What is the difference between ultrafiltration and reverse osmosis water purifiers?

At present, most of the water purifiers on the market are reverse osmosis (RO) or ultrafiltration (UF) water purification products. Their water purification efficiency is much higher than other types of water purification products, and they are more in line with people's expectations for water purification effects. .
Difference 1: Water purification effect
In fact, the structure of ultrafiltration and reverse osmosis water purifiers is roughly similar. They are equipped with PP cotton, activated carbon and other coarse filter elements in the first half of the ultrafiltration membrane and reverse osmosis membrane. The final gap lies in the ultrafiltration membrane and reverse osmosis membrane. The membrane filtration performance. Generally speaking, the filtration accuracy of ultrafiltration water purifiers is roughly 0.01-0.1 microns, while the filtration accuracy of reverse osmosis membranes can reach 0.0001 microns, which is like a sieve with a pore size for comparison. The accuracy is higher.

As far as the filtering effect is concerned, the ultrafiltration water purifier can remove rust, sediment, bacteria, viruses, residual chlorine, different colors and odors and heavy metal substances in the water for you, while the reverse osmosis water purifier can further filter out the water. And harmful metal ions, but the calcium and magnesium ions needed by the human body will also be discharged with the waste water. The output of RO reverse osmosis water purifier is almost pure water, and it can even desalinate water and sea water.
　　 Difference 2: Installation complexity
The reverse osmosis water purifier works by increasing the osmotic pressure to achieve the principle of reverse movement of pure water against the natural osmosis direction. It needs high water pressure to "push", so mainstream reverse osmosis water purifiers can work normally with a booster pump. Reverse osmosis water purifiers need to be connected to the mains before they can be used, and the booster pump will increase the noise of the water purifier.
　Ultrafiltration water purifier is a physical filtration. Ultrafiltration water purifier can filter water normally without pressurization in areas where the water pressure reaches the standard. In addition, some ultrafiltration water purifiers are only suitable for the filtration of the conforming single-tube structure filter element, and the space occupation and installation conditions are lower.
Difference 3: Outlet flow
　　 If there is no pressure, RO reverse osmosis water purifier will not even produce pure water for you, and its fine filtering structure will greatly reduce the flow rate of the water.
Ultrafiltration does not need to worry about the flow rate. They produce about 1.5L of water per minute. In addition, there are some large flow reverse osmosis water purifiers above 400GPD on the market with a flow rate of about 1.2L per minute. If the water consumption is large, you should look at the flow rate This key value.
