The difference between reverse osmosis membrane and ultrafiltration membrane

1. Comparison of specific parameters of reverse osmosis membrane and ultrafiltration membrane

Second, the application characteristics of reverse osmosis membrane

1) It should have a high efficiency of salt rejection at high flow rates;

2) has high mechanical strength and service life;

3) can function at lower operating pressures;

4) can withstand the effects of chemical and biochemical effects;

5) It is less affected by factors such as pH and temperature;

6) The raw materials for molding are easy, the processing is simple, and the cost is low.

Third, the application characteristics of ultrafiltration membrane

1) No qualitative change will occur during the ultrafiltration process, and it can be stably operated at normal temperature;

2) The equipment is compact in structure, small in floor space and easy to operate;

3) The ultrafiltration separation process is simple and the equipment is highly automated;

4) can classify different molecular weight substances;

5) Water treatment technology with strong applicability to water quality and wide application range.

Fourth, the application range of reverse osmosis membrane

Power, petrochemical, steel, electronics, medicine, food materials, digital environmental protection and other fields, desalination of seawater and brackish water, boiler feed water, industrial pure water and electronic grade ultrapure water preparation, drinking pure water production, wastewater treatment and It plays an important role in the special separation process.

Five, the application range of ultrafiltration membrane

Pure water and ultrapure water preparation process as reverse osmosis pretreatment and ultra-pure water terminal treatment; industrial water used to separate bacteria, heat sources, colloids, suspended impurities and macromolecular organics; drinking water, mineral water purification; fermentation, Concentration, purification and clarification of enzyme preparation industry and pharmaceutical industry; concentration and separation of juice; separation, concentration and clarification of soybean, dairy, sugar industry, alcohol, tea juice, vinegar, etc.; industrial wastewater treatment and purification of domestic sewage Recycling; recovery of electrophoretic paint.
