Water purifier product market research
A classification of water treatment equipment
Choose what kind of water purifier, mainly based on the location of the residence of the quality of the water, the individual's drinking water needs, and the treatment effect to decide. Currently on the market a wide variety of water purifiers, the following for you to analyze the advantages and disadvantages of a variety of water purifiers
1 cartridge water purifier
This water purifier uses a cartridge structure, according to different needs, can be matched with different cartridges, the advantage is that the price is cheaper, the filtration accuracy is higher (containing ultra-filter). The disadvantage is that the life of the cartridge is relatively short (for example, the life of the PP cotton in 3-5 months, the life of the activated carbon in about half a year, the life of the ultra-filtration 1-2 years), the water output is small, only suitable for drinking.
2 water purifier
This water purifier uses RO reverse osmosis technology, first appeared in the aviation industry, is to solve the problem of drinking water for the pilots and research and development, the advantages of high precision water (in addition to water molecules, any substance can not), the disadvantage is that the purified water is too pure, the lack of trace elements are beneficial to the human body, an average of a cup of pure water, to produce 3 cups of waste water, and must use electricity. At the same time must use electricity.
3 Ionizer
Through electrolysis, the water will be electrolyzed into acid and alkaline two kinds of water, alkaline water for drinking (because the human body is an acidic structure, often drink alkaline water, can regulate the acid-base balance, and promote the metabolism), acidic water used for bathing (or used to sterilize and disinfect), and at the same time, through electrolysis, to change the molecular group of the water (water will be changed to 6 molecular groups of small molecules). ). This kind of water machine was first used as a medical device, for common skin diseases have some curative effect. His disadvantage is the high cost (ordinary about 6 thousand), while the pH value of the water also depends on the electrolysis version, which requires electricity.
4 Magnetized water machine
Pros: through magnetization, change the molecular group of water, more conducive to human absorption. Cons: People with gastrointestinal disorders should be cautious, because magnetized water has a certain degree of gastrointestinal stimulation.
5 Central water purifier
Installed in the home of the water purifier on the main water supply pipe, so that all the water in the home are purified, the advantages of a long life of the filter media (the shortest is also 5 years), easy to operate, and at the same time with the function of backwashing can extend the life of the filter media. The disadvantage is that the purification precision is not particularly high, if used to deal with drinking water, the effect is not particularly good
Two water purifier classification
From the appearance of the specific can be divided into a single-stage treatment of the water purifier, a single-stage multi-layer (composite filter media) water purifier, multi-stage processor three.
Single-stage processing water purifier is only a filter canister filter media, its function is relatively single, mainly play a pre-treatment (such as PP cotton, ceramic filter media, etc.) and a single water quality improvement (such as the dechlorination of activated carbon, etc.). Due to China's water pollution, tap water secondary pollution is serious, single-stage treatment of water purifier only play a primary filtration role, need to be used in conjunction with other filters, the filtered water is not directly drinkable
Single-stage multi-layer (composite media) water purifier refers to the same cartridge with more than two filter composite composition, level by level in the distribution of the filter cartridge. The source water passes through the filter media step by step, removing impurities and other harmful substances in the water. The use of single-stage multi-layer (composite media) of the water purifier of each level of filter media filtration accuracy is generally lower, the only way to maintain a larger flow; single-stage multi-layer (composite media) of the life of the water purifier depends on the service life of the shortest filter material, due to the service life of each level of the filter media is different (some of them are determined by the time, and some of them are determined by the flow rate) when the service life of the shortest need to be replaced, it is necessary to replace all of them. Replacement, or water quality decline. So the whole must be replaced, the cost is higher.
Multi-stage treatment of water purifier is a combination of different filter media (more than 2 kinds of) composed of water purifier, the market is mostly seen microfiltration and ultrafiltration filter media, microfiltration filter media and reverse osmosis filter media combined into a water purifier, according to the number of filter media can be divided into 3 water purifier, 4 water purifier, 5 water purifier ....... According to its combination can be divided into ultrafiltration water purifier, reverse osmosis water purifier, from the coarse filter cartridge to the UF membrane cartridge or RO membrane cartridge progressive filtration system has become the trend of the water purifier market. Multi-stage water purifier is not the more the number of levels to deal with the better the effect of water quality depends on the filtration precision of each level of filter material, the higher the precision of the filtration effect is better. The more levels of multi-stage water purifiers not only have the redundancy of the snake, but also invariably increase the economic burden on consumers.
Single-stage filtration water purifier and can not reach the drinking water quality standards, level by level multi-stage water purifier, according to the filtering accuracy of all levels of filter cartridges layer by layer filtration of impurities in the water, for example, PP cotton filtration accuracy of 5 microns or so, to filter out rust, sediment and other large particles of matter; ultrafiltration membrane (UF membrane) filtration accuracy of 0.01 microns, to filter out bacteria viruses, etc.; reverse osmosis membrane (RO membrane) filtration accuracy of 0.0001 microns, to filter out water alkali, sand, etc.; the filtration accuracy of 0.0001 microns. Reverse osmosis membrane (RO membrane) filtration precision of 0.0001 microns, filtering out water alkali, heavy metals, viruses, bacteria, etc., level by level multi-level filtration to achieve water purification and achieve the purpose of direct drinking.
