    DOCUMENTATION CONVENTIONS This uses the following conventions to present information: An exclamation point icon indicates a WARNING of a situation or condition that could lead to personal injury or death. You should not proceed until you read and thoroughly understand the WARNING message.

    (or buoy), a control panel that can be mounted indoors or out, an optional Tankfull Shut-off Sensor, air and discharge lines, and an optional air compressor. The PRS’ unique product intake assembly, or Skimmer, incorporates both a density float and an oleophilic/hydrophobic filter that differentiates between floating hydrocarbons and water.

  • Page 6: Specific Gravity And Viscosity Limitations

    The specific gravity of the product to be recovered must be less than 1.0 and its viscosity less than 50 SSU for use with the “light” oil filter, and 400 SSU for use with the “heavy” oil filter cartridge. Consult Geotech for product recovery operations with viscosities outside that range.
  • Page 7 Figure 1-3: Standard 2” and 4” Skimmer Attachments A Skimmer assembly will not draw water unless the intake cartridge is forcibly submerged, surfactants are present, or when the “conditioning” of the intake screen has been removed. See Section 4: System Maintenance for information on rec-conditioning the intake screen.
  • Page 8 Heavy Oil Skimmer Attachment The optional Heavy Oil Skimmer attachment is designed to recover a range of fluids from gasoline to gear oil, skimming the product down to .01’ (3 mm) in 4” (10 cm) diameter and larger wells. This option is best suited when the viscosity of the hydrocarbon is greater than the capability of the filter screen technology (screen can no...
  • Page 9 4 CFM (.11 CMM) at 90 PSI (6 bar). The PRS Control Panel comes equipped with a Tankfull Shut-off feature. The Tankfull Shut-off incorporates a manual reset button as an additional safety feature. When the product recovery tank becomes full, the Tankfull Shut-off Sensor shuts off the system.
  • Page 10 Tankfull Shut-off Sensor (Optional) The Tankfull Shut-off Sensor assembly (Figure 1-6) consists of a sensing tube that is connected to the control with a sensor airline. The control needs to be within 50’ (15 m) of the discharge tank. When the product rises approximately 11” (28 cm) up the side of the sensing tube, the level control valve within the control panel shuts off air supply to the pump.
  • Page 11 Product Recovery Tank (Purchased Separately) A product recovery tank with a 2” NPT bung opening for the Tankfull Shut-off Sensor tube, a product inlet opening, and a vent are required for proper operation – typically a 55 gallon (208 liter) drum or other suitable container. Check government regulations regarding fuel storage before selecting a recovery tank.

  • Page 12: Section 2: System Installation

    Section 2: System Installation Planning Your PRS Installation To successfully plan the installation of the PRS, use the following guidelines to determine a suitable location for the control panel, pump, air compressor, Tankfull Shut-off Sensor, and recovery tank. Also, refer to the System Schematic found in Section 7: System Schematics.
  • Page 13 Pull the measured lengths of airline and discharge hose through the fittings on the well cap. Fully tighten the compression fittings.  The well cap will suspend the pump and Skimmer by the discharge hose, setting the intake assembly at the midpoint of its travel range. Attach the airline and discharge hose to the pump using the provided compression fitting and hose clamp respectively, and set the pump and Skimmer in the well.

  • Page 16 The pumping rate may be reducing the system air pressure. 45 PSI (3 bar) minimum to 60 PSI (4 bar) is required to operate bladder pump. Tankfull Shut-off Sensor  A minimum of 45 PSIG (3 bar) air pressure is required for operation. ...

  • Page 17: Section 4: System Maintenance

    Section 4: System Maintenance Always ensure all hose and tubing fittings at the pump and between the pump and Skimmer are tight prior to deploying the unit into the well. Weekly Maintenance  Turn the air compressor off and drain the air tank(s). On air compressors without an optional automatic condensate drain, open the drain fitting on the bottom of the compressor tank(s) and drain any accumulated water.

  • Page 18: Quarterly Maintenance

    Quarterly Maintenance  Pull pump and Skimmer from the well.  Clean the well screen (site specific, primarily to clear bio growth and keep thick degraded product from impeding conductivity to the well at the product layer. Frequency to be determined by user). ...
  • Page 19 Slide the lower housing off. Unscrew the old bladder from the upper housing and screw on the new one.  The bladder can be tightened snugly by hand. Re-attach the lower housing to the upper pump assembly.

  • Page 20: Section 5: System Troubleshooting

    Reset the pump and skimmer. The pump bladder has ruptured.  Replace the pump bladder or contact Geotech for further information. Problem: The pump cycles but does not discharge product. Solutions: One or both of the pump check valves are malfunctioning.
  • Page 21  Use a circuit with larger amperage rating. The air compressor has an electrical problem.  Contact the air compressor manufacturer directly or contact Geotech for further information. Problem: The air compressor runs constantly. Solutions: There is an air leak in the air compressor or airline.
