Reverse osmosis Technology

Sep 22, 2017

When the same volume of dilute solution and concentrated solution were placed on both sides of a container, the middle with a semipermeable membrane barrier, dilute solution of the solvent will naturally pass through the semipermeable membrane, to the concentrated solution side, concentrated solution side of the liquid Surface than the dilute solution of the liquid level above a certain height, the formation of a pressure difference, to osmotic equilibrium state, this pressure difference is osmotic pressure. If a pressure greater than the osmotic pressure is applied to the concentrated solution side, the solvent in the concentrated solution flows to the dilute solution, and the flow direction of the solvent is opposite to that of the original infiltration. This process is called reverse osmosis.
