Water purifier filter element big reveal!How to choose RO membrane and ultrafiltration？

With the increasing demands of people's lives, the penetration rate of home water purifiers is also increasing。

At present, most of the water purifiers on the market are reverse osmosis or ultrafiltration water purification products, their water purification efficiency is far more than other kinds of water purification products, and the technology and price are more suitable for home use。

However, many people are entangled in the choice of ultrafiltration or RO reverse osmosis water purifier, let's talk about the main differences between the two types of water purification products, perhaps you can choose to more suitable for your own water purifier。

Difference one: RO reverse osmosis water purification effect is better

In fact, the structure of ultrafiltration and reverse osmosis water purifiers is similar。They are equipped with PP cotton, activated carbon and other coarse filter elements on the upper half, and the final difference is the filtration capacity in ultrafiltration membrane and reverse osmosis。

The filtration accuracy of ultrafiltration water purifier is about 0.01-0.1 micron, reverse osmosis membrane filtration accuracy of up to 0.0001 microns, which is like the size of the aperture of the sieve to do comparison, obviously smaller hole spacing sieve filtration accuracy is higher。

In terms of filtration effect, ultrafiltration water purifier can remove rust, sediment, bacteria, viruses, residual chlorine, heterochromic odor in the water, and reverse osmosis water purifier can further filter out heavy metals (such as mercury, lead, copper, zinc, inorganic arsenic), but the calcium and magnesium ions required by the human body are also discharged with the wastewater。

So the output of RO reverse osmosis water purifier is almost pure water, and the filtration effect is better than ultrafiltration。

Difference 2: RO reverse osmosis water purifier requires electricity

Reverse osmosis water purifier realizes the reverse movement of pure water against the natural direction of osmosis by increasing osmotic pressure。It requires high water pressure to "push", because China's tap water pressure is small, so the RO reverse osmosis water purifier to work normally with a booster pump, so many reverse osmosis water purifiers need to be connected to the main power supply。

Ultrafiltration water purifiers are physical types of filtration。Ultrafiltration water purifiers can filter purified water, usually without pressure, in areas where the water pressure is up to standard。

Difference 3: The discharge flow of ultrafiltration water purifier is larger

Without pressurization, RO reverse osmosis water purifiers will not even produce pure water for you, and their fine filtration structure will greatly reduce water flow。The greater the amount of RO membrane water, the higher the water production value。

Ultrafiltration doesn't have to worry about flow。Their water output is usually 1.5 liters per minute。If the water consumption is large, the water flow should be considerable。

Difference 4: RO reverse osmosis water purifier has wastewater rate

Because some residual substances (such as calcium carbonate, calcium sulfate, and silicon) on the surface of the RO film will be deposited on the surface of the reverse osmosis film, in order to prevent the RO film from clogging, it is necessary to constantly wash the RO film with water。

So if you want to get pure, healthy water, you have to sacrifice a certain percentage of wastewater。The wastewater of the ultrafiltration water purifier is very small, but the frequency of replacing the filter element is more frequent than that of the reverse osmosis RO membrane。

Difference five: the different scope of application of the two water purifiers

If your home is in a harsh environment with serious water pollution, be sure to choose RO reverse osmosis water purifier (water purifier)。The purification effect is very good, very thorough, its filtration accuracy is very high, only allows water molecules to pass through, can effectively remove the water rust, sediment, macromolecular organic matter, heavy metals, bacteria, viruses, etc., the effluent is pure water。

However, since RO water purifiers need to use electricity and use more water, the cost will be a little higher。

If the water quality is not too bad, ultrafiltration water purifier will do。Ultrafiltration water purifier can remove rust, sediment, macromolecular organic matter, bacteria, viruses, etc., pure physical filtration, no electricity, only need tap water pressure enough。

Whether it is RO reverse osmosis water purifier or ultrafiltration water purifier, they all have advantages and disadvantages。In the era of polluted water resources, safety is our first concern。Of course, if you want to buy a water purifier suitable for your own, the most important thing is to get the right water purification effect according to the water quality of your location。
