Foam separation is a
chemical process which falls into a category of separation techniques called "
Adsorptive bubble separation methods".
[Adsorptive bubble separation methods, R. Lemlich (1968) Industrial and Engineering Chemistry, Vol. 60 (10) 16-29 ] It is further divided into
froth flotation and
foam fractionation Foam fractionation is a chemical process in which hydrophobic molecules are preferentially separated from a liquid solution using rising columns of foam. It is commonly used, albeit on a small scale, for the removal of organic waste from aquariums ...
. Foam separation is essential in order to prevent contamination of fermentation medium through the foam by external microbes.
