“If you can’t drink clean water, you don’t have clean air, earn too much money is also a dead road.” A clean water source is a topic that has helplessly mentioned on the table. The source of life, now has become a so-called “life quality” that many people have to spend money.
Today, come and talk to you now the home water purifier that is popular. After all, many people want to buy, but it is really inconvenient, so I hope to buy some worth.
Water purifiers can be divided into many types according to different purification principles and processes. Among them, the RO reverse osmosis technology is the highest, and the filter accuracy is 0.0001 microns. Because the aperture of the reverse osmosis film is only 100,000 parts of the diameter of the hair wire, only water molecules and dissolved oxygen passes, all impurities such as pesticides in the water Harmful substances such as bacteria, viruses, heavy metals are almost all intercepted.
First, the principle of water purifier
The principle of water purifiers is actually very simple, that is, the various problems that have a healthy impurity, which is mentioned above, there is a clean water source. The structure is composed of the outer casing, and the more common filter material is mainly:
The first is the stainless steel filter, the minimum pore size can do about 90 microns. About the water you need to know is PP cotton, its microscopic is like our HEPA filter in the air purifier, uses capillary fibers to adsorb large particles, can keep more than 1 micron Impurities.
The third is activated carbon, also used in the air purifier, the active carbon hole diameter is large, there are 0.1 to a few microns, it is to retain the pellets with the interior delay, to the organic matter, odor, pigment Effective. Generally, the second layer will use particulate activated carbon to ensure that the water entering the subsequent membrane reaches the water purification requirements of the diaphragm, and finally uses post-placed activated carbon further adsorbing the residual color and odor.
The fourth softening resin / KDF is placed together because the two materials are also improved in a non-physical filtration. The resin is to remove calcium and magnesium ions in water, and reduce water hardness. However, the price of KDF is very high, so there is less and poor in the filter element.
Further, it is a variety of membranes. The aperture is from 1 to 0.1 μm, and the microfiltration membrane, 100 to 10 nanometers are ultrafiltration membranes, 10 to 1 nanometers of this extremely small pore size called raw filters. The key issue is coming, the water molecules and some heavy metal ions are 0.2 to 0.5 nm, how to separate? This involves a high-tech-reverse osmosis (Reverseosmosis, referred to as the RO) film, which can effectively filter out pure water and leave other ions.
Usually, the internal core used is limited, the PP cotton filter and the activated carbon cartridge which are filtered, and the replacement time is approximately 3 to 6 months; and the core effect is the RO reverse osmosis membrane and ultrafiltration membrane. Use it for 2 to 3 years.
Second, what do home purifications need to be equipped?
- Pre-filtering — front filter:
This device is a crude filtration device that is used to filter large particulate matter such as sediment to protect the laid water and shower sprinkle. The filtering accuracy is 90-110 microns. It is already enough, too small to block, and the front filter of the rebuff is easier to rinse the filter.
- Activated carbon bottle
The function is simple, which is the residual chlorine, odor and variegated in the water in the water. Of course, some high-end central purifiers have some additional functions, convenient to install, strong practical, convenient, and now the mainstream Water equipment.
- Central water purifier / central water sailor (due to the south, here these two water purifiers are not detailed here, because the price is more expensive and the water quality is soft)
- End straight drink machine
This involves direct drinking water such as the kitchen, and is subpristed into a UF ultrafiltration water purifier and RO reverse osmosis pure water machine.
1, uf (Ultrafilteration) ultrafiltration water purifier: The filter accuracy of the ultrafiltration membrane is 0.01 microns, while effective filtering bacteria, viruses and various suspended materials, keep some minerals, trace elements, etc. for us. Various catalysts can remove some heavy metals, and the TDS value has not changed. Southern areas suitable for overall environments or a relatively soft water quality.
Advantages: Allow temperatures and pH ranges, can retain minerals and trace elements for human body, better taste; long life life; can operate in low water pressure, large water, no need to power and pressurize, And relative to other purification equipment, the cost is low.
Disadvantages: The filtering accuracy is not as good as RO, and the heavy metal substance in water cannot be filtered.
2, RO (REVERSMOSIS) reverse osmosis pure water machine: The filtration accuracy of the RO film can reach 0.0001 microns, in addition to the substances that the ultrafiltration water purifier can be filtered, can remove ionic impurities, basically achieve only water molecules Through the RO film, it purifies the water TDS value low.
