1.From the filtration principle of ultrafiltration membrane water purifier (UF) and RO water purifier, both of them filter water through polymer material membrane.
Remove impurities from water.

2. From the filtration accuracy of the ultrafiltration membrane and the RO membrane, the filtration accuracy of the two is different. The filtration accuracy of the ultrafiltration membrane is 0.01 microns,
The filtration accuracy of RO membrane is 0.0001 microns.

Tap water purified by ultrafiltration membrane can remove harmful impurities such as sediment, rust, colloid and bacterial microorganisms,
At the same time retain the original minerals and trace elements in the water.

After RO membrane filtration and purification, pure water with only water molecules left is obtained, which can not only effectively remove sediment, rust,
Colloids, bacterial and other harmful impurities, but also remove pesticides, heavy metals, etc. Olansi RO Water Purifier W4 (Reddot design awarded )in
There is also a trace element filter element after the RO membrane filtration, adding minerals and trace elements that are beneficial to the human body. The most special one is strontium.
Strontium balances the absorption of sodium and calcium in the body.

3.Ultrafiltration membrane water purifiers generally use the pressure of tap water to perform filtration without electricity. RO water purifier because the filtration accuracy is too high,
Filtering and purification cannot be achieved using the water pressure of the tap water itself, so it is generally required to be energized and pressurized to achieve purification and filtering of tap water.
In addition, RO water purifiers generally produce wastewater. Through the improvement and improvement of technology in recent years, the wastewater ratio of RO water purifiers has been reduced from 3: 1 to 2: 1 or 1: 1.
