FAP Pneumatic LNAPL Skimming System

EON features the FAP pneumatically operated system for actively skimming floating hydrocarbon from wells 2-inches and larger or from vertical casings installed in intercept trenches where free product accumulates. The

FAP is effective for petroleum liquids such as gasoline, diesel fluid, hydraulic fluids, and heating oils up to #6-grade. All installed components are pneumatic for use in flammable environments.

The FAP Plus consists of a flexible-body bladder pump that is suspended in the well above the liquid layer. A skimming float is attached to the bottom of the pump and floats at the product/water interface. A hydrophobic filter on the float separates the product from the water, down to sheen, allowing only hydrocarbon into the pump chamber where it is then pumped out of the well through discharge tubing. A second intake port located above the interface, allows product to bypass the filter and flow directly into the pump when the hydrocarbon layer is thicker than a few inches. This speeds recovery and reduces filter maintenance.

The standard skimming filter assembly intake accommodates up to 36 inches of vertical travel and tracks water level fluctuations.
