Is water purifier useful? You can’t imagine these pollutions!
Nowadays, food safety problems are endless, and even the water that is drunk is not reassuring. So many people choose to use factory price water purifiers to purify tap water again. However, the brands and types of household water purifiers on the market are also very different. Many consumers have questions: Are these water purifiers really useful?
Perhaps many people still don’t realize that 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:
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.
2, 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.
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 that 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 basically contains a certain amount of residual chlorine.
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. Even if the water contains a very small amount of nutrients, bacteria and viruses will survive and breed. Everyone knows the dangers of bacteria and viruses.
So is the water purifier useful?
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 better material can remove impurities such as sediment, rust, bacteria and suspended solids in the water, remove the odor in the water, and remove calcium, magnesium and other organic and inorganic substances in the water to purify and soften the water.
It can be said that there are many benefits to installing a water purifier. You must not realize the benefits of the water purifier below! Come and see.
The benefits of water purifier one: to solve the secondary pollution of tap water
After the tap water is disinfected by chlorine gas, it can kill viruses and bacteria, but it cannot remove heavy metals and volatile substances. After the long-distance transportation of tap water through the pipeline, it is susceptible to secondary pollution, so people basically choose to boil it and drink it again, but Boiling can only solve the bacterial problem, and can’t solve the problems of sediment, rust, heavy metals, volatile substances and bacteria “corpses”. The water quality of drinking water will not be fundamentally improved, and it will cause serious health hazards.
Benefits of water purifier 2: the best choice for replacing bottled water
A barrel of water is about 8 to 16 yuan, and the cost is high. Most of the water is tap water processed by a large commercial water purifier, and there is very little natural mineral water. At the same time, the shelf life of the bottled water is short, and the water dispenser is open after use and is easily contaminated by airborne contaminants. It should be consumed within 3 days, so it is not an ideal drinking water solution.
Water Purifier Benefit 3: Unlike bottled water, which is extremely expensive
Bottled water is listed as daily water by a few wealthy families, but its cost is too high. It is too luxurious for soup, rice, and vegetables.
Water purifier benefit four: reach the standard of raw drinks, lower cost
Household water purifiers can effectively block all kinds of pollutants, such as bacteria, residual chlorine, heavy metals, volatile substances, rust, sediment, and other impurities and harmful substances in the water, and the cost is much lower than that of bottled water. Good taste and good water quality make it an ideal drinking water solution for the family.