Advantages: More thoroughly filtration, controlled control, TDS value means that the replacement of the RO film.
Disadvantages: The proportion of pure water and wastewater is 1: 3 (ie, drink 1 cup of pure water, the RO pure water will discharge 3 cups of waste water to sewer), compare wastewater.
※ The reverse osmosis pure water is currently available in the market, there are two types of buckets, and the pure water machine containing buckets. The price is cheaper, but there will be microorganisms in the water storage time, and it is easy to cause secondary pollution. The pure water machine of the bucket, although the reverse osmosis membrane cost is relatively high, but more peace of mind.
Whether it is ultrafiltration water purifier or a RO reverse osmosis pure water machine, the general household water purifier has a 5-level filter structure, and the material is substantially the same. Only the subsequent filtration is selected different separation techniques.
Third, how to choose water purifier equipment?
Understand the quality of tap water, knowing the principle of the water purifier, we understand the same as the air, we now face the impurities in the water, there is no other way, it is a word-filter.
How can I choose according to different needs?
- I just want to filter the impurities, drinking water in daily drinking water, use traditional ways
Front filter: Most foundation, mainly used to protect shower and water heaters
- If there is only a demand for direct drinking water
Easy version: Buy a pure water machine, in the case of protection, water heaters and shower: front filter + pure water machine;
Advanced: Front Filter + Ultrafiltration + Pure Water (Ultrafiltration Protective Effect);
- If residual chlorine is removed
Economic version: Only for drinking water and bath removal of residual chlorine can consider RO pure water machine + bath baby (bath purifier);
House Edition: Central Water Water Machine. However, the price is higher, and it is necessary to consider the house according to the house, according to the position, the whole house, the quality of the filter element is good, the time and replacement frequency is used.
- What is the concept of the reverse osmosis, microfiltration, and ultrafiltration when you buy a water purifier? In fact, this is the title of four different membrane holes used in membrane separation methods. Complete classification is: Microfiltration membrane (MF), ultrafiltration membrane (UF), nanofiltration membrane (NF) and reverse osmosis membrane (RO). The smaller the membrane pore size, the higher the filter accuracy, the greater the working pressure, the slower through the speed
Precautions when purchasing:
First, whether there is a product health license approval.
The importance of product quality must be known when users buy water purifiers. Life drinking water health supervision and management method stipulates that the health license of the superior health supervision department has obtained the identification of the technical supervision department, and it is in line with the national “domesticated water quality standard”.
Second, the purchase of a suitable filter element is critical.
The first generation water purifier mainly filtered through activated carbon, ceramics, etc., which is easy to breed bacteria, pollute water, and does not achieve the effect of clean water; the second generation water purifier uses various artificial polymer filtration, which is harmful to the water The effect is remarkable, but its fatal defect is filtered out of a trace element that is advantageous to the body. The third-generation water purifier uses nano-microcrystalline filter technology, which solves the deficiencies of the second generation water purifier, filtered off the harmful substances and heavy metals in water. So everyone chooses the water purifier, be sure to ask the filtration techniques and filter materials to see if they meet their needs.
Third, whether there is a safe and effective bactericidal technology.
Water purification equipment is bactericidal in two ways, one is to add disinfectant, disinfectant can kill a part of bacteria, but the disinfectant contains chemical compositions that endanger human health; the second is ultraviolet sterilization, ultraviolet sterilization technology is the most recognized international recognition One of the sterilization techniques, because ultraviolet sterilization is safe, efficient, can quickly kill almost all bacteria; and ultraviolet sterilization uses physical principles to sterilize, no chemicals, will not have side effects on the human body.
Fourth, whether there is a perfect after-sales service system.
Many consumers have purchased certain brands, can’t find the address of the service call or maintenance service company. This situation allows consumers helplessness, causing resources to waste, many water purifiers become furnishings; water purifiers After the sale is mainly replaced in the filter element, if the filter is long-term, it will pollute the water source, and the water purifier will become a “sewage”. Choosing a water purifier must select a perfect after-sales service, such as using the customer service system to track customer information, prompting customers and companies to replace the filter.
- The purchase performance price is high.
There are many domestic and imported water purifiers, the brand is also full, everyone is selected according to their own demand and budget, the domestic cost is slightly higher, but there are many cottage, some filter cartridges do not meet the national regulations, need to provide professional authority Test report.
