    22-06-2015· Froth Flotation Frothers are chemicals used to strengthen the SURFACE TENSION of an air bubble. They do not create air bubbles. To demonstrate surface tension, fill a glass of water just prior to over flowing, you will notice that the surface of the water actually extends past the lip of the glass.

    Foam fractionation Wikipedia

    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
