EspañolActive carbon
It is more commonly used. It is made by chemical method or physical activation of carbon containing substances such as essence, coal quality, shell (core). It has a lot of micropores and specific surface area, so it has a strong adsorption capacity and can effectively absorb organic pollutants in water. In addition, during the activation process, some oxygen-containing functional groups are formed in the non crystalline part of the surface of the activated carbon, which make the activated carbon have the properties of chemical adsorption, catalytic oxidation and reduction, and can effectively remove some metal ions from the water.
reverse osmosis
A separation technique in which water is passed under pressure through a synthetic membrane that allows only pure water to pass through, while pollutants are removed. The R / O reverse osmosis technology adopted is a high-tech achievement that the U.S. government and NASA have spent hundreds of millions of dollars to solve the problem of water for astronauts to go to the moon. High cost, suitable for areas with poor water quality.
Composite
When one process is difficult to remove harmful substances in water, two or more processes are used, which are composite. Such as activated carbon adsorption, UV sterilization, activated carbon adsorption, reverse osmosis, activated carbon adsorption, microfiltration (ultrafiltration), polypropylene Microfiber, activated carbon, microfiltration (ultrafiltration), etc. In the composite water purifier, the membrane technology composite water purifier has excellent water purification performance, especially in the removal of microorganisms (bacteria, algae, etc.) has a relatively significant effect. Some of the high-quality water purifier effluent can be directly drunk, which has been welcomed by the majority of consumers and has become a hot spot in the current development of water purifier.
From the above classification method of water purifier, it is not difficult to see that the domestic water purifier is essentially the miniaturization of water supply advanced treatment, and its main treatment objects are turbidity, chroma, heterosmell and organic matters in tap water. It is generally composed of three parts: pre filtration (coarse filtration), adsorption, fine filtration (microfiltration, ultrafiltration, reverse osmosis). Among them, adsorption (usually activated carbon adsorption) and fine filtration are the main means to remove organics, heterosmell and chroma in water. The objective operation conditions directly affect the water quality of the water purifier. The service object of domestic water purifier is thousands of households. However, due to the great difference of water quality and pressure conditions in the use area, the user lacks necessary operation knowledge, and the product design cannot cope with the ever-changing situation. Therefore, the manufacturer of water purifier should take into account that the user can master certain professional knowledge, install and operate the water purifier in a standardized way, so as to make the water quality of the outlet water reach a reasonable level Think about the effect.
Filter media type
In view of the deterioration of the modern social environment, the water pollution is becoming more and more serious, and the pollutants in the water are increasing, such as pesticides, chemical fertilizers and organic concentrates, which are difficult to be removed by traditional water purifiers. Therefore, it is necessary to improve the water purification effect of the water purifiers. The filter medium water purifiers have super removal capacity for water pollution (such as chlorine, pesticides, chemical fertilizers, pesticides, carcinogenic characteristics, etc.), and can retain calcium and magnesium in the water The ingredients beneficial to human body are also recognized by European and American countries!
Active carbon fiber (ACF) is a kind of advanced filter media in the market. ACF is a new type of functional fiber prepared by carbonization and activation with organic fiber as the precursor. It is a new type of functional adsorption material for the third generation products after granular activated carbon and activated carbon rod. It has good formability, acid and alkali resistance, conductivity and chemical stability. ACF has strong adsorption for dust, compounds and heavy metals, and is widely used in food, water purification, fine chemicals, nuclear industry and other fields. JCB ACF is one of the best activated carbon fibers. It can not only remove the residual chlorine, bacteria, compounds and heavy metals in the water, but also restore the sweet taste of the purified water.
