Abstract
This invention relates to a method for the removal of oil from an oil in water emulsion by passing the emulsion through a fibrous structure comprising fibres having finely divided particles having an average size of one micron or less and which exhibit oleophilic and hydrophobic properties adhered to and penetrating their outer surfaces, and removing the coalesced oil droplets so formed.
