Chemical methods for foam elimination:
From a chemical perspective, methods for eliminating foam primarily include chemical reaction–based approaches and the addition of defoamers. The chemical reaction method involves introducing reagents—such as defoamers—that react with the foaming agents to form water-insoluble compounds, thereby reducing the concentration of surfactants in the liquid film and promoting foam rupture. However, this approach suffers from drawbacks, including uncertainty regarding the composition of the foaming agents and the potential formation of poorly soluble substances that can damage equipment. Today, the most widely used defoaming strategy across various industries is the addition of defoamers, which offer advantages such as high defoaming efficiency and ease of use. Nevertheless, identifying a suitable and highly effective defoamer remains crucial.
