MEMBRANES

WHAT IS MEMBRANE?

membrane (Membrane) separation process principle

Membrane classification

Characteristics of membrane separation technology

(A) advantages

1.Low energy consumption Membrane separation does not involve phase change, low energy requirements, and distillation, crystallization and evaporation compared to a larger difference;

2.Is the separation condition mild and important for the separation of heat sensitive substances;

3.Easy to operate, compact structure, low maintenance costs, easy to automate.

(B) shortcomings

1.Membrane surface prone to pollution, resulting in reduced membrane separation performance, it is necessary to use the process to adapt to the membrane cleaning method;

2.Stability, resistance, heat resistance, solvent resistance is limited, so the use of limited;

3.Separate membrane separation technology has limited functionality and needs to be used in conjunction with other separation technologies.
