1. Softening


refers to the hardness (mainly water calcium and magnesium ions) in water to remove or reduce to a certain extent. Water softening process, only soften water and can not improve the water quality.


2. distillation


refers to boiling water, steam is then collected, allowed to cool and condense it. Distilled water is extremely safe drinking water, but there are some issues to be further explored. Since distilled water does not contain minerals, which became the reason for opponents who made life easy aging. Further distillation using a high cost, energy consumption, water can not remove volatiles.


3. Boiling


refers to boiling tap water for drinking, which is an ancient method, in general domestic application. Boiling water can kill bacteria, but some chemicals and heavy metals can not be removed, even if its content is very low, it is still not safe to drink.


4. Magnetization


refers to a magnetization process by a magnetic field effect of treated water, called water. Process of magnetic treatment of water is in the direction perpendicular to the magnetic field lines through the magnet, i.e., the magnetization process to complete the process. China magnetic treatment of the water is still in its infancy practice and research, foreign water purifier does not require magnetization function, because magnetized water outside the scope of clean water, but belongs to medical problems.


5. Mineralization method


refers to again add water purification on the basis of minerals beneficial to human body (e.g., calcium, zinc, strontium and other elements). By adding a commercial water purifier general medical stone in water purifier to achieve the purpose of mineralization, but the Ministry of Health has explicitly pointed out: "wading products may not promote any health functions."


6. ozone, ultraviolet disinfection


These aspects can only be sterilization, can not afford to remove the water of heavy metals and chemicals that kill bacteria through the bodies remain in the water, and to become pyrogenic .


7. Activated carbon adsorption


can be divided into the following three forms


7.1, granular activated carbon is more common, the use of wood, coal, nut shell (core) or the like containing through the carbonaceous materialBy chemical or physical activation legal system. It has a lot of micropores and surface area, which has a strong adsorption capacity, effective absorption of organic contaminants in water. Also during the activation, the activated carbon surface is non-crystalline portion is formed of some oxygen functional groups, these groups make the activated carbon has a chemical adsorption and catalytic oxidation, reduction performance, can effectively remove some of the metal ions in the water.


7.2, activated carbon and activated carbon infiltration silver silver together, not only the adsorption of organic pollutants in water, also has a bactericidal effect, and the growth of bacteria in the activated carbon will not solve the water purifier sometimes nitrite with high tolerance of water purification problems. When the water seepage through activated silver, silver ions will gradually be released, play the role of disinfection. Since the activated carbon to remove water color, bromine, chlorine, iron, arsenic, mercury, phenols, etc. having good results, more than 90% of sterilization effect, so it is applied in a small water purifier.


7.3, a new adsorbent material is activated carbon fiber formed organic activated carbon fibers treated with a well developed porous structure, huge surface area, and numerous functional groups. Foreign countries in adopting fiber activated carbon solvent recovery, gas purification, etc., have made remarkable achievements; also done a lot of research in water treatment applications.


8.RO a reverse osmosis membrane


RO (ReverseOsmosis) is a reverse osmosis by reverse osmosis and other international popular way, without any compound added to the raw water after the filtration treatment (physical method) pure water produced a machine for direct human consumption (also known as water purification equipment terminal). Using water meets municipal tap Chinese Ministry of Healths "drinking water health standards" (2001) for the raw water, raw water pre through two activated carbon filters (1 granular activated carbon, a sintered activated carbon) a PPF meltblown filter filtered, and pressure is applied to the pre-filtered water is passed through a ten thousandth micron pore size RO (reverse osmosis, English ReverseOsmosis) film material is husk by * (coconut shell) of silver on activated carbon (also known as small T33) adjusting the pH of the water (pure water so that the system becomes sweet taste mellow) produced the pure water.


RO reverse osmosis water purification mechanism with respect to the pure water bottled water fresher, more hygienic, safer, its use is very wide: drink can, may be burnedOpen drink, in this regard * prominent feature is the electric kettle or a thermos bottle never furring; pure water for cooking, more health, more palatable; with pure water bath, can remove impurities on the skin, moisturize the skin, play the effect of natural beauty; can be provided to the humidifier, steam iron, beauty instrument and other small appliances needed water, and never annoying scale will appear; use the ice machine supporting, made of crystal clear ice, without any odor.


reverse osmosis technology: reverse osmosis text is REVERSEOSMOSIS, it is a collection of NASA scientists of many countries, in support of the government spend billions of dollars, made after years of research. Applying the principle of reverse osmosis is greater than the natural osmotic pressure of the raw water side, reverse osmosis water molecules by the high concentration of low concentration of one to one. Since the pore size much smaller than the several hundred or even a thousand times or more viruses and bacteria, so a variety of viruses, bacteria, heavy metals, soluble solids, organic pollution, calcium and magnesium ions can not pass reverse osmosis membrane, so as to achieve quality softening purification purposes.


9. Microfilter


microfiltration method is a microporous membrane of cellulose or polymer materials, the use of uniform pore size which is trapped water to the fine particles, bacteria, colloids, etc., so as not to be removed by the filter. This microporous membrane filtration technique, also known as granulocytes density filter, capable of filtering micron or nanoscale particles and bacteria.


10 Ultrafiltration


Ultrafiltration principle: Ultrafiltration is a separation technique plus film, i.e., at a certain pressure, so that the solvent and small solutes through a certain aperture special film, leaving the impermeable solute molecules, remain in the side of the membrane, so that the macromolecules has been purified fraction. Ultrafiltration principle is the principle of membrane separation process. Less than 0.01 micron microporous ultrafiltration, can completely filter out bacteria in the water, rust, colloids and other harmful substances, trace elements and minerals to keep the original water.


membrane: is a consistent, reproducible pore size, the pore diameter range 0.001 to 0.02 micron rated microporous filter membrane. Depending ultrafiltration membrane material into an inorganic film and an organic film, an inorganic film mainly ceramic membrane and the metal film. The organic film is mainly made of a polymer material, such as polyvinylidene fluoride (PVDF), polyethersulfone (PES), polypropylene (PP), polyethylene (PE), polyacrylonitrile (PAN), polyvinyl chloride ( PVC)Wait. For example liters of water purification using an alloy film is PVC, the advantage of such films is good hydrophilicity, high corrosion resistance and punching accuracy and the like.


UF water purifier: UF water purification system both completely out of the water filter out bacteria in the water, rust, colloids and other harmful substances, and to retain the original trace elements and minerals in water , complement our daily needs. Such water than both safe drinking water, health off than pure water, can truly meet our daily drinking water needs and to a certain extent.


11. Compound


When a process is difficult to remove harmful substances in water, the use of two or more is the complex of two processes. Such as activated carbon adsorption, ultraviolet disinfection, activated carbon adsorption reverse osmosis, activated carbon adsorption micro filtration (ultrafiltration), fine polypropylene fibers, activated carbon, microfiltration (ultrafiltration) and the like. In the composite type water purifier, the purifier excellent in the film composite art purification performance, in particular, a relatively significant effect in removing microorganisms (bacteria, algae, etc.), some of the water quality of the water purifier can be directly to drink, has been welcomed by consumers, it has become the focus of the current development of the water purifier.
