The reverse osmosis system is an important component of the reverse osmosis system, and it is also an important component of the reverse osmosis system. Forming concentration polarization. In order to affect the effluent quality of water treatment reverse osmosis equipment, in addition to considering the process design of water treatment equipment, improvement measures need to be taken during equipment operation.

1. Methods to increase traffic

We can use measures commonly used in the chemical industry to increase unrest. That is to say, try to increase the linear velocity of the fluid flowing through the membrane surface. In order to shorten the adsorption time of solutes, it is difficult for solutes to be adsorbed when the flow rate increases.

2. Filling method

For example, 29? Place a 100um sphere into the liquid to be treated and allow it to flow through the reverse osmosis system to reduce the thickness of the membrane boundary layer and increase permeability. Granular materials can be made of glass or methyl methacrylate. In addition, for tubular reverse osmosis systems, micro sponge balls can be added to the feed liquid. However, for the plate frame and wrapped film components, in other words, the method of adding fillers is not suitable, mainly due to the risk of blockages in the flow path.

3. Pulse method

A pulse generator has been added in the process of water treatment reverse osmosis equipment. The pulse amplitude and frequency are different. In general, the larger the amplitude or frequency, the greater the flow passing through. Stirring blades are widely used in various experimental equipment, and experience has shown that there is a linear relationship between mass transfer coefficient and stirring speed.

4. Install the turbulence booster

Turbulent propellants are barriers that can increase flow patterns. For example, for tubular parts, spiral baffles are installed inside. Plate or membrane components can be lined with a mesh to promote turbulence. This turbulence promoting agent has a good effect.

5. Add dispersants and scale inhibitors

To prevent scaling of the reverse osmosis membrane in water treatment reverse osmosis equipment, sulfuric acid or hydrochloric acid can be added to adjust the pH value. However, the corrosion and leakage of the acid system have caused trouble for operators. Therefore, scale is usually added to water treatment systems to maintain normal operation.
