Application of reverse osmosis membrane technology in pharmaceutical industry

With the development of pharmaceutical industry, the water quality of pharmaceutical water is also gradually increased, the traditional water process such as ion exchange method has been far from meeting its requirements, in order to meet the needs of this development, green water treatment company has advanced , Effective water purification technology – reverse osmosis membrane technology used in the pharmaceutical industry water treatment system. Reverse osmosis membrane separation principle and performance, nature has such a natural phenomenon, when a semi-permeable membrane will be a thin solution (such as pure water) and pure solution (such as salt water) separated, the thin solution will penetrate into the thick solution The corresponding osmotic pressure is maintained. This phenomenon is called osmotic phenomenon. For example, if the pressure is greater than the osmotic pressure in the thick solution, the strong solution will permeate to the dilute solution side. This phenomenon is called reverse osmosis phenomenon. Technical semi-permeable membrane technique is internationally recognized high-tech, it by the role of external pressure so that the solvent solution through the semi-permeable membrane and retain some of the solute, it is an effective means of separation, concentration and purification. Reverse osmosis membrane surface pore size generally around 10A, it can effectively remove particles, colloids, bacteria, pyrogens and organic matter and most of the ions. The current reverse osmosis membrane material is mainly aromatic polyamide low-pressure composite membrane and advanced ultra-low pressure composite membrane.
