Direct drinking machine is a kind of equipment that provides direct drinking water, similar to household water purifier. It filters out impurities in tap water through the built-in filter element, and outputs drinking water with up-to-standard quality. This device is often used in public places such as parks to provide convenience for passers-by.
Direct drinking machine can be divided into household type and experimental type, and direct drinking machine of pure water engineering machine can be divided into two types at present [1]: one is a machine for producing pure water (also known as terminal water purification equipment), which can directly drink raw water after filtering (physical method). Municipal tap water whose water quality meets the Hygienic Standard for Drinking Water Quality (200 1) issued by the Ministry of Health of China is used as raw water. The raw water is pre-filtered by two activated carbon filter elements (1 granular activated carbon, 1 sintered activated carbon) and 1 PPF spray filter elements, and then the pre-filtered water is forced to pass through RO (reverse osmosis) with a pore size of one ten thousandth of a micron.
The pH value of water (which makes the prepared purified water sweet and mellow) produces purified water. This water purifier can be turned into a water purifier. There is also a pipeline direct drinking machine, that is, RO reverse osmosis water purification system (called RO direct drinking machine) or UF ultrafiltration membrane water purification system (UF direct drinking machine) is installed in the pipeline direct drinking machine to form an integrated direct drinking machine. water filter
Pure water machine
The first kind of direct drinking machine can be called water purifier. The water purifier introduces the advanced ultra-low pressure reverse osmosis technology and accessories from the United States, and produces the most advanced water purifier for household and group use in China. The water produced by the device has high quality, safe operation, stability and reliability, simple operation and small floor space, and can effectively remove calcium, magnesium, bacteria, organic matter, inorganic matter, metal ions and radioactive substances. The water purified by this device is clear and sweet. The device is suitable for families, hotels, hotels, hospitals and other enterprises and institutions to drink clean water. Because the water in the water purifier does not contain any minerals, it cannot be drunk for a long time, especially for children who use purified water for a long time, which will cause diseases due to the loss of trace elements, such as rickets in Shanghai!
Ultrafiltration direct drinking
The second type is ultrafiltration direct drinking machine, which is mainly composed of ultrafiltration membrane and activated carbon. Ultrafiltration membrane is a kind of porous membrane with super "screening" separation function. Only its aperture.
It is 0.0 1 micron. When making water, it is mainly done by the pressure of tap water itself. Compared with bottled water, the pure water produced by direct drinking machine is fresher, more hygienic and safer. It has a wide range of uses: it can be drunk raw or boiled. The most prominent feature in this respect is that the kettle or electric thermos will never scale again. Pure water for cooking is more hygienic and delicious; Bathing with pure water can remove impurities from the skin, moisturize the skin and play a natural beauty effect; It can provide water for small household appliances such as humidifiers, steam irons and beauty instruments, and there will never be annoying white powder; When used together with an ice maker, the ice cubes made are crystal clear without any peculiar smell.
All-physical water production process
Most water purifiers use reverse osmosis technology: reverse osmosis was originally reverse osmosis, which was developed by NASA with the support of the government. After years of research, it cost billions of dollars. The principle of reverse osmosis is to apply a pressure greater than the natural osmotic pressure on the raw water side, so that water molecules can reverse permeate from the high concentration side to the low concentration side. Because the pore size of the reverse osmosis membrane is much smaller than hundreds or even thousands of times that of the case virus and bacteria, all kinds of viruses, bacteria, heavy metals, solid soluble substances, polluted organic substances and calcium and magnesium ions cannot pass through the reverse osmosis membrane at all, thus achieving the purpose of softening and purifying water quality.
All-physical water production process:
RO reverse osmosis membrane water purifier
1, the world's most advanced RO reverse osmosis membrane is used to treat water, and the filtration accuracy is 0.00 1 micron, which ensures the drinking water quality, which means that the reverse osmosis water of this water purifier is very pure. This product is suitable for pure water in units, factories, food, beverages, medicine, electronics, chemical industry, hollow equipment, glass cleaning, microelectronics industrial equipment and families. 2. Imported brand-name ultra-quiet diaphragm pump has long service life and reliable operation quality. 3. Five-stage filtration, giving full play to the effective functions of each filter element, removing harmful impurities such as sediment, suspended solids, colloid, organic matter, heavy metals, soluble solids, bacteria, viruses, ions, inorganic salt ions, heat sources, etc. in raw water, leaving only water molecules and dissolved oxygen. 4. It has the function of high-pressure washing the reverse osmosis membrane, and it can be washed automatically every 2 hours, which can effectively prolong the service life of the reverse osmosis membrane. 5.

