Ultrafiltration membranes and reverse osmosis water purifiers are often asked which is better. Now I will make a simple comparison for you. First of all, let's talk about ultrafiltration membranes.
Ultrafiltration water purifier: Ultrafiltration membrane is the core of Ultrafiltration water purifier. The pore size of Ultrafiltration membrane ranges from 0.1 to 0.111 microns. Bacteria, sediment, macromolecule organic matter and rust in water can be intercepted by ultrafiltration membrane. However, soluble odors, pigments, organic matter and inorganic matter in water can pass through the membrane together with water molecules. Ultrafiltration water purifier can not filter the residual chlorine in the water, and the boiled water may also produce scale.
Reverse osmosis water purifier: The principle of reverse osmosis is a popular method of water purification in the world. The core filter element of reverse osmosis water purifier is the reverse osmosis membrane. Its pore size is only 0.0001 micron. Even small viruses have a diameter of 0.2 micron, so they can not pass through the reverse osmosis membrane. In addition, heavy metals, inorganic salts, organic matter and bacteria dissolved in water can not pass through reverse osmosis membranes. The water through reverse osmosis membrane can reach the standard of direct drinking.
The advantages and disadvantages of ultrafiltration water purifier and reverse osmosis water purifier are compared.
The filtered water quality of reverse osmosis water purifier is safe, it can remove all kinds of harmful substances in water, and it can reduce the hardness of water without scaling. But the power consumption is relatively high, and there are more joints, complex structure and high price.
In contrast, the ultrafiltration water purifier consumes less electricity, has fewer joints, has simple structure and low price. But it can not effectively remove the chemical pollutants in water, and can not reduce the hardness of water, will produce scale.
