EspañolThe water purifier is a product that can remove suspended solids in water and harmful organic compounds, inorganic compounds, heavy metals, and bacteria that are harmful to the human body, and retain the vector elements and minerals required by the human body. Although the water treated by the water purifier is no different from the original water on the surface, the water quality has changed significantly.
(1) Rust
The water is transported by galvanized iron pipes. The water and iron undergo oxidation to produce red iron oxide, and further oxidation will produce black iron trioxide. Pipes in new buildings are more susceptible to oxidation. Almost all people have this experience. When you turn on the faucet for the first time every morning, the redness in the water is rust. Iron is an essential element for 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 taste the taste of rust, then the iron content in the water is greatly exceeded. The iron content exceeds the standard, not only the look and taste is poor, long-term drinking will increase the burden on the kidneys and lead to the endocrine system Disorders, hypertension and other diseases.
(2) Bacteria
Whether it uses surface water or groundwater as the water source, bacteria and E. coli in tap water can be said to be ubiquitous. Water is the source of life. Water contains nutrients, and water has relative thermal stability, which provides an excellent environment for the growth and reproduction of various bacteria. Even if the water contains very small amounts of nutrients, bacteria and viruses will survive and breed. All people know the dangers of bacteria and viruses.
(3) Chlorine
Chlorine is a strong oxidant with a pungent odor and unpleasant taste. Chlorine is a widely used water disinfectant in the world. Residual chlorine is chlorination disinfection, the amount of chlorine remaining in the water after a certain period of exposure. According to international requirements, the safe amount of residual chlorine should be kept at 0.05 mg/liter at the end of the pipe network (household taps) to control the growth of bacteria during the transportation process. Therefore, municipal tap water contains residual chlorine.
The working principle of the water purifier is to purify the water layer by layer through various filter elements to achieve the purpose of removing impurities. The filter element of the water purifier mainly includes refined PP cotton filter element, activated carbon filter element, etc... Filter elements with better materials can not only remove impurities such as sand, rust, bacteria, suspended solids, etc., remove peculiar smells in water, but also remove calcium in water , Magnesium and other metal ions and radioactive substances to purify water quality.
