In today’s society, as people attach importance to healthy drinking water, water purifier has gradually become an indispensable part of family life. The core component of the water purifier – RO reverse osmosis membrane, is known as the “soul” of the water purifier. So, what is RO reverse osmosis membrane? How does it work? This article will provide you with a detailed analysis of RO reverse osmosis membrane of some common sense.
RO membrane and seagulls
Seagull body, there is a layer of film, the film is very precise, seawater inhaled by the seagull body, pressurized, and then by the pressure, the water molecules through, penetrate the film, into fresh water. The seawater containing impurities and highly concentrated salts is spat out of the mouth. The film in the seagull’s throat is the prototype of reverse osmosis membrane.
RO reverse osmosis membrane, full name Reverse Osmosis Membrane, is a use of pressure difference as a driving force, from the solution to separate the solvent membrane separation operation technology. Its principle is based on the reverse process of natural osmosis phenomenon, that is, when the same volume of dilute solution (such as fresh water) and concentrated solution (such as seawater or brine) are placed on both sides of a container, separated by a semi-permeable membrane, the solvent in the dilute solution will naturally pass through the semi-permeable membrane to the concentrated solution side of the flow until osmotic equilibrium is reached. However, in the RO reverse osmosis process, the external application of a certain pressure, so that the water molecules against the direction of natural osmosis, from the high concentration of solution to the low concentration of solution infiltration, so that the dissolved in the water impurities, bacteria, viruses, and other harmful substances are retained on the other side of the membrane, resulting in pure water.
RO reverse osmosis membrane, the best water purification effect
RO reverse osmosis water purifier, is the safest drinking water program. This kind of filtered water, is direct drinking water, for water purification, is a qualitative leap. Filtration effect, depending on the filter precision of the cartridge, filtration precision from strong to weak, in order: RO reverse osmosis > nanofiltration > ultrafiltration > microfiltration if not RO reverse osmosis technology, that is, with a 100-level filter, but also up to the filtration effect of drinking water. There are 2221 kinds of organic matter in water alone. Reverse osmosis membrane filtration precision of 0.0001 microns, that is, one millionth of a hair.
It can filter all the impurities in the water, can only allow water molecules to pass through.RO reverse osmosis membrane, generally 2 to 3 years to replace once can. As long as the RO reverse osmosis membrane can be used, the other membrane thrown away do not affect the filtering effect, the replacement frequency do not have to consider other cartridges, when the time to change out together on the line. In space, astronauts waste liquid recycling, processing into drinking water, is to use it.
When buying a water purifier Frizzlife WB99 Countertop Reverse Osmosis System, Alkaline RO Water Filter is your best choice. By combining carbon fiber, a 100 gallon RO membrane, and alkaline granules, the Frizzlife WB99-C Countertop Reverse Osmosis System effectively reduces more than 1,000 harmful contaminants.The Frizzlife Countertop RO System comes in a variety of dispensing volumes: 4 ounce, 8 ounce, 17 ounce, and continuous. Simply tap the screen to select the desired volume. The smart touch panel is sensitive and easy to operate. It displays the latest TDS results after each water production. In addition, this RO water filtration system will continue to monitor cartridge life and remind you to change your cartridge early. In addition, the water quality indicator will turn red if the filtered water in the kettle is more than 24 hours old. The user-friendly design takes the guesswork out of it.
Why is there wastewater in a real water purifier?
RO water purifiers will definitely produce wastewater. Wastewater discharge is the working characteristic of “RO membrane”. Don’t worry about the waste water, don’t think it’s a waste of water and money, only in this way, you can drink it safely and healthily. If your home water purifier does not produce waste water, then you should not be too happy. This is because your water purifier may be an ultrafilter, which can only be used for living, panning rice and washing vegetables, and is not suitable for direct drinking. Its effectiveness is worrying. Water purifier does not discharge waste water, is the “RO membrane” replaced by “ultrafiltration membrane”, so that the filtration effect is 100 times worse than the RO membrane. (Both precision value: 0.0001 micron and 0.1 micron) with ultrafiltration membrane, heating or limescale.
A water purifier, there will be a lot of cartridges, there are a few called a few levels of filtration. But play a key role in the cartridge is the RO membrane, the rest are dispensable, the biggest role is to protect the RO membrane, extend the life of the RO membrane. Therefore, the water purifier produces waste water, although it will waste some water, but it is a real guarantee of the health and safety of water quality.
