The difference between UF membrane and RO membrane for bottled water

 

"Ultrafiltration" and "RO reverse osmosis" are believed to be familiar to everyone. These two bottled water treatment systems are currently the most common bottled water treatment methods on the market. 

The ultrafiltration membrane water treatment system is naturally very convenient. First of all, its cost is low, and there is not much waste water during use, and it does not need to be turned on. In this way, if the water quality in your area is good, and there is not much scale after the water source is boiled, it means that there are fewer metal ions in the water, and there is no problem at all in choosing an ultrafiltration membrane water treatment system. However, the ultrafiltration membrane water treatment system does not have the function of purifying metal ions in water. The ultrafiltration membrane can properly retain beneficial mineral elements, especially in areas rich in water quality mineral elements, which are especially suitable for bottled mineral water.

If your local source water is not good, there will be a lot of scale after boiling. At this time, it is very appropriate to choose a reverse osmosis bottled water treatment system to make purified water.

Purification effect

It can remove large particles of impurities such as rust and sand, and retain an appropriate amount of natural minerals

Removes almost all impurities from water, including harmful substances and natural minerals

 

The main difference is the huge difference between wastewater generation and water quality control. RO reverse osmosis technology is the one with the highest filtration precision. With a filter pore size of only 0.0001 microns, it can almost intercept all impurities in water, and the desalination rate can reach between 95-99%. Rate. Even tap water cannot pass through normally. It needs to be plugged in and use the strong pressure of the booster pump to squeeze the water molecules. All impurities are trapped outside the RO membrane, so a certain proportion of waste water will be generated in this process, and finally nearly H²O will be obtained. pure water. The bottled purified water we often buy is realized using this technology.

At the same time, the price of the reverse osmosis membrane water purifier is relatively high, and the cost issue is also a link that we need to consider. The reverse osmosis membrane water purifier has a good purification effect on water. The reverse osmosis membrane water purifier can be purified by electrolysis, etc. The method thoroughly purifies the metal ions in the water, so that we can drink the purest water. However, this reverse osmosis membrane water purifier has a disadvantage that it will purify almost all beneficial minerals in the water.

Therefore, when we choose a bottled water treatment machine, we need to decide whether to choose UF membrane or RO membrane according to the local raw water quality and our actual needs.
