RO (Reverse Osmosis) reverse osmosis technology is the use of pressure gauges difference as the driving force of membrane separation filter technology from aerospace technology research in the United States in the 1960s gradually converted to civilian use, has been widely used in scientific research, medicine, food, beverage, such as desalination.
RO reverse osmosis membrane pore size as small as a nanometer (1 nm = 10-9 m), under certain pressure, H2O molecules through the RO membrane, the source water, inorganic salts, heavy metal ions, organics, colloids, bacteria, viruses, etc. impurities can not be through the RO membrane, so that through pure water and not available through the condensed water strictly separate.
General tap water through the RO membrane filtration of pure water conductivity 5μs/cm (RO membrane filtration water conductance = water conductivity × desalination rate, the general import of the reverse osmosis membrane desalination rate can reach 99% or more, five years running requirements on water conductivity is relatively high, can be used two reverse osmosis, simple processing, the electric conductivity of less than 1μs/cm), in line with national laboratories and three water standards to ensure that more than 97%. After the atomic-level ion exchange column loop filter, the water resistivity can be achieved 18.2Mcm exceed National Laboratory, a water standard (GB 6682-92).
Preparation of space and water, pure water, distilled water; liquor manufacturing and reduce the degree of water; the preliminary preparation of the medicine, electronics and other industries with water; chemical process of concentration, separation, purification and distribution of water preparation; boiler feed water desalination water softener; sea water, bitter water desalination; papermaking, electroplating, printing and dyeing industry, water and wastewater treatment. Polymer membranes for membrane separation technology as a new, highly efficient fluid separation unit operation, rapid development has made remarkable 30 years, has been widely used in various fields of national economy.
