Changing the temperature, filtering and removing floating substances, making the container open, removing mechanical foaming factors (avoid strong boiling, shaking, decompression, and splashing), and removing bubbles that are easy to foam The solute, etc. is the physical method.

Adding a foam suppressant, feeding defoamer, removing foaming substances by adsorption, precipitation, and chemical reactions, adjusting the pH and HLB values, and adding substances that can eliminate foam stability are chemical methods.
