kidney, leading to the endocrine system disorders, high blood pressure and other diseases.
Second, lead and other heavy metals
During the transportation process, there will be a lot of heavy metals such as lead dissolved in the water. Long-term drinking will increase the burden on the liver and kidneys of the human body, and easily cause diseases in the liver, kidney, heart, and nervous system.

Third, chlorine
Chlorine is a strong oxidizing agent with a pungent odor and a mouthfeel. Chlorine is a tap water disinfectant widely used internationally.
The residual chlorine is chlorinated and disinfected. After a certain period of contact, the amount of chlorine remaining in the water. According to international requirements, the safety of residual chlorine is the end of the pipe network (at the household tap) should be kept at 0.05 mg/liter of water to control the growth of bacteria in the transportation process, so the city supply tap water contains residual chlorine.

Fourth, bacteria
Whether it is surface water or groundwater as a source of water, bacteria and E. coli in tap water can be said to be ubiquitous. Water is the source of life. The water contains nutrients, and the water has relative thermal stability, thus providing an excellent environment for the growth and reproduction of various bacteria.

Is water purifier useful?
A water purifier is a product that removes suspended solids from water and organic compounds, inorganic compounds, heavy metals, bacteria that are harmful to the human body, and retains the vector elements and minerals required by the human body. The water treated by the water purifier, although apparently no different from the original water, has undergone significant changes in water quality.

The working principle of the water purifier is to purify the water layer by various filter elements to achieve the purpose of removing impurities. The filter element of the water purifier mainly includes a granular activated carbon filter element, a reverse osmosis filter element and a rear activated carbon filter.

The filter element with good material can remove impurities such as sediment, rust, bacteria and suspended solids in the water, remove the odor in the water, and remove metal ions and radioactive substances such as calcium and magnesium in the water to completely purify and soften the water.
