Selective Oil Skimmers
SOS Models: SOS-2 For 2-inch wells; five models for tidal, dual pump, high-water, and shallow wells SOS-4 For 4-inch wells; six models for tidal, dual pump, high-water, and shallow wells The family of Selective Oil Skimmers (SOS) when coupled with shallow or deep-well product pumps, are designed to recover free-floating hydrocarbon down to a sheen (< 0.01 inches) from depths up to 250 feet (76m). The floating intake head follows water table fluctuations and with optional features, such as High-Water Shut-Off (HWSO), will automatically turn off the product pump temporarily to prevent potential water contamination. Alternate size SOS Skimmers are available for operating in 2-inch (5cm) and 4-inch (10cm) diameter wells. Tidal skimmers with extra long strokes are also available for sites with high and low tide considerations. The SOS Skimmer consists of three main items: a Floating Intake Head, Guide Rod & Flexible Tube, and 2 Well Centering Disks.

Product Description
The skimmer is lowered into the well until the midpoint of the skimmer's travel is located at the fluid level in the well and then connected to a surface or down-well mounted product pump.
The skimmer has a floating intake head that follows the fluctuating water table. Hydrocarbon first enters the skimmer through the floating intake's outer debris screen and then an inner oileophilic hydrophobic screen, down through a flexible, yellow tube, through the product pump, and into a product storage tank.
FLOATING INTAKE HEAD
All product which enters the floating intake head passes down through the flexible tube, up into the hollow guide tube, and is drawn out of the well by a product pump.
The Floating Intake Head:
• Consists of an outer debris screen, a floatation collar, and an inner semi-permeable (selective) screen which allows liquid hydrocarbons to pass and repels water.
• Reduces product level to a sheen (< 0.01 in.).
• Floats at the product-water interface in the well and automatically adjusts to any fluctuation of the groundwater within its travel range.
• Slides on a hollow, stainless steel guide tube which passes down through the center of the skimmer head.
• Is connected to the guide tube via a flexible (fuel rated) tube which hangs below the skimmer head and guide tube.
SKIMMER OPTION
SOS Skimmers can be used in conjunction with groundwater depression. When using SOS Skimmers, the groundwater hose must go along side the skimmer itself. The SOS Skimmer is placed inside a slotted PVC tube so the water depression hoses do not interfere with the floating intake skimmer head. CEE can provide either pneumatic or electric water depression pumps, depending upon the water drawdown rate.
