Comprehensive interpretation of the five-stage filtration system of Dongguan water purifier
Dongguan water purifier is developed based on the principle of reverse osmosis. Although the sparrow is small and complete, it uses RO reverse osmosis membrane separation technology to apply a certain pressure to the water to make water molecules and ionic mineral elements pass through the reverse osmosis membrane. , And most of the inorganic salts (including heavy metals), organic matter, bacteria, viruses, etc. dissolved in the water cannot pass through the reverse osmosis membrane, so that the permeated purified water and the impermeable concentrated water are strictly separated; reverse osmosis membrane The pore size is only 0.0001 microns, while the diameter of viruses is generally 0.02-0.4 microns, and the diameter of ordinary bacteria is 0.4-1 microns.
The first level: The pre-PP pre-filter is made of melt-blown polypropylene material that meets the FDA standards of the US Food and Drug Administration. The pore size is 5 microns. It is mainly used to grab suspended magazines, particles, sludge, etc. in the water.
The second level: GAC granular activated carbon filter is a granular high-efficiency adsorbent activated carbon that can absorb ethylene dichloride, bleach, pesticides, chlorine, odor, color, and other chemical poisons that are harmful to the human body.
The third level: Compressed activated carbon filter, which can further adsorb different colors, odors, residual chlorine, halogenated hydrocarbons and other harmful substances in the water. The long-life compressed activated carbon and high dirt holding capacity mesh structure make the filter element dual-functional Filtering effect.
The fourth level: US original DOW Dow reverse osmosis (RO) membrane elements, using the principle of hydraulic reverse osmosis to filter out bacteria, viruses, heat sources, pesticide pollutants, chemicals, heavy metals, etc. in the water, and remove the water that affects human health. Harmful substances, the drinking water produced is safe and healthy.
Level 5: The rear high-precision filter is made from the burning and pressing of pure natural coconut shell. After filtering, it can remove peculiar smell and improve the taste of drinking water.
It can not only remove water alkali and heavy metals, impurities, viruses, colloids and bacteria, but also remove organic matter, fluorescent substances, and pesticides that are harmful to the human body, so that you can boil water without water and alkali, and at the same time ensure the health of your family. The use of purified water can ensure the original juice and flavor of the food, and fully decompose the nutrients in the food, making it more suitable for human absorption. The pure water machine uses pure water in the humidifier or water heater to ensure that there is no alkali and better protect your household appliances.
