Technical Field

Background
The principle of reverse osmosis desalination is that at a certain temperature, a semipermeable membrane which is easy to permeate water and difficult to permeate salt is used for separating fresh water from salt water (as shown as a in figure 2), the fresh water moves towards the salt water through the semipermeable membrane, and as the liquid level of the salt water side of a right chamber rises, a certain pressure is generated to prevent the fresh water of a left chamber from moving towards the salt water side, and finally equilibrium is reached, as shown as b in figure 2. The equilibrium pressure at this time is called the osmotic pressure of the solution, and this phenomenon is called the osmotic phenomenon. If an external pressure exceeding osmotic pressure is applied to the brine side of the right chamber (as shown in c of fig. 2), water in the brine solution of the right chamber moves to the fresh water in the left chamber through the semipermeable membrane, so that the fresh water is separated from the brine, and the phenomenon is opposite to the osmosis phenomenon and is called reverse osmosis phenomenon; it is known that reverse osmosis desalination is based on the permselectivity of ① semipermeable membranes, i.e., selectively permeable to water but impermeable to salt; ② The applied pressure of the brine chamber is greater than the osmotic pressure of the brine chamber and the fresh water chamber, and provides the driving force for the water to move from the brine chamber to the fresh water chamber.
