  • QED SOS AutoGenie Active Skimmer

    • SOS (selective oil skimmer) uses a hydrophobic screen float, designed to recover less viscous hydrocarbons
    • All Genie skimmer systems pump the LNAPL using a special bladder pump with high suction capability, positioned above the floating inlet section of the system
    • The use of a bladder pump eliminates air contact with the LNAPL fluids, minimizing emulsification and eliminating VOC emissions
    • The AutoGenie uses an integral pneumatic timer to control the pump fill and discharge times
    • The Programmable Genie uses an electronic controller mounted outside the well to allow adjustment of pump cycles and off times
    • A complete line of matched accessories is available to help with installation and performance
