1、 Equipment Overview

Reverse osmosis, abbreviated as RO, is a membrane separation technology developed in the 1960s. Its principle is that raw water passes through a reverse osmosis membrane under high pressure, and the solvent in the water diffuses from high concentration to bottom concentration to achieve separation, purification, and concentration. Due to its opposite direction of permeation from nature, it is called reverse osmosis. Reverse osmosis can remove bacteria, viruses, colloids, organic matter, and over 98% of soluble salts from water. This method has the characteristics of low operating cost, simple operation, high degree of automation, and stable effluent quality. Compared with other traditional water treatment methods, it has obvious advantages and is widely used in various water treatment related industries. Figure 1 shows the structure of the reverse osmosis membrane.

2、 Basic principles of reverse osmosis:

Reverse osmosis is a method of reversing the natural process of permeation. Permeation and reverse osmosis are achieved through a semi permeable membrane. When two solutions of different concentrations are separated by a semi permeable membrane, the solvent of the dilute solution will pass through the semi permeable membrane and enter one side of the solution. This phenomenon is called permeation. When an external pressure is applied on the concentrated solution side, the permeation rate will decrease. When this pressure increases to a certain value, the permeation process stops and reaches the so-called permeation equilibrium. The external pressure required for the equilibrium state is called osmotic pressure. When the pressure on the concentrated solution side continues to increase, that is, when the applied pressure is greater than the osmotic pressure, the solvent will reverse its original permeation direction and enter the dilute solution side through the semi permeable membrane from the concentrated solution side. This phenomenon is called reverse osmosis. Figure 2 is the schematic diagram of reverse osmosis.

In a water purification system, pressure is applied to a concentrated solution to counteract osmotic pressure, forcing water from the concentrated solution through a reverse osmosis membrane and collecting it to obtain pure water.
