ABSTRACT:
A method of removal of polycyclic aromatic hydrocarbons (PAH) by precoat vacuum filtration is characterized in that organic particles are present in the precoat which, when subjected to a specific precoat layer build-up test, have a layer thickness in the range 30-200 mm. The immersion depth of the drum during the filtering is more than 40% of the drum diameter. Improved filtering results. A method of testing a finely divided organic material in order to determine its suitability for precoat vacuum filtration is also disclosed.
