Mineralized water at outlet of water purifier
The core filter elements of water purifier and water purifier are different. The core filter element of water purifier is nanofiltration membrane. The core filter element of water purifier is ro diaphragm; The different filtration precision of nanofiltration membrane leads to different water purification effect
the water purifier has no water pump and no power supply. It is driven by water pressure to achieve filtration without water storage tank. It can filter out certain impurities and bacteria in tap water, and the water can reach the drinking standard. At the same time, it retains certain impurities and trace elements that are useful to human body. It is recommended to heat and drink
the water purifier has a water pump, which needs a power supply and a water storage tank. There is a certain amount of waste water, and the water quality is basically free of impurities. The water proced by the water purifier is pure water, which is equivalent to the pure water we bought. The water purifier can only filter impurities, bacteria and so on. The water purifier also filters out the metal ions in the water, including trace elements, and can be drunk directly

the function of the water purifier is to remove the floating objects, heavy metals, bacteria, viruses, resial chlorine, sediment, rust, microorganisms, etc. in the water. It has high-precision filtration technology. The fifth stage filtration technology of the water purifier for household use, the first stage is also known as PPF filter element, and the second stage is UDF filter element, The third stage is precision compressed activated carbon (CTO) filter, the fourth stage is reverse osmosis membrane or ultrafiltration membrane, and the fifth stage is post activated carbon (small t33)
the water purifier is not only suitable for the areas where the tap water is seriously polluted, but also can filter the resial chlorine in the conventional tap water and improve the water consumption. In August 2013, the general office of the national health and Family Planning Commission issued the "management specification for labels and instructions of procts related to drinking water health and safety", indicating that the labels and instructions of water related procts should not be marked with "acidic water", "alkaline water", "activated water", "small molecule group water", "functional water", "energy water", "oxygen enriched water" and other contents
The possible reasons are as follows:
-
RO membrane is the core component of water purifier, which filters out organic matter, metal ions, bacteria and other impurities in water. It is recommended to replace several filter elements together when changing the core. Otherwise, if the impurities filtered by RO membrane are not removed in time, they will cover the surface of the membrane and cause blockage. The amount of water proced will be greatly reced
-
it is possible that the pressure tank is blocked or the pressure of the pressure tank is too low. If the pressure of the pressure bucket is too low, even if a lot of pure water has been stored, the pure water can not be released, and the water flow is still very small
-
if the filter element is a composite filter element, do not disassemble the composite filter element by yourself, because the composite filter element used by most manufacturers is welded by ultrasonic, and once disassembled, it cannot be restored
-
or the accuracy of the filter element is too high

water purifiers can be divided into many types according to different purification principles and processes. Among them, RO reverse osmosis technology has the highest filtration precision (filtration precision is 0.0001 μ m). Because the pore diameter of RO reverse osmosis membrane is only one thousandth of the diameter of hair, only water molecules and dissolved oxygen are allowed to pass through, almost all impurities in water, such as pesticides, bacteria, viruses, heavy metals and other harmful substances, are intercepted and eliminated. In addition to reverse osmosis technology, there are many other filtration technologies: nanofiltration (filtration accuracy between 0.001-0.0001 μ m), ultrafiltration membrane (filtration accuracy between 0.1-0.01 μ m), fine filtration (filtration accuracy below 0.1 μ m, such as ceramic filtration, PPC cotton filtration, etc.)
the ppcotton in the water purifier can effectively remove rust, sand, colloid and all impurities with a diameter greater than 5 microns. The granular activated carbon filter element has strong adsorption capacity, which can effectively absorb resial chlorine, odor, heterochromaticity, pesticides and other chemicals in the water; Precision activated carbon filter can effectively remove bacteria, toxins and heavy metals in water
with the application of deep water purification technology in the field of drinking water, the phenomenon of "acclimatization" will soon become history, which effectively solves the local diseases caused by excessive harmful minerals in groundwater in many places.
