Abstract

The present invention concerns in one aspect a separator for separating the gas and liquid phases of a foam and, in another aspect, a foam reducing apparatus. The separator comprises a first side and a second side and having through-flow means provided therein for permitting a foam or a foam phase to pass from the first side to the second side, the separator further comprising at least one foam contacting surface having a low surface energy, and means for recovering at least one separated foam phase from the foam. The foam reducing apparatus comprises a low surface energy material and means for contacting foam, when said foam is input to the foam reduction apparatus, along a surface of said low surface energy material. The separator and the foam reducing apparatus may be used independently or in combination to good effect to more efficiently disrupt foam to provide separate gas and liquid phases.
