Water for everyone's body is very important, we are in our daily life is to use the water, the installation of water purifiers will make everyone's quality of life greatly improved. German original imported water purifier is of high quality. The following small make-up to give you an introduction to the German original imported water purifier brand which, how much is the price.
What are the brands of water purifiers imported from Germany? What is the price?
The German original imported water purifier brands have strong force, Hanston.
The price is usually in the range of 3,000 yuan to 8,000 yuan. (Price source network, for reference only.)
What are the water treatment methods of water purifier
1. Softening method
It refers to the hardness of the water (mainly calcium and magnesium ions in the water) to remove or reduce the water to a certain extent. Water in the softening process, just soften the water quality, and can not improve water quality.
2. Distillation
is the process of boiling water and then collecting the steam to cool and condense it into a liquid. Distilled water is extremely safe to drink, but there are some issues to explore further. Since distilled water does not contain minerals, this has become a reason for opponents to suggest that the human lifespan is prone to aging. In addition the utilization of distillation is costly, energy consuming and does not remove volatile substances from the water.
3. Boiling method
The boiling of tap water is an ancient method that is commonly used in China. Boiling water kills bacteria, but some chemicals and heavy metals cannot be removed, even at very low levels, so it is still unsafe to drink.
4. Magnetization method
It refers to the use of magnetic field effect to treat water, known as water magnetization treatment. The process of magnetization is water in the direction perpendicular to the magnetic lines of force through the magnet, that is, to complete the process of magnetization. China's magnetization of water is still in the practice and research of the primary stage, foreign water purifiers do not have the magnetization function requirements, because the magnetization of water does not belong to the scope of water purification, but belongs to the medical aspects of the problem.
5. Mineralization method
It refers to the purification of the basis of the water to add beneficial mineral elements (such as calcium, zinc, strontium and other elements). Commercially available water purifiers are generally added in the water purifier to achieve the purpose of mineralization, but the State Ministry of Health has explicitly pointed out that: "water-related products shall not be advertised as any health function.
6. Ozone, ultraviolet sterilization
These aspects can only be sterilized, remove heavy metals and chemicals in the water, by killing the bacterial carcasses still remain in the water, and become pyrogen.
7. Activated carbon adsorption
Can be divided into the following three forms
7.1, granular activated carbon is more commonly used, mostly wood, coal, shell (core) and other carbon-containing substances through the chemical method or the physical activation method. It has a very large number of micropores and specific surface area, and thus has a strong adsorption capacity, can effectively adsorb organic pollutants in water. In addition, in the activation process, the surface of the activated carbon non-crystalline parts of the formation of a number of oxygen-containing functional groups, these groups make the activated carbon with chemical adsorption and catalytic oxidation, reduction properties, can effectively remove some metal ions in the water.
7.2, silver activated carbon will be activated carbon and silver combined together, not only organic pollutants in the water has the role of adsorption, but also has a bactericidal effect, and in the activated carbon will not grow bacteria, to solve the water purifier water sometimes nitrite water purifier with a high amount of problems. When the water passes through the silver activated carbon, silver ions will be slowly released to play a disinfection and sterilization effect. As the activated carbon to remove the water color, bromine, chlorine, iron, arsenic, mercury, cyanide, phenol, etc. has a better effect, sterilization effect of more than 90%, so it is applied to small-scale water purifiers.
7.3, fiber activated carbon organic carbon fibers formed after activation treatment of a new type of adsorbent material, with a developed microporous structure, a huge surface area, as well as numerous functional groups. Foreign countries in the use of fiber activated carbon for solvent recovery, gas purification, etc. has made remarkable achievements; in the application of water treatment has also done a lot of research work.
8. RO reverse osmosis membrane
RO reverse osmosis is a kind of reverse osmosis through the international popularity of reverse osmosis and other methods of filtration of raw water treatment (physical method) without adding any compounds and produce pure water for direct human consumption of the machine (also known as terminal water purification equipment). Using water quality in line with the Chinese Ministry of Health "Health Code for Drinking Water Quality" (2001) provisions of the municipal tap water for the raw water, through the two activated carbon cartridge (1 granular activated carbon, 1 sintered activated carbon) 1 PPF soluble spray cartridge pre-filtered raw water, and then the pre-filtered water pressure to make it pass through the aperture size of one-ten-thousandth of a micron of the RO (Reverse Osmosis, Reverse Osmosis) membrane, then the pre-filtered water to make it pass through the pore size of one-ten-thousandth of a micron of the RO (Reverse Osmosis, the English? Osmosis) membrane, and finally through the material for the shell (coconut shell) silver-carrying activated carbon (also known as small T33) to adjust the pH of the water (so that the taste of pure water to become sweet and mellow) and the production of pure water.
