Abstract: A surgical drape and suction head combination for attaching the suction head to a wound area. The suction head comprises a planar flange portion and a tubular connector piece on a first face that communicates with an aperture extending to a second face. The second face is formed with projections that define flow channels for facilitating flow of liquids to the aperture.

Abstract: Systems and techniques for remediation of soil, vapor and groundwater contaminated with hydrocarbons. The system is ideally suited for easy integration into a mobile remediation unit that uses a liquid ring vacuum pump to extract a contaminated mixture from a sub-surface formation and direct it into a separator, which also serves to shield the high-flow vacuum pump from non-gaseous phases of the contaminated matter that would otherwise reduce its efficiency. Cooling systems are employed to render the unit more independent and self-contained, and an automatic vent and low-shear pump-down cycle is used to transfer liquid phases to fractionation subsystems with minimal emulsification.
