Can remove light LNAPLs such as Petrol/Gasoline, diesel, fuel oil, home heating oil, jet fuels, aviation fuel

The economy skimmer incorporates a density float and a hydrophobic filter through which only LNAPL will pass.  The filter has an overflow for enhanced product recovery rates where the product thickness exceeds the height of the filter.

 

The float and filter assembly is installed within a PVC screen within which the float can rise and fall freely with changes in the water level.  The integral pump head is fitted to the top of the screen and pumps recovered LNAPL from the filter via a flexible tube connected to the base of the filter.  This tube hangs below the skimmer assembly to facilitate freedom of travel.  The pump operates by means of a single diaphragm.

Tech Tip: Remember, as LNAPL is removed, the water level rebounds UP.  Position the middle of the tracking range at the TOP of the LNAPL layer.  As the product is removed, the product/water interface will rise to this level.
