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; these units are known as "protein skimmers". However it has much broader application in the chemical process industry and can be used for the removal of surface active contaminants from waste water streams in addition to the enrichment of bio-products.

Famous quotes containing the word foam:

    Only the white, tremendous foam of the street has any importance,
    The new white flowers that are beginning to shoot up about now.
    John Ashbery (b. 1927)