Three treatment process
The water purifier treatment process on the market can be broadly divided into two categories, one is the chemical treatment process: chemical principles of water treatment, commonly used ion exchange resins and KDF (copper-zinc alloy); the other is the physical filtration process: the membrane filtration through the precision of the water treatment, commonly used reverse osmosis (RO membrane) technology and ultrafiltration membrane (UF membrane) technology, and the other is physical filtration process: water treatment through the membrane filtration precision, commonly used reverse osmosis (RO membrane) technology and ultrafiltration membrane (UF membrane). Ultra-filtration membrane (UF membrane) technology.
3.1 chemical treatment process
3.1.1 Ion exchange resin
Using the principle of ion exchange, the exchangeable Na+ contained in the resin and water cations (Ca2+, Mg2+, Fe2+, etc.) for ion exchange, so that the container of the water Ca2+, Mg2+ ions content is greatly reduced.
Resin (ion exchange method) is usually used in water softeners, its main role is to remove the water alkali in the water, can not remove impurities, bacteria, viruses and heavy metals in the water, direct drinking is not good for the body, belongs to the life of the water, such as bathing, cosmetology and so on.
3.1.2 KDF (copper-zinc alloy)
Commonly known as Platinum Ion, is a high-purity copper - zinc particles alloy, which can be harmful substances in the water redox reaction, remove heavy metal ions, organics, nitrites, hydrogen sulfide, residual chlorine and chloroform, etc., to achieve the role of purifying water.
KDF (copper-zinc alloy) through the electrochemical oxidation-reduction (electron transfer) for water treatment work, the lack of stability and timeliness, coupled with a relatively short life, more with activated carbon filter media used at the same time, more for the central water purifier. Due to the treatment of water is generally larger, although the water can be further purified, but currently not up to the standard of direct drinking water. Can effectively remove lead, chromium, mercury and other heavy metal ions and residual chlorine in the water, the formation of the potential difference has a good antibacterial, bactericidal effect.
3.2 physical treatment process
3.2.1 Microfiltration (MF)
Filtration accuracy is generally 0.1-50 microns, common PP filter, ceramic filter element, etc. belong to the category of microfiltration, used for simple coarse filtration, filtration of sediment, rust and other large particles of impurities in the water, and can not remove the water bacteria, viruses, Organic matter, heavy metal ions and other harmful substances.
(1) pp cotton
PP cotton cartridge advantage lies in the pore size uniformity, the effect of filtering particles is better, and cheaper. It is a filter used for primary filtration of the cartridge, generally used in the first filtration, the main filtration of suspended solids (sediment, algae, micro-organisms, etc.), filtration accuracy of 1um, 5um, 10um, 20um disadvantage is that it can only remove the large particles, the life expectancy is very short. PP cotton life expectancy of 3 to 5 months can not solve the actual problem of the bacteria and viruses do not work at all, if you do not keep up with the replacement, may produce Secondary pollution, the loss outweighs the gain, pp cotton water purifier, to replace the pp cotton from time to time.
(2) activated carbon
Activated carbon can adsorb impurities and odors in the water, and will not change the structure of the water or the release of substances into the water, the chemical pollution in the water also has a better adsorption effect
Activated carbon adsorption effect is because of the surface of the activated carbon is full of tiny holes, it is relying on the holes to adsorb the role of these holes.
The shortcomings are short life, the life of activated carbon for about half a year, ineffective against bacteria, inside the garbage accumulation of the formation of secondary pollution may be, most of the market fakes, the real thing is difficult to find. Even the big brands are so. Raw water only after activated carbon filtration is not directly drinkable
(3) ceramic
Ceramic cartridge is mainly used for drinking water fine filtration, anti-bacterial and activation treatment, at the same time can remove heavy metal ions in the water, the full removal of residual chlorine in the water, organic chemicals, colors and odors, through the use of the cartridge to access the mineralization, purification and activation of drinking water. The product can be applied to water purifier, barrel water and water supply
The cartridge can be washed repeatedly, especially suitable for use in muddy water with high turbidity, and has a long service life.
Physical filtration, instant purification and instant drinking, high safety coefficient;
Simple and convenient use and maintenance.
3.2.2 Ultra-filtration (UF membrane)
Ultra-filtration (UF) is a kind of membrane separation technology utilizing differential pressure, the filtration precision reaches 0.01 micron, which can filter out the rust, sediment, bacteria, macromolecules of organic matter and other harmful substances in the water, and retain the mineral elements that are beneficial to the human body.
The water inlet method can be divided into two types: external pressure type and internal pressure type. External pressure type: the raw water from the membrane filament outside the entry, the water from the membrane filament within the system, the external working pressure is lower than the internal type, stable performance, filtration precision lasting unchanged. On the contrary, the internal pressure type, its performance is not stable, the use of a period of time will decline in filtration accuracy.
