Ultrafiltration water purifier and RO (reverse osmosis) pure water machine are two common water treatment equipment, and they have some differences in principles, filtration effects, and applicable scenarios.
working principle:
Ultrafiltration water purifier: Ultrafiltration water purifiers use ultrafiltration membranes to remove suspended solids, bacteria, viruses, colloids, and large organic molecules in water through physical isolation. Its working principle is similar to a sieve, allowing only smaller molecules and solutes to pass through while filtering out larger particles and substances.
RO Pure Water Machine: RO Pure Water Machine uses a semi permeable membrane to remove dissolved salts, organic substances, and trace suspended particles from water through reverse osmosis process. Its working principle is to drive water through high pressure, causing water molecules to reverse osmosis through the membrane, thereby filtering out solutes and impurities and producing pure water.
Filtering effect:
Ultrafiltration water purifier: Ultrafiltration water purifier can remove large suspended particles, bacteria, viruses, colloids, and organic matter in water, but its removal effect on soluble salts and small molecule substances is poor. Generally speaking, the pore size range of ultrafiltration water purifiers is between 0.01 micrometers and 0.1 micrometers.
RO Pure Water Machine: RO Pure Water Machine has a high filtration effect and can remove dissolved salts, organic substances, bacteria, viruses, and trace suspended particles from water. The pore size of RO membranes is very small, typically around 0.0001 micrometers (also known as 1 nanometer).
Applicable scenarios:
Ultrafiltration water purifier: Ultrafiltration water purifier is suitable for situations with relatively low water quality requirements, and can remove larger particles and some large molecular organic matter. It is commonly used in drinking water purification, water treatment, and pretreatment processes in homes, offices, and commercial places.
RO pure water machine: RO pure water machine is suitable for applications with high water quality requirements, which require the removal of dissolved salts, organic substances, and trace impurities. It is commonly used in fields such as laboratories, pharmaceuticals, electronics, beverage industry, and purified water supply that require high-purity water.
It should be noted that the RO pure water machine has a good effect in removing soluble salts and organic substances, but it also filters out some minerals and trace elements in the water at the same time. Therefore, for certain specific applications (such as drinking water), mineralization or adding appropriate amounts of minerals may need to be considered to meet the needs of the human body. The ultrafiltration water purifier relatively retains the minerals in the water.
