With the aggravation of water pollution, people pay more and more attention to drinking water safety. Reverse osmosis water purifier (RO water purifier), as an efficient water treatment equipment, has gradually become a popular choice for home and commercial water purification with its excellent purification function and many advantages.
Purification function
Reverse osmosis water purifiers use reverse osmosis membrane technology to squeeze water molecules out of the solution through high pressure to filter out impurities and pollutants in the solution. The pore size of the reverse osmosis membrane is extremely small, only 0.0001 micron, and can effectively remove dissolved salts, heavy metals, bacteria, viruses and other harmful substances from the water. The following are its main purification functions:
Removal of dissolved solids: RO water purifiers can effectively remove dissolved solids from water, such as heavy metals (lead, mercury, arsenic, etc.), minerals and chemical pollutants, making the water more pure.
Remove microorganisms: Reverse osmosis membrane can filter bacteria, viruses and other microorganisms in water to ensure the health and safety of drinking water.
Removal of organic pollutants: Reverse osmosis technology can effectively remove organic compounds and chemical pollutants in water, such as pesticide residues and industrial pollutants.
Advantages
Efficient purification: The filtration accuracy of the reverse osmosis water purifier is extremely high, which can remove almost all pollutants in the water and provide pure drinking water.
Improve taste: By removing odors and impurities from the water, reverse osmosis water purifiers can significantly improve the taste of drinking water, making the water more refreshing and sweet.
Health protection: Reverse osmosis water purifiers can filter out harmful substances in water, reducing the potential health threats of heavy metals and organic pollutants in drinking water.
Widely used: suitable for home, office, hospital, laboratory and other occasions, especially for the environment with high water quality requirements.
Comparison with ultrafilters
Filtration accuracy: The filtration accuracy of reverse osmosis water purifiers is higher than that of ultrafilters. The RO membrane has a pore size of 0.0001 micron, while the ultrafiltration membrane has a pore size of about 0.01 micron. As a result, RO water purifiers are able to remove a greater variety of tiny contaminants and dissolved solids.
Retain minerals: Ultrafilters retain the beneficial minerals in the water, while reverse osmosis water purifiers remove most of them. This makes the water purified by the ultrafilter closer to natural water, but the water provided by the RO water purifier is purer.
Cost of use: Reverse osmosis water purifiers usually require electric power and have a high wastewater ratio, which increases the cost of use. The ultrafilter generally does not require electric drive, low wastewater rate, energy saving and environmental protection.
Maintenance and replacement: The filter replacement cycle of the reverse osmosis water purifier is longer, but the replacement cost is higher. The filter element of the ultrafilter is replaced more frequently, but the replacement cost is lower.
Reverse osmosis water purifier has become the leader in modern water treatment equipment with its excellent purification function and diversified advantages. By comparing the ultrafilters, it can be seen that the two have advantages in filtration accuracy, mineral retention and use cost. The choice of water purifier should be determined according to the actual needs and water quality to ensure the safety and health of drinking water. Whether it is household daily drinking water, or commercial applications, reverse osmosis water purifiers can provide reliable water security.