Instant drinking, high purity and low cost, which can completely meet your water and drinking needs. 7. This product is suitable for individuals, units, factories, food, beverages, medicines, electronics, chemicals, hollow equipment, glass cleaning, pure water for microelectronics industrial equipment, and direct drinking water for families and schools. 8. You can decide which type of RO reverse osmosis pure water machine to buy according to your water consumption.
water treatment
General direct drinking machine (water purifier) adopts world-class RO membrane reverse osmosis technology and ultrafiltration membrane pretreatment. The pore size of RO membrane is extremely small, and other molecules larger than water molecules cannot pass through it, so the water filtered by RO membrane is the cleanest water. Six-stage dual-core water purifier
[2] Ordinary direct drinking machines bring you a healthy life through six-stage filtration and industry-leading technology. The general six-stage purification process of direct drinking machine: the first stage: 5 micron PP cotton filtration to remove all kinds of suspended solids. Such as dust, sand, rust, etc. The second stage: active carbon filtration to remove various molecular pollutants in water. Such as chemical fertilizers, pesticides, herbicides, chlorine, bleaching powder, etc. The third stage: 1 micron PP cotton filtration, only substances below 1 micron are allowed to pass through the fourth stage: ultrafiltration membrane: it can remove nano-scale pollutants and effectively protect RO membrane. The fifth stage: RO membrane reverse osmosis technology to remove bacteria, viruses, heavy metals and organic matter from water. The sixth stage: later bacteriostasis.
purification system
The purification system of the standard direct drinking machine [1] sets the flow rate according to the capacity of the filter element, removes different pollutants at one time and comprehensively purifies. Six different modes of purification materials are compounded in proportion and placed in five filter elements A, B, D, E and F respectively, and then form a unique twelve-stage purification system with C filter element. Filter element: The self-cleaning polymer separation membrane is placed at the first position of the whole machine, and combined with high-efficiency iodine enzyme sterilization, a complete throttling device is formed to remove physical contamination and biological pollution. However, the equipment intercepts the captured bacteria and the microorganisms will be killed immediately. This unique purification method is unique in most water purifiers sold in the water purification market. Most water purification equipment is filtered by ultrafiltration in the early stage, rather than being directly killed by bacteria. This will cause bacterial pollution in the whole process and make the material lose its function in a short time. B filter element: KDF is compounded with special microcrystalline carbon and iodine catalase is added at the same time. This unique compound mode can give full play to the excellent purification mode of KDF itself, and at the same time, KDF can extend the purification capacity and life of microcrystalline carbon by more than ten times, and remove chemical pollution and physical contamination (that is, heavy metal pollution). D filter element: Bayer ion exchanger is used in D tube, which softens water extract and removes a lot of calcium and magnesium under unique aseptic conditions. The ion exchanger is easily eroded by iron bacteria, and the bacteria lose their effectiveness. However, most common water purifiers do not have any bacteria interception protection for Bayer's example exchange device, so the effect is limited! Katis, microcrystalline carbon and KDF are fully added to E filter element, which not only has excellent purification ability, but also has stable and safe effect during long-term use. This is difficult for ordinary water purifiers to do. Ordinary water purifiers still have certain effects in the initial stage of use, but it is difficult to ensure the quality of purified water after three months of use. Even completely lost its function. F filter uses molecular sieve with a pore size of only 0.005 mm to filter water, and then thoroughly purifies and deeply treats the water. Finally, check the water body to create safe crystallized living water at all times. C filter element adopts unique high-tech and high-energy polar polymer, and relies on its special micropore and micro-electrolysis effect to comprehensively comb the water body and activate it into high-energy running water that fully meets physiological needs.
