METHOD FOR REMOVAL OF IMPURITIES FROM LIQUID MIXTURES ABSTRACT OF THE DISCLOSURE The invention provides a method for the removal of liquid or solid impurities from an impurity-containing liquid mixture wherein the impurities are emulsified or finely suspended in the liquid medium. The method comprises kneading the impurity-containing liquid mixture with a viscoelastic material having an affinity for the impurities and having substantially no affinity for the liquid medium, thereby causing the viscoelastic material to take up the impurities, and then separating the purified liquid medium from the viscoelastic material. By this method, various liquid wastes can be purified, and valuable resources can be recovered from the wastes and re-used. The separated liquid medium, if not useful, can be thrown away without causing environmental pollution problems.
