Remedial Support Skimmer For Hydrocarbons
The Hydro-Skimmer passive recovery device is a patented one piece counterbalanced skimmer used to recover light floating hydrocarbons down to a sheen. The Hydro-Skimmer was designed to provide faster servicing of the hydrophobic element, higher product recovery rates, larger collection volumes which extend the time between servicing, greater ability to operate in wells with large water table fluctuations (entire device follows the water/product interface) or wells with little water. The Hydro-Skimmer design offers a specially designed vent chamber which prevents hydrostatic forces from forcing water through the hydrophobic element. This vent chamber also has replaced the requirement for an external vent tube. Our collection chamber is clear and calibrated for quick inspection and measurement. Our skimmers contain no contaminating glues of any kind and fit easily into a 2" well.

Installation Procedure
1.Take placement measurements:
A. Total well depth to top of well casing
B. Depth to water
C. Depth to hydrocarbon product
Taking the above measurements is important because when installing the Hydro-Skimmer, the displacement of water may create a false water table and cause the Hydro-Skimmer to be installed at a improper height, impeding collection.
2. Attach safety cord to eyebolt at top of Hydro-Skimmer.
3. Installation can be accomplished more easily with the use of color cut paste or a interface meter to determine that the water/hydrocarbon interface comes within two to three inches of the lower slotted area of the Hydro-Skimmer. If color cut paste or interface meter is not available, SLOWLY lower Hydro-Skimmer into well, allowing it to locate its own buoyancy.
4. Remove Hydro-Skimmer from well. The Hydro-Skimmer is pre weighted to be buoyant with the water/hydrocarbon interface, ideally within two inches of the lower slotted area of the skimmer. If the Hydro-Skimmer is not resting in this position, the following conditions should be consider:
A. If the hydrocarbon thickness as measured in step 1 exceeds 12” , the Hydro-Skimmer will ride above the suggested level but will function properly as it will weight itself when collection of hydrocarbon products begins.
B. If the hydrocarbon product is in excess of 6”, the Hydro-Skimmer will collect to capacity in approximately 1 hour, thus requiring the collection chamber to be emptied.
C. If water salinity does not allow the Hydro-Skimmer to rest within the recommended water/hydrocarbon area, galvanized washers (included in shipment) may need to be threaded into the safety connector to weight the unit so that EFFECTIVE collection may take place.
5. After above adjustments have been made, reinsert the Hydro-Skimmer into well allowing 4” slack in safety connector between the eyebolts when well cap is in its installed position.
Removal Procedure
A.
Remove Hydro-Skimmer from well
B.
Hold unit upright over recommended hydrocarbon collection container and open valve at base, allowing product to drain into container.
C.
Close valve and reinsert Hydro-Skimmer into well following installation procedures as outlined above.
1. Maintenance of skimmer element: the Hydro-Skimmer is designed with removable hydrophobic element, thus allowing it to be cleaned. REMOVE hydrophobic element only when necessary. Replacement elements are available if the element becomes damaged.
A. Remove upper vent chamber cap from Hydro-Skimmer. With your fingers, carefully pull up on the inner aluminum tube. This will disengage the hydrophobic element from an O-ring seal in the lower housing.
B. The element may be sprayed or immersed in any EPA approved hydrocarbon cleaning solution. If immersed in a solution, use a gentle rotation action to facilitate cleaning. Do not squeeze or mash on plastic webbing area.
C. To reinstall the hydrophobic element, place a non-hydrocarbon lubricant such as soap on the lower two inches of the aluminum tubing. Check bevel on lower Place element in Hydro-Skimmer and align with hole in lower housing. Gently push down on element (approximately one inch) until it is fully engaged in the lower housing. The element is held in place when upper vent chamber cap is fully screwed onto the top of the Hydro-Skimmer.
