A method and apparatus is provided for separating the liquid and non-liquid components of a foamy mixture. The apparatus comprises a filter means through which the liquid portion of the foam can pass and through which the gaseous or air component cannot pass, unless a pressure differential across the filter exceeds the bubble point of the filter. First means are provided to supply the foam to a first side of the filter means. Additional means are provided to remove the liquid component of the foam from the second side of the filter, and the gaseous component of the foam from the first side of the filter. A pressure differential is established between the two sides of the filter to cause the liquid component of the foam to pass through the filter; but the pressure differential across the filter is prevented from exceeding the bubble point of the filter to prevent the gaseous component of the foam from passing through the filter.
