What is reverse osmosis process?

       Reverse osmosis processuses pressure as the driving force and uses the selectivity of reverse osmosis membranes to only permeate water but not solutes to extract pure water from a water body containing various inorganic, organic, and microorganisms. The reverse osmosis membrane has a pore size of less than 10 angstroms (1 angstrom is equal to 10-10 meters), and has a strong screening effect. Its salt rejection rate is as high as 99%, and the sterilization rate is greater than 99.5%. It can remove impurities such as inorganic salts, sugars, amino acids, bacteria and viruses in the water. If based on the quality of raw water and produced water, after proper design, RO is the most economical and effective method for purifying tap water, and it is also the best pretreatment method for ultrapure water systems.
