An apparatus for the foaming of organic components in sea water or sweet water has above a pump or other bottom part capable of forcing water upwardly an upstanding aeration vessel in which a mixture of air and water induces foaming, the excess water passing over a weir from this vessel while the bubbles ascend to a riser made up of a multiplicity of wall parts, e.g. a multiplicity of thin tubes or concentric tubes with partitions dividing them into segments, such that the bubbles remain substantially intact without bursting as they rise and capillary displacement of water is precluded. The foam can be collected in a receptacle around this riser. |
