Reverse osmosis: The technology of preparing pure water by reverse osmosis is a new technology developed in the 1960s. Because of its simple operation process, high efficiency of salt removal and heat removal, and relatively economical. “United States Pharmacopoeia” began to include this method from the 19th edition, as one of the legal methods for preparing water for injection.
Mechanism: Reverse osmosis is the reverse process of osmosis, which refers to the process of forcing the solvent component in the solution to pass through an appropriate semi-permeable membrane by means of a certain thrust (such as pressure difference, temperature difference, etc.) to retain a certain solute component.
