First, 3M water purification patent
1. This product has passed the test of the National Health Foundation, an international authority.
2. Obtained the gold medal mark of American Water Quality Association and the wading certification of China Ministry of Health.
3. Advanced composite membrane pre-activated activated carbon technology can effectively remove chemicals, heavy metals, odor, chlorine, bacteria, spores and cysts, VOC (volatile organic compounds), MTBE carcinogens (such as methyl tert-butyl ether), scale and impurities.
Second, the characteristics
1 and 3M water purifiers are small in size and flexible in installation, which will not affect the use of the original faucet or damage the original decoration.
2.3M water purifier is small in size, but its function is not less than 5 times of filtration. The 3M water purifier does not need washing, and adopts an integrated disposable filter element, which is convenient for replacement and avoids secondary pollution.
The activated carbon in the 3.3M water purifier is different from other activated carbons. It is a compact activated carbon rod made of superfine powder activated carbon through special polymer materials by high polymerization technology, which can improve the content and effectiveness of activated carbon and remove heavy metals.
4.3M water purifier adopts medical-grade pleated membrane filtration technology, which can effectively remove spores, cysts and bacteria in water and retain the original mineral elements in water.
The 5.3M water purifier is different from other water purifiers in that it does not need a pressure reducing valve, and the water body loses less than 1Gps after passing through the water purifier, so the water pressure loss is very small, so the filter membrane will not burst.

Drinking water filtration technology
I. Classification
At present, most families drink pure water the most. As we all know, the most important thing in water purifier products is the filter element. Household water purifiers on the market are mainly divided into ultrafiltration and reverse osmosis according to the structure of filter elements.
Second, ultrafiltration and reverse osmosis
1, ultrafiltration technology
The pore size of ultrafiltration membrane is about (0.001-0.1) μ m.
Colloid, rust, suspended matter, sediment and macromolecular organic matter in water can be intercepted by ultrafiltration membrane to complete purification. Ultrafiltration water purifier generally does not need water pump and power consumption, which avoids electrical safety problems. Large water output, no waste water, environmental protection and energy saving. In addition, because there are few joints, the water pressure needs to be low, and the normal water pressure of municipal tap water is enough.
Therefore, the failure rate and water leakage probability are relatively low. However, its shortcomings are also obvious. After long-term use, the residue on the membrane surface will affect the water output and need to be cleaned in time. The removal effect of chemical pollutants in water is poor, and the taste of the effluent is average, which can not reduce the hardness of water, and there is still the possibility of scaling in boiling water containers.
2. Reverse osmosis technology (RO membrane technology)
Reverse osmosis is also called reverse osmosis, and its core component is semi-permeable membrane-bio-selective permeable membrane, which only allows solvent molecules to penetrate. It is called reverse osmosis because it is opposite to the direction of natural osmosis (natural osmosis means that water permeates the membrane from the high-concentration liquid side to the low-concentration side). Due to the high operating pressure, the membrane needs excellent performance, generally imported materials.
Step 3 compare
Compared with the ultrafiltration water purifier, the water quality of the reverse osmosis water purifier is cleaner and safer, which can remove all kinds of harmful impurities and metal ions in the water, and the water has a good taste, which can reduce the hardness of the water, and it is not easy to produce scale after the container is boiled.
The disadvantages of reverse osmosis water purifier are that it needs water pump and electricity, has electrical safety problems, many joints, high water pressure, relatively high failure rate and water leakage probability, complex structure and high cost. Moreover, its water output is difficult to reach the ultrafiltration water purifier, which will produce more wastewater. In terms of environmental protection and energy saving, reverse osmosis water purifier is far less than ultrafiltration water purifier.