RO reverse osmosis water purification mechanism out of the pure water relative to the barrel of water is fresher, more hygienic, safer, it is very wide range of uses: you can drink raw, you can also boil and drink, the most prominent feature in this regard is that the kettle or heater will no longer be scaling; Pure water used for cooking, more hygienic, more tasty; Bath with pure water, you can remove impurities on the skin, moisturize the skin, play a natural Beauty effect; can be provided to humidifiers, steam irons, beauty instruments and other small appliances need water, will never let a person hate the scale; and ice machine supporting the use of ice made of crystal clear, without any odor.
Reverse osmosis technology: reverse osmosis is REVERSE?OSMOSIS, which is a collection of scientists from NASA,? Under government support, spending billions of dollars, after years of research and become. The principle of reverse osmosis is in the original water on one side of the pressure than the natural osmosis pressure is greater, so that the water molecules by the concentration of a high side of the reverse osmosis to the concentration of a low side. Due to the pore size is much smaller than viruses and bacteria hundreds of times or even thousands of times more, so a variety of viruses, bacteria, heavy metals, solid soluble matter, pollution of organic matter, calcium and magnesium ions and so on can not pass through the reverse osmosis membrane, so as to achieve the purpose of softening and purification of water.
9. Microfiltration
Microfiltration is made of cellulose or polymer microporous membrane, the use of its uniform pore size to retain particles in the water, bacteria, colloids, etc., so that it is not removed through the membrane. This microporous membrane filtration technology, also known as particle density filtration technology, is capable of filtering micron- or nanometer-sized particles and bacteria.
10. Ultrafiltration
Principle of ultrafiltration: ultrafiltration is a pressurized membrane separation technology, that is, under a certain pressure, so that small molecules of solutes and solvents through a certain pore size of the special film, and so that large molecules of solutes can not pass through the membrane to stay on one side of the membrane, so that the large molecules of material to get part of the purification. The principle of ultrafiltration is also a membrane separation process principle. Ultrafiltration microporous less than 0.01 microns, can completely filter out the water bacteria, rust, colloids and other harmful substances, to retain the original trace elements and minerals in the water.
Ultra-filtration membrane: is a pore size specifications consistent, rated pore size range of 0.001-0.02 micron microporous filtration membrane. Ultrafiltration membrane according to the different membrane materials are divided into inorganic membrane and organic membrane, inorganic membrane is mainly ceramic membrane and metal membrane. Organic membranes are mainly made of polymer materials, such as polyvinylidene fluoride? (PVDF), polyethersulfone? (PES), polypropylene? (PP), polyethylene (PE), polyacrylonitrile (PAN), polyvinyl chloride (PVC)? etc. For example, LISI water purifier uses PVC alloy membrane, the advantages of this membrane are good hydrophilicity, high precision perforation and corrosion resistance.
Ultra-filtration water purifier: ultra-filtration water purifier out of the water can be thoroughly filtered out of the water bacteria, rust, colloids and other harmful substances, but also retain the original trace elements and minerals in the water, supplement our daily needs. Such water is not only safer than plain water, but also healthier than pure water, to a certain extent, can really meet our daily drinking water and water needs.
11. Composite
When a process is difficult to remove harmful substances in the water, the use of two or more than two kinds of processes that are composite. Such as activated carbon adsorption, ultraviolet sterilization, activated carbon adsorption reverse osmosis, activated carbon adsorption microfiltration (overfiltration), polypropylene microfiber, activated carbon, microfiltration (overfiltration). In the composite water purifier, membrane technology composite water purifier water purification performance is excellent, especially in the removal of microorganisms (bacteria, algae, etc.) has a relatively significant effect, some of which are of excellent quality water purifier water can be directly drinking water, has been welcomed by the majority of consumers, and has become a hot spot of the current development of water purifier.
The above article introduces the German original imported water purifier in the market is more recognized brands which, as well as the German original imported water purifier price is how. There are very many types of water purifiers on the market, and there are many different methods for the function of water purification. Different water treatment methods are adapted to different use of the environment, so we should consider clearly before buying their own use of the environment, is in line with the requirements of which product.
