High efficiency of reverse osmosis purification: The surface pore size of reverse osmosis membrane is generally less than 1nm, and it has a high removal rate for the vast majority of inorganic salts, dissolved organic compounds, dissolved solids, organisms, and colloids.

Low energy consumption: Pressure is the main driving force in the reverse osmosis separation process, without undergoing phase transition through intensive energy exchange.

Low operating cost: Reverse osmosis does not require a large amount of precipitants and adsorbents.

Environmentally friendly: The design and operation of reverse osmosis separation engineering are simple, and the purification efficiency is high.

High filtration accuracy of ultrafiltration system: The filtration accuracy of ultrafiltration membrane can reach 0.01 microns, which can filter out harmful substances such as rust, sediment, colloids, bacteria, etc. in water.

Large water output: The ultrafiltration water purifier uses water pressure for pure physical filtration, resulting in a larger and faster purified water output.

Long service life: The ultrafiltration water purifier filter element can automatically flush and clean, extending the service life of the filter element.

The combined application of reverse osmosis and ultrafiltration

In practical applications, reverse osmosis and ultrafiltration technologies are often combined to fully leverage their respective advantages. Usually, ultrafiltration technology, as a pretreatment step of reverse osmosis technology, can remove most of the suspended solids, colloids, and large organic molecules in water, thereby reducing the burden on the reverse osmosis membrane and extending its service life. Meanwhile, reverse osmosis technology can further remove dissolved solids, inorganic salts, and microorganisms from water, ensuring that the effluent quality meets production requirements.

By reasonably combining these two technologies, it is possible to ensure that the effluent quality meets production requirements while reducing operating costs and environmental impact. In addition, enterprises should also pay attention to the maintenance and management of equipment to ensure its long-term stable operation.
