The frequency of draining the waste pipe of the water purifier is related to the brand of the water purifier and the quality of the raw water.
Generally speaking, the waste pipe needs to be drained once when the amount of water coming out of the water purifier is low.
Water purifier (water purifier, water purifier) is the use of water according to the requirements of the water quality of the depth of filtration, purification and treatment of water treatment equipment. The core of its technology for the cartridge device in the filter membrane, the current main technology from the ultrafiltration membrane and RO reverse osmosis membrane two. Water purifier can effectively filter out rust, sand, colloid and adsorption of residual chlorine in water, odor, color, pesticides and other chemicals. It can effectively remove bacteria, germs, toxins, heavy metals and other impurities in water. The application of water purification technology in the field of drinking water effectively solves the endemic diseases caused by the excessive harmful substances in groundwater in many places.
Working principle:
The first level: ? Microfiltration membrane: Microfiltration membrane removes all kinds of visible matter/dust and impurities from tap water. These particulate matter from the pipeline aging, rust, roof tanks secondary pollution and so on.
Second Stage: Compressed Carbon: Compressed carbon removes chlorine and organic impurities such as harmful pesticides. It also absorbs odors, colors and smells produced by organic compounds in the water, which come from tap water disinfection by-products.
Third level: ultrafiltration membrane: ultrafiltration membrane removes substances such as bacteria, viruses and spores from the water.
The fourth level: cartridge life indicator: the device inside the gear structure design, with the passage of water, gear rotation makes an internal shaft upward movement, until the outlet blocked, the water can not pass, that is, through the design of the trip to calculate the total amount of water over the water purifier, so as to ensure that the water is safe.
Water purifier according to the water quality treatment, can be divided into the following 10 categories:
1. Softening method
is the water hardness (mainly refers to the water calcium, magnesium ions) to remove or reduce a certain degree. 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 be explored 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 tap water is boiled to drink, this is an ancient method, commonly used in the country. 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, called water magnetization treatment. Magnetization process is the water perpendicular to the direction of 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 expressly pointed out that: "water-related products shall not be advertised as any health care 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, shells (kernel) and other carbon-containing substances through the chemical or physical activation method. It has a very large number of microporous 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 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 the activation of a new type of adsorbent material, with a developed microporous structure, a huge surface area, as well as a large number of 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 water machine (also known as the terminal water purification equipment). The principle of reverse osmosis is to apply more pressure than the natural osmosis pressure on one side of the raw water, so that the water molecules are reverse osmosis from the side with high concentration to the side with low concentration. 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 water softening and purification.
9. Microfiltration
Microfiltration method 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 does not pass through the membrane and be removed. 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 method
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 substances have been 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.
Filter function: can better improve the taste of water.
11. Activated Carbon Fiber (ACF)
Relative to the granular activated carbon is more fine, the filtration effect is fully improved, the treatment of water flow is greater.