Nowadays, external pressure type ultrafiltration membrane is widely used in water purification equipment, and internal pressure type ultrafiltration membrane has been gradually withdrawn from the market.
The advantage is that the water output is large, 100% bacteria filtration filtration, durable, very little waste water, the disadvantage is that the flavor removal effect is not ideal, there are good and bad place is the ions can not be removed.
3.2.3 reverse osmosis (RO membrane)
Reverse osmosis technology is an ultra-high-precision use of differential pressure membrane separation technology, filtration accuracy of 0.0001 microns or so, almost all the impurities in the water can be filtered out (including harmful and beneficial), only allows water molecules to pass through the ability to harmful impurities and viruses are completely removed.
While China's research on reverse osmosis purification technology has been many years, but the production quality of domestic reverse osmosis membrane compared with foreign developed countries there is a large gap in the choice of water purifier should pay attention to this, it is best to choose to import reverse osmosis membrane.
The advantage is that the water is almost pure water, the disadvantage is that the amount of water is very small (only a few liters per hour to a dozen liters), too much sewage water (is one to three times the clean water), the need for electricity, and must be used to multi-pole filtration, the need for frequent replacement of filter elements, short life. And because the ions in the water is filtered out may lead to the human body lack of calcium and zinc.

3.3 Filter Media
3.3.1 Maifanshi
Maifanshi is a kind of natural medicinal mineral, containing potassium, sodium, calcium, magnesium, phosphorus and zinc, iron, selenium, copper, strontium, iodine, fluorine, metasilicic acid and other eighteen kinds of trace elements essential to the human body. Trace elements account for about 0.025% of a person's body weight, although its content is very small, but it plays an important role in the process of human life, they are not enough or too much in the human body will affect the health, and even endanger life.
Advantages: strong adsorption; dissolved minerals; adjust the water quality. Disadvantages: unhygienic, long after the bacteria will grow, plus the filter itself can not be sterilized
3.3.2 Tourmaline
Tourmaline filter media is mainly composed of tourmaline particles, tourmaline balls. Used for water purification can enhance the activity of drinking water or make the air produce negative ions increase. Negative ion water is the tap water after treatment, and then by the negative ion generating materials, it has the following characteristics: alkaline, free of bacteria, organic matter, containing minerals in the ionic state, it is a small group of molecules, solvency and penetration
Tourmaline advantages
(1) produce negative ions. Tourmaline can produce a permanent weak current, negative ions can make the body and mind relax, activate cells, improve the natural healing power, and can inhibit the body's oxidation or aging, in addition, negative ions also has the effect of deodorant.
(2) Produce electrolyzed water. When water is electrolyzed, it is possible to obtain various effects such as interfacial activation and removal of silica mucilage (microbial aggregates), etc. When tourmaline reacts with water, it is possible to deal with problems that are difficult to deal with even with chemical detergents and chemicals.
(3) Emits far-infrared rays. Can emit 4-14 micron growth light, far infrared line can penetrate the deep parts of the body, warm cells, promote blood circulation, so that the metabolism is smooth, Tourmaline far infrared emission power of nearly 100%, the value is higher than other minerals.
(4) contains trace minerals. Tourmaline contains a variety of natural minerals, many minerals have a great help to human health, through the tourmaline issued by the weak electric current, minerals are easily absorbed by the body, is an excellent source of minerals
Tourmaline ceramic ball can decompose the organic matter into carbon dioxide and water, etc., and absorbs the harmful metal ions, and will not dissolve into the safety of the metal, in line with the safety conditions.
Tourmaline ceramic ball treated water. It meets the water quality standard of safe water stipulated by the Food Safety Law.
Tourmaline ceramic ball treated water with reorganization effect can be used not only as drinking water, but also as industrial water, food processing raw material water, fish farming water, agricultural water, livestock with treated water and other industrial water. In addition, the advantage of tourmaline ceramic ball treated water is that even if it is used in food processing, it can make the water in it reorganize and play a very good effect, and this reorganization effect can play the same effect on the water used in cosmetics or the use of water-based raw materials and chemical products
Basic conditions for tourmaline to play a role in its performance
(1) Convection: The flow of air, water, or the inhalation of air will form a convection. inhalation of air, all will form convection.
(2) Temperature difference: Not only warmth, but also cooling can be powerful. Covering the body can block the sun.
(3) Moisture: not only contact with water, even to the moisture in the air or sweat, can work.
(4) Pressure: Add to the pressure of gravity, water pressure, air pressure, etc., only the pressure that can contact the degree of the body.
(5) friction: vibration or rubbing the friction can lead to a strong effect. When tourmaline and its living supplies contact with the body, contact with the body's moisture, body temperature, pressure, through the activities of the body, can produce friction and convection. Therefore, when tourmaline comes into contact with the human body, it is most effective