1. High voltage switch failure. When the machine is full of water, the pressure switch should jump to turn off the power. If it fails, the machine will work all the time, resulting in constant waste water flow. Judgment method: close the pressure barrel ball valve, the pump continues to work, the high-pressure switch must be out of order, replace it
2. After the machine is full of water, the pump stops working, and the water inlet solenoid valve should cut off the water inlet. At this time, if the waste water outlet has been running water, the inlet solenoid valve may be out of order. Judgment method: close the inlet ball valve, stop the waste water, it can be sure that the inlet solenoid valve is out of order, just replace it
3. Check valve failure. After the machine is filled with water, the pump stops working. If the check valve fails, the pressure bucket will flow back to the RO membrane shell and flow out through the waste water outlet. Judgment method: close the ball valve of the pressure tank, stop the waste water, it can be sure that the check valve is out of order, just replace it
extended data
working principle:
first stage: microfiltration membrane: microfiltration membrane removes various visible substances / st and impurities in tap water. These particles come from aging pipes, rusting, secondary pollution of roof water tanks and so on
the second stage: compressed carbon: compressed carbon to remove chlorine and organic impurities, such as harmful pesticides. It can also absorb the odor, color and odor proced by organic compounds in water, which come from the disinfection by-procts of tap water
the third stage: ultrafiltration membrane: ultrafiltration membrane can remove bacteria, viruses, spores and other substances in water
the fourth stage: filter life indicator: the internal structure of the device is gear structure design. With the passage of water, the gear rotates to make an internal axial upward movement until the water outlet is blocked and the water cannot pass through. That is to say, the total water quantity of the water purifier is calculated through the designed stroke, so as to ensure the safety of the water outlet
purchase guide
1. Whether there is a proct hygiene license
when purchasing water purifiers, users must recognize the importance of proct quality. Regulations on the sanitary supervision and administration of drinking water; It has obtained the health license from the superior health supervision department, and has been appraised by the technical supervision department, which conforms to the national standard for drinking water quality
It is very important to choose the right filter elementthe first generation of water purifier mainly through activated carbon, ceramics and other simple filtration, easy to breed bacteria, pollute the water source, can not achieve the effect of clean water source; The second generation of water purifier uses all kinds of artificial polymer membrane filtration, which has significant effect on removing harmful substances in water, but its fatal defect is that it filters out the beneficial trace elements. The third generation of water purifier adopts the nano microcrystalline filter technology, which solves the defects of the second generation of water purifier and filters out the harmful substances and heavy metals in the water. So when you choose a water purifier, you must ask the filter technology and filter material to see if it can meet your own needs
Whether there is a safe and effective sterilization technology There are two ways to sterilize water purification equipment. One is to add disinfectant, which can kill some bacteria, but contains trace chemical components harmful to human health; The second is ultraviolet sterilization, which is internationally recognized as one of the most effective sterilization technologies. Because ultraviolet sterilization is safe and efficient, it can quickly kill almost all bacteria; And ultraviolet sterilization uses physical principles of sterilization, does not need any chemical agents, will not have side effects on the human body Whether there is a perfect after-sales service systemafter purchasing some brands, many consumers can't find the service phone or the address of the service company. This situation makes consumers helpless and causes a waste of resources. Many water purifiers become furnishings; After sales of water purifier mainly focuses on the replacement of filter element. If the filter element is not replaced for a long time, it will pollute the water source, and the water purifier will also become a "sewage purifier". To select water purifier, we must choose perfect after-sales service, such as using customer service system to track customer information, prompting customers and companies to replace filter elements, etc
The water from the household water purifier is the purified water filtered by the ultrafiltration membrane, which can remove the harmful substances such as sediment, rust, bacteria and organic matter in the water, and retain the mineral trace elements beneficial to human body in the water, just like mineral water. Purified water is filtered out by reverse osmosis membrane, which filters out the ions in tap water, no matter beneficial or harmful, very pure
pure water needs to be pressurized and electrified in the process of proction, and a large amount of wastewater is proced, with small water yield, which is usually only used for drinking. However, the domestic water purifier does not need to be pressurized and electrified, and only relies on the pressure of tap water for filtration. In the process of water proction, there is no waste water, and the water yield is large, which can easily solve the purification problem of a large number of domestic water. The quality of water used for washing vegetables, making soup and cooking in the kitchen is very important for health
Can the direct drinking water purifier remove scaleA: the water filtered by ordinary direct drinking water purifier will not form stubborn scaling as quickly as before. Because the main component of scale is usually e to the high content of calcium and magnesium ions in water, the insoluble precipitates such as calcium carbonate and magnesium carbonate formed by heating are combined with suspended solids and colloids in water. The direct drinking water purifier adopts ultrafiltration membrane separation technology, which can effectively remove the colloid and suspended solids in the water. Therefore, the water with higher hardness after ultrafiltration membrane filtration will only present some white powder precipitation of calcium carbonate and magnesium carbonate when reheated, and it will not form stubborn scaling
Do you have a water purifier without electricityA: there is a water purifier without electricity, and the water purifier is directly filtered by the pressure of tap water
Is the conctivity of effluent from water purifier the same as that of tap waterA: the same. Conctivity is an indicator of the content of conctive ions in water, and the water purifier adopts ultrafiltration membrane separation technology, which does not filter various ions in water, so the conctivity is the same as before filtration. But the conctivity does not reflect the quality of water. For example, the conctivity of natural mineral water is much higher than that of pure water
5. How is the proct filtered Such as kitchen water purifier)
A: tap water enters from the water inlet, filters out bacteria, viruses, silt, rust, macromolecular organic matter and other harmful substances in the water through the ultrafiltration membrane, seeps out from the ultrafiltration membrane pipe wall, and then removes heavy metals in the water through the KDF composite filter layer, and flows out from the water purification outlet. The outflow water only contains water molecules and mineral trace elements, So as to achieve purification effect
