Web15 hours ago · The terms anti-foam (or antifoam) agent and defoamer are often used interchangeably, but they in fact differ. Defoamers eliminate existing foam, while anti-foamers prevent the formation of more foam. Antifoams are typically added to the foaming solution before foam formation and act to avoid excessive foam formation. WebAug 1, 2015 · The causes of foaming in biogas reactors have been previously investigated, identifying the feedstock composition, the organic overload, and the presence of specific microorganisms as the main causes for foam formation (Dalmau et al., 2010, Kougias et al., 2014c, Moeller et al., 2015).
