Solid-liquid separation There are many methods that can be used. The following are some common methods:

1. Filtration interception: solid particles are intercepted through filter media, such as filter paper, filter cloth, filter screen, etc., so that liquid can pass through to realize solid-liquid separation.

2. Separation of specific gravity difference:

-Centrifugal separation: use centrifugal force to separate substances with different specific gravity. Centrifuge Such equipment will rotate at a high speed and generate strong centrifugal force to separate substances with different specific gravity.

-Gravity sedimentation: separation is realized by relative movement of particles and fluids based on gravity and density difference between particles and fluids. Gravity sedimentation is often used to separate dust particles from the air stream.

3. Temperature change separation: change the temperature of materials to make them change from solid to liquid or vice versa, so as to realize solid-liquid separation.

Other special separation methods, such as magnetic separation and electric field separation, realize solid-liquid separation through specific properties of materials, such as magnetism or electricity. Different solid-liquid separation methods are applicable to different materials and separation requirements, and appropriate methods need to be selected according to the specific situation.
