SEPARATION OF MULTI-PHASE SYSTEMS

Multi-phase systems are treated to enhance separability of at least one phase by establishing the multi-phase system in predetermined relation to a transducer (24) and subjecting the so established system to at least two vibratory disturbances which differ from one another so as to thereby form resp...

More Information
Summary:Multi-phase systems are treated to enhance separability of at least one phase by establishing the multi-phase system in predetermined relation to a transducer (24) and subjecting the so established system to at least two vibratory disturbances which differ from one another so as to thereby form respective wave trains at different frequencies within the audio frequency range and thus establish a beat frequency difference, said one phase being thereby separated from the other phase(s). The expression "multi-phase systems" includes solid-solid systems such as mixtures of solid particles and also fluid characterised systems such as colloidal dispersions, suspensions and emulsions.
