According to the principle of concentration polarization formation in the membrane separation process, it is known that reducing the thickness of the concentration polarization boundary layer and increasing the mass transfer coefficient of the solute can reduce the concentration polarization and increase the liquid permeability of the membrane. The weakening measures are as follows:
1. Select the appropriate membrane module structure.
2. Add a turbulent flow.
3, the flow of liquid cross-cut flow design.
4. The liquid flow is pulsed.
5, the liquid flow spiral.
6. Increase the flow rate of the feed solution.
7. Appropriately increase the temperature of the feed liquid to reduce the viscosity and increase the mass transfer coefficient.
