Abstract
Oil polluted water or solid adsorbents are treated with microbially produced glycolipids to separate the oil phase. The treatment may be carried out in an apparatus which can be taken to the site and which comprises a mixing vessel supported by an undercarriage and provided with a storage container to supply the glycolipids, filling means, overflow discharge means and outlet means at its base.
Claims5
A process for separating oils or petroleum hydrocarbons from a sorbent material saturated with said oils or petroleum hydrocarbons which consists essentially of mixing said sorbent material with an aqueous solution or dispersion of microbially produced glycolipids to form a slurry and separating the oil-containing phase rising out of the aqueous phase, wherein said sorbent material is selected from the group consisting of hydrophobic, thermally expanded vermiculites and perlites.
