Nowadays more and more people are using water purifiers,but when we are choosing the right water purifiers for our families,we always have some blind spots and doubts. The main problems are concentrated on reverse osmosis membrane water purifiers and ultrafiltration membrane water purifiers.UF membrane vs ro membrane,then Which one should we choose? Both of these water purifiers have excellent water purification systems, which can meet the water purification standards. However, there are obvious differences between reverse osmosis and ultrafiltration.So What is the difference between a reverse osmosis and an ultrafiltration ? let's take a look.
①Difference between reverse osmosis filter element material and ultrafiltration filter element material
First of all, we look at the ultrafiltration membrane water purifier from the filter material.Ultrafiltration membrane water purifiers mainly use uf ultrafiltration membranes, and reverse osmosis water purifiers mainly use reverse osmosis membrane filters. The filter elements of these two water purifiers are totally different. The filter element of the reverse osmosis membrane water purifier can purify the water containing small molecules of impurities,such as some small gold particles can be purified, while the ultrafiltration membrane water purifier can only purify some large impurities in the water. The two types of water purifiers The effect of the degree of water purification is different.
②Difference between reverse osmosis purification rate and ultrafiltration purification rate
In terms of purification rate,the filtration accuracy of the ultrafiltration membrane water purifier is about 0.1μM. Under this accuracy,the rust suspension and bacterial macromolecule organic matter in the water can be filtered well, while the filtration of the reverse osmosis membrane water purifier The accuracy is more than 100 times that of the ultrafiltration membrane water purifier.It can filter inorganic salts, heavy metals, ions, viruses and other substances in the water, so it is very clean and transparent.The water filtered by the reverse osmosis membrane can be called pure water,but the ultrafiltration membrane cannot.
③Difference between reverse osmosis Filter life and ultrafiltration filter life
Compare the service life of the two machines.The service life of the ultrafiltration membrane can reach about one year,while the reverse osmosis membrane can be used for two years.The main reason for this difference is that the ultrafiltration membrane water purifier does not need electricity,it mainly purifies water through pure filtration,and produces less waste water. Therefore, in the purification process,there will be more impurities that affect the filtering effect of the water purifier.The reverse osmosis membrane water purifier is plug-in type and will produce a lot of waste water after purification. Because the waste water discharges more impurities, the service life is longer. However, the price of reverse osmosis membrane water purifiers is significantly higher than that of ultrafiltration membrane water purifiers.
④Difference between the water taste of reverse osmosis and ultrafiltration
The taste of water purified by these two types of water purifiers is very different as well, because the ultrafiltration membrane water purifier can only purify the water to a molecular level, while the reverse osmosis membrane water purifier can reach the ionic level. The water filtered by the ultrafiltration membrane water purifier generally has a certain degree of scale, and the taste is not as soft as the water purified by reverse osmosis membrane water purifier.So a reverse osmosis membrane water purifier is a better choice for Families with higher requirements on the taste of drinking water.
⑤Difference between Energy saving of reverse osmosis and ultrafiltration
Ultrafiltration membrane water purifiers are more energy-efficient than reverse osmosis membranes. In the water purifier, because the ultrafiltration membrane water purifier does not require electricity, it filter and purify the water with the pressure of tap water, which can save a lot of energy. However, reverse osmosis membrane water purifiers are different. Because the small holes on the filter element are small, the pressure of the reverse osmosis membrane water purifier needs to be increased by voltage to achieve the water filtration process.
Although it consumes more electricity, the technology will be further strengthened in the future, and it will basically not cost too much electricity. Besides, the ultrafiltration membrane water purifier's purification efficiency is much higher than that of the reverse osmosis membrane water purifier. Because the ultrafiltration membrane water purifier does not require electricity, and the holes on the filter element are large, it will naturally be more effective in the water purification process. quick. Therefore, if the domestic water quality is not high, you can choose an ultrafiltration membrane water purifier. However, the efficiency of reverse osmosis membrane water purifier is not as good as the ultrafiltration membrane water purifier,because the reverse osmosis membrane water purifier requires electricity due to the small holes in the filter element.
In conclusion, the choice of water purifier is completely determined by the buyer’s environment. Some in big cities have urban underground water supply. The water quality is relatively good.So ultrafiltration is a better choise.However, in some Places with poor water quality you can choose reverse osmosis water purifier.
