DE 19937989 A UPAB: 20010402 NOVELTY - An extraction unit selectively transfers water/sand mixture from the sand chamber or separated oil and water/oil sludge mixture from the oil separator. The sand separator (2) removes water and sand from the extracted water/sand mixture. An oil separator (7) separates oil and water fractions from the water/oil sludge mixture. DETAILED DESCRIPTION - A sand storage unit and an oil storage unit (6) hold separated sand or separated oil and if appropriate, oil sludge. Adsorption filters (4, 8) clean the separated water. An INDEPENDENT CLAIM is included for the corresponding method of treatment. Preferred features: Storage (9.1) is provided for separated oil sludge. Water outlets from the sand separator and/or oil separator are each connected to an adsorption filter (4, 8). The adsorption filter is coke-filled, the coke being made from lignite or hard coal. The extraction unit can remove separated oil and oil/sludge mixture separately. The separated oil is introduced directly into the oil storage unit. The oil separator is a coalescer. A screw classifier (9) further separates oil sludge removed by the oil separator. A vacuum chamber (1) is connected with its inlet to the extraction unit for water/sand mixture. Its output is connected to the sand separator, e.g. a hydrocyclone or a thickener. A screw classifier further separates sand removed in the sand separator. A water storage tank holds the cleaned water. The extraction unit includes a coarse sieve. USE - A mobile treatment unit carrying out disposal from oil separation plant. ADVANTAGE - This unit disposes from e.g. an oil separation plant of an industrial concern, the latter operating in accordance with DIN 1999. It treats on the spot. This contrasts with the earlier method of carrying off and possibly re-mixing the contents of the separation plant. This special waste is costly to dispose of. The new mobile unit is economical, simple and efficient in operation. The purified water is returned directly to the oil separation plant; it no longer needs to leave the site
