An apparatus and method for skimming contaminants from a reservoir of a liquid such as an industrial solvent, including a tubular wand having an end inlet extending into the reservoir, a pressure air line extending along the wand, the air line protruding a side wall of the wand and terminating at a nozzle proximate the inlet, the nozzle being directed into the wand, away from the inlet for producing a vacuum. The wand is adjustably mounted to a base that attaches to the reservoir, and is connected to a vented container for collecting the contaminants that are drawn into the wand. Contaminants can be removed from the surface of the liquid, from proximate the bottom of the reservoir, or from a submerged layer concentrated at an intermediate depth within the reservoir.

A pneumatic skimming apparatus for removing contaminants from a liquid reservoir, comprising: (a) a tubular wand member having an end inlet; (b) means for supporting the wand member relative to the reservoir with the inlet of the wand member extending downwardly into the reservoir, the means for supporting the wand member comprising: (i) a base; (ii) mount means for mounting the base in fixed relation to the reservoir, the mount means comprising a horizontally disposed plate surface of the base for resting on an upper extremity of the reservoir and a locating member fixably connected to the base and extending downwardly from the plate surface for engaging a side wall of the reservoir; and (iii) locating means on the base for fixably locating the wand member; (c) a nozzle mounted within the wand member proximate the inlet thereof, the nozzle being oriented within the wand member in a direction away from the inlet; (d) means for connecting the nozzle to a source of pressurized gas whereby a vacuum is produced at the inlet; (e) a vessel for receiving the contaminants; and (f) means for fluid connecting the wand member to the vessel, whereby the contaminants are drawn from the reservoir and transported from the wand member into the vessel.
