RO reverse osmosis water purifier is different from the ultrafiltration mentioned above, it is generally called pure water machine and direct drinking machine in the market, which means it can provide absolutely pure water and drinking water directly. As we all know, even if the tap water from the city water plant is up to the standard when it leaves the factory, there will still be all kinds of harmful substances when it arrives at the household, such as the growth of bacteria, pipe dirt and residual bleach. All these limit that tap water cannot be drunk directly. So, how does the RO reverse osmosis water purifier remove these harmful substances and make it possible to drink directly? Next, Hua Benkun will briefly analyze the working principle and performance characteristics of the RO pure water machine.

Working principle of RO reverse osmosis water purifier

Working principle diagram of ro reverse osmosis water purifier

The core of the working principle of RO reverse osmosis water purifier is RO reverse osmosis membrane, and its mechanism is that when tap water flows through RO reverse osmosis device, a pressure difference is formed on both sides of RO reverse osmosis membrane, thus completely pure water molecules are filtered through osmosis membrane to the outlet pipe, while harmful components such as bacteria, sediment and rust are intercepted in the wastewater. Determine the reverse osmosis membrane decontamination capacity is its micro-pore size, the market qualified RO reverse osmosis filter pore size of less than 0.0001 microns, so that almost all the impurities in the water can be isolated from the osmosis membrane, so that the water out of the water is called pure water. The diagram above directly illustrates the working principle of RO reverse osmosis membrane.

Filter element structure of RO reverse osmosis water purifier

So, what is the structure of RO reverse osmosis water purifier (water purifier)?

RO reverse osmosis water purifier is different from other water purifiers in that the filter element of RO reverse osmosis water purifier should include at least the following filter elements: PP cotton filter, front activated carbon filter, rear activated carbon filter and RO reverse osmosis membrane filter. This is the most basic composition of pure water machine filter element, of course, there may be pure water machine will have more filter elements, or there are multi-stage filter elements.

Disadvantages of RO reverse osmosis water purifier

We can drink the water provided by the pure water machine directly, since there are such great advantages, there will be disadvantages. The pure water machine occupies a larger space compared with the ultrafiltration water purifier, and the water output is smaller. At the same time, it also needs to install power supply and consume a certain amount of electric energy.

In addition, there is a debate on the concept of health, that is, the RO reverse osmosis water purifier, because of its extremely small aperture, not only removes harmful substances, but also filters out minerals and other trace elements in the water, losing part of the activity of natural water, so in the field of nutrition, there is still a heated debate about the advantages and disadvantages of long-term drinking water. Must be separated, but purely from the removal of harmful substances, RO reverse osmosis water purifier is undoubtedly the most powerful.

RO reverse osmosis water purifier is suitable for people

Because the effluent of RO reverse osmosis water purifier can be drunk directly, it is more suitable for people who like to drink directly. In addition, some special people, such as stone patients, should not drink water with high hardness, and it is also very necessary to use RO reverse osmosis pure water machine.
