Technical Field

Background

Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses a pressure differential as a driving force to separate a solvent from a solution. The feed solution on one side of the membrane is pressurized and when the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural osmosis. Thereby obtaining a permeated solvent, i.e., permeate, at the low pressure side of the membrane; the high pressure side yields a concentrated solution, i.e., a concentrate.

In the existing reverse osmosis purification structure for drinking water, a flow dividing structure for concentrated water and fresh water has certain defects, and an adaptive related structure is not made according to different flowing characteristics of the fresh water and the concentrated water, so that the concentration degree of the concentrated water is low when the concentrated water is led out, and the purity of fresh water output is influenced, and therefore corresponding improvement is needed.
