WebMore or less antifoam may be needed depending on the contaminant loading. Usually antifoams should be fed to the surface of the liquid, especially if solids concentration is high. The product is most efficient if system turbulence will help spread the antifoam to the desired areas. The feed point is critical to the success of any antifoam product.

WebAntifoam chemicals work by reducing the surface tension of the liquid films that form the bubbles within the foam, causing them to more rapidly break down and dissipate. However, there are potential adverse effects—such as toxic effects on metabolism, lowering of cell gas uptake, and reduction of yield—from the addition of antifoam chemicals. WebDefoamers work by forcing oil droplets into the water-air boundary layer of a foam lamella, where they spread. The defoamer destroys the foam lamella. If a hydrophobic silica product is also dispersed in the oil, the oil droplets can penetrate the boundary layer far more quickly, making the defoamer significantly more effective.
