Description

Technical Field

[0001] The present application relates to the field of nanofiltration membranes, and in particular to reverse osmosis nanofiltration membrane assemblies. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation process that uses a pressure differential as the driving force to separate a solvent from a solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent permeates in the opposite direction of natural osmosis. The result is permeate, the permeate, on the low-pressure side of the membrane, and a concentrated solution, the concentrate, on the high-pressure side. When reverse osmosis is used to treat seawater, fresh water is obtained on the low-pressure side of the membrane, while brine is obtained on the high-pressure side. Because it operates in the opposite direction of natural osmosis, it is called reverse osmosis. Depending on the different osmotic pressures of various materials, a reverse osmosis pressure greater than the osmotic pressure can be used, a process known as reverse osmosis, to achieve separation, extraction, purification, and concentration.
